# Hosted / SaaS Wiki & Knowledge-Base Platforms **Scope:** Platforms where the user signs up and the vendor handles all infrastructure, updates, backups, and uptime. Covers team wikis, customer-facing KBs, and community/fan wikis. Current as of **2026-04**. **Confidence tiers:** C1 primary source / C2 credible secondary / C3 inferred / C4 anecdotal / C5 unknown. --- ## Summary / Key Takeaways 1. **Team wiki / internal KB is a crowded, mature category** — Notion, Confluence, Slite, Slab, Nuclino, Tettra, Guru, Coda, ClickUp Docs all overlap heavily. Differentiation comes from (a) AI Q&A quality, (b) Slack-native workflows (Tettra, Guru), (c) database/app power (Notion, Coda), and (d) price floor (Nuclino/Slite free tiers vs. HelpJuice's $120/mo minimum). 2. **Customer-facing/public KB is bifurcated** — GitBook and Document360 target technical writers and product teams with custom domains + SEO; HelpJuice/Helpscout-style tools target support/ops teams. GitBook's $65/mo *per custom-domain site* is a real sticker shock. 3. **Notion dominates mindshare** but has weak SEO by default for public publishing. Third-party layers — Super.so, Feather, simple.ink, Fruition — exist to patch that gap; none are free at scale. 4. **Confluence Cloud is the enterprise default** by installed base, not love. Atlassian raised list prices 5-10% in October 2025 (C2). Free tier is 10 users. 5. **Fandom has been hemorrhaging major gaming communities since 2022**: RuneScape (2018), Zelda + Terraria (2022), Minecraft + Fallout + Hollow Knight (2023), South Park + Dead by Daylight + League of Legends (2024), Warframe + Undertale/Deltarune + Balatro (2025). Destinations are mostly **wiki.gg** (for-profit, gaming-focused, light ads) or self-hosted MediaWiki. Fandom CEO Perkins Miller resigned Oct 2025; Jay Sullivan named CEO Feb 2026 (C2). 6. **Miraheze/WikiTide is the non-profit MediaWiki-hosting refuge** — 501(c)(3), ad-free, ~20,000 wikis, runs on donations (~$25K/yr server target). 7. **Lock-in risk is real but manageable**: Notion exports to Markdown but loses relations/formulas/rollups; Confluence exports HTML/XML/PDF (with known fidelity issues); GitBook's Git Sync is the gold-standard portability story. 8. **Do not assume stated pricing is current.** Many "2026 pricing" articles are AI-generated SEO spam recycling 2023 data — pricing claims here are flagged C2/C3 where verified only against secondary aggregators; C1 requires the vendor's own /pricing page. --- ## Comparison Table | Tool | Free tier | Paid entry ($/user/mo) | Custom domain | Public SEO | SSO | Audience | Lock-in | |---|---|---|---|---|---|---|---| | Notion | Yes (unlim. pages, 10 guests) | $10 Plus / $20 Business | Paid plan (or Super.so/Fruition) | Poor by default | Business+ | Team + personal | Medium (MD export lossy) | | GitBook | Yes (open-source / small) | $10 Plus | Yes, **$65/site/mo** | Good (purpose-built) | Yes (Premium+) | Dev docs, public KB | Low (Git Sync) | | Confluence Cloud | 10 users | ~$5.16 Standard | Limited/via proxy | Moderate | Premium+ | Enterprise team | Medium-high | | Slab | No | $8 Startup / $15 Business | Yes (Business) | Moderate | Business | Team | Medium | | Guru | No (trial) | $25 Self-Serve (10-seat min.) | Yes | N/A (internal) | Yes | Support / sales enablement | Medium | | Tettra | No (trial) | $5 Basic (10-seat min.) | Limited | N/A (internal) | Scaling+ | Small teams on Slack | Low-med | | Slite | Yes (50 docs) | $8 Standard / $25 Suite | Limited | N/A (internal) | Premium | Team | Low (MD) | | Document360 | **Discontinued Nov 2024** | Quote-only (~$99-299/mo est.) | Yes | Strong | Yes | Customer-facing KB | Medium | | HelpJuice | No (14-day trial) | **$120/mo flat (4 users)** | Yes | Strong | Yes | Support KB | Medium | | Nuclino | Yes (50 items) | $6 Starter / $12.50 Business | Yes (Business) | Moderate | Business | Small team wiki | Low (MD) | | Coda | Yes (basic) | $10 Pro / $30 Team (doc makers only) | Limited | Weak | Enterprise | Docs-as-apps | Medium-high | | ClickUp Docs | Yes | $7 Unlimited / $12 Business | Limited | Weak | Business+ | PM-centric teams | Medium | | Fandom | Free (ad-supported) | N/A (free to creators) | No (fandom.com only) | Very strong | N/A | Community/fan wikis | **High** (domain owned by Fandom) | | wiki.gg | Free (light ads) | N/A | wiki.gg subdomain | Good | N/A | Gaming communities | Low-med (MediaWiki export) | | Miraheze / WikiTide | Free (donation-funded) | N/A | Yes (custom domain) | Good | MediaWiki-native | Non-profit/community | Very low (full MW XML) | | Fextralife | Free (ad-heavy) | N/A | No | Strong | N/A | Gaming guides | High | | Archbee | No (14-day trial) | $50/mo base (3 users) + add-ons | Yes (+$80 add-on common) | Moderate | Growth+ | Dev/product docs | Medium | | Stonly | Limited | Custom/quote | Yes | Moderate | Yes | Interactive guides/support | Medium | | BetterDocs | Plugin + free tier | $69/yr (self-host on WP) | Via WordPress | Depends on WP | Via WP | WordPress KB | Low (it's WordPress) | --- ## 1. Notion **Pitch:** All-in-one workspace combining docs, wikis, databases, and AI. Target: teams, startups, individuals. Also used public-facing via third-party layers. **Pricing (C2, [Notion /pricing](https://www.notion.com/pricing)):** - Free: unlimited pages, 10 guests, 5 MB file upload cap. - Plus: $10/user/mo ($8 annual). - Business: $20/user/mo ($15 annual) — unlimited AI, SSO via Google, unlimited version history. - Enterprise: custom (SCIM, audit log, data residency). **Editor:** Block-based (each paragraph/heading/image is a draggable block), no true markdown source view but accepts `/` commands and Markdown shortcuts. C1 from daily use. **Public publishing + custom domain:** - Native "Publish to web" gives a `notion.site` URL. - Custom domain now built-in on paid plans ("Notion Sites"), but SEO is weak by default — [Super.so blog](https://super.so/blog/is-notion-good-for-seo) and [simple.ink FAQ](https://www.simple.ink/faq/is-notion-good-for-seo) flag slow indexing, no auto sitemap, no robots.txt control (C2). - Third-party layers for better SEO + custom domain: **Super.so** (polished, paid), **Feather**, **simple.ink**, **HostNotion**, **Fruition** (free, open-source Cloudflare Worker — periodically breaks when Notion's internal API changes) (C2). **Permissions:** Workspace/page level; granular ACL on Business+. SSO (SAML) on Business+, SCIM on Enterprise. **Integrations:** Slack, GitHub (new: AI search across GitHub — beta Sep 2025, [OpenAI](https://openai.com/index/notion/)), Google Drive, Jira, Zapier. Public REST API. **Notion 3.0 (Sep 2025)** introduced multi-step AI agents with GPT-5/Claude Opus/o3 (C2, [openai.com/index/notion](https://openai.com/index/notion/)). **Import/export:** Export to Markdown (per page) or HTML/CSV; relations/formulas/rollups are always lost on export ([Notion Help](https://www.notion.com/help/export-your-content), C1). Import from DOCX/CSV/MD/HTML/XLSX/EPUB. **Company health:** ~$500M ARR (Sep 2025), ~100M users, ~5,700 employees (Mar 2026), tender offer at $11B valuation (Dec 2025) (C2, [Sacra](https://sacra.com/c/notion/), [PitchBook](https://pitchbook.com/profiles/company/168506-47)). No major layoffs reported in public trackers for 2024-2026. **Killer features:** Databases (relational), AI Q&A with citations across workspace + connected apps, massive template ecosystem, brand recognition. **Weaknesses:** Weak public SEO without third-party layers; block bloat on long pages; search historically mediocre (improving with AI); AI locked to Business+ in 2025 pricing revamp. **Notable public wikis/sites:** Loom's help center (historically), many YC startup handbooks, Super.so showcase gallery. --- ## 2. GitBook **Pitch:** Docs platform for technical products — Git-synced Markdown, custom-domain public sites. Target: developer docs, open-source projects, public help centers. **Pricing (C2, [gitbook.com/pricing](https://www.gitbook.com/pricing), [featurebase.app](https://www.featurebase.app/blog/gitbook-pricing)):** - Free: open-source/non-profits/small. - Plus: $10/user/mo (basic collaboration). - Pro / Ultimate: higher tiers with AI, analytics. - **Custom domain: $65/site/mo** — a real cost trap for agencies maintaining many sites. - Readers on *public* sites are free; private help-center readers counted. **Editor:** Block-based WYSIWYG *plus* raw Markdown via Git Sync — technical writers and devs can both contribute ([gitbook.com/features/git-sync](https://www.gitbook.com/features/git-sync), C1). **Public publishing:** Primary product. Custom domain supported. SEO is intentionally strong (sitemaps, clean URLs, meta tags) — purpose-built for docs that need to rank. **Permissions:** Space-level, role-based. SSO on higher tiers. **Integrations:** GitHub/GitLab 2-way sync (killer feature), Slack, Intercom, Linear, Mixpanel. REST API. **Import/export:** Git Sync makes it nearly impossible to lock you in — your docs are Markdown files in your repo. Strongest portability story in this list. **Company health:** French (Lyon), founded 2014. ~35 employees, ~$3.9M revenue 2025 (C2, [getlatka.com/companies/gitbook.com](https://getlatka.com/companies/gitbook.com)). Backed by Fly Ventures, Point Nine. Small but profitable/stable; no layoff news. **Killer features:** Git Sync, AI search across published docs, clean default theming, strong SEO defaults. **Weaknesses:** Custom-domain pricing scales linearly per site ($65 × N sites), no free custom domain, AI agent features behind higher tiers. **Customers:** Swarmia, many YC/dev-tool companies ([gitbook.com/customers](https://www.gitbook.com/customers/swarmia)). --- ## 3. Confluence Cloud (Atlassian) **Pitch:** Enterprise team wiki with deep Jira integration. Target: engineering/ops teams already on Jira. **Pricing (C2, [atlassian.com/software/confluence/pricing](https://www.atlassian.com/software/confluence/pricing)):** - Free: up to 10 users, unlimited pages/spaces, basic Atlassian Intelligence. - Standard: ~$5.16/user/mo. - Premium: ~$9.73/user/mo (analytics, automation). - Enterprise: custom. - **Price increases October 2025**: Standard +5%, Premium +7.5%, Enterprise +7.5-10% (C2, [redresscompliance](https://redresscompliance.com/confluence-cloud-pricing-tiers-enterprise-cost.html)). - Volume discounts: 15% off 101-250 users, 29% off 251-1000. **Editor:** Block-based modern editor ("cloud editor") with inline macros; legacy editor still exists for older macros. Atlassian Intelligence AI summarization + writing help integrated. **Public publishing:** Not primary — pages can be set to "anyone with link" but not a true public-domain KB. For customer-facing use, Atlassian pushes toward **Jira Service Management** or third-party apps (Scroll Viewport, Refined) to theme/publicize Confluence content. Custom domain requires paid app. **Permissions:** Space-level + page restrictions; SSO/SAML on Premium+; Atlassian Guard for SCIM. **Integrations:** Jira (native), Slack, Teams, Trello, GitHub, Figma, Loom. Thousands of Atlassian Marketplace apps. **Import/export:** Export page/space to PDF, HTML, XML ("Confluence Cloud space backup"). Import from Word, HTML, older Confluence. Migration tools exist (Atlassian Cloud Migration Assistant). Fidelity is imperfect — complex macros/attachments often break (C3, widely reported on Atlassian community). **Company health:** Atlassian NASDAQ-listed (TEAM), ~$4B revenue run-rate, highly stable. Acquired Loom (2023), The Browser Company ($610M Sep 2025), DX ($1B Sep 2025) (C2, [Work Life by Atlassian](https://www.atlassian.com/blog/announcements/atlassian-acquires-dx)). **Killer features:** Jira pairing, mature enterprise governance, Marketplace ecosystem. **Weaknesses:** Heavy UX, slow perceived, macro fragmentation between old/new editor, price creep, limited native public-KB story. **Customers:** NASA, Netflix, Facebook, ~300,000 Atlassian customers total (C2). --- ## 4. Slab **Pitch:** Modern team wiki with strong search and clean UX. Target: mid-size teams wanting something less heavy than Confluence, more focused than Notion. **Pricing (C2, [slab.com/pricing](https://slab.com/pricing/), [getapp.com/a/slab](https://www.getapp.com/collaboration-software/a/slab/)):** - Startup: $8/user/mo. - Business: $15/user/mo (SSO/SAML, advanced permissions, analytics). - Free tier status: historically had one; check /pricing directly. **Editor:** Real-time collaborative WYSIWYG with Markdown shortcuts. **Public publishing:** Public posts option on Business plan with custom domain; not primarily used as a public-facing KB. **Permissions:** Folder + post; SSO/SAML on Business. **Integrations:** Slack, G Suite, GitHub, Asana, Jira, Trello, Zendesk. **Import/export:** Markdown export; imports from Confluence, GitHub, Dropbox Paper, Quip, Guru, Google Docs (C2). **Company health:** Founded 2017, Series A ($2.2M) 2018, **no new funding since** (C2, [Crunchbase](https://www.crunchbase.com/organization/slab)). ~$3M revenue 2024, ~11-50 employees, profitable/bootstrapped-like posture. Small, slow-growth, but stable. **Killer features:** Very fast, clean UI, strong search, "Topics" cross-folder organization. **Weaknesses:** Small company (single point of failure risk), limited AI features vs. competitors, modest integration depth. **Customers:** Asana, Pinterest (historically), startups. --- ## 5. Guru **Pitch:** AI-powered internal KB and enterprise search — surfaces answers in Slack/browser where you already work. Target: customer support, sales enablement, internal Ops. **Pricing (C2, [getguru.com/pricing](https://www.getguru.com/pricing)):** - Self-Serve: $25/user/mo, 10-seat minimum ($250/mo annual or $300/mo monthly). - Enterprise: custom, often priced by active usage rather than seats. **Editor:** "Card"-based (atomic knowledge units) with WYSIWYG; verification workflow built in (trust states, re-verify cadences). **Public publishing:** Not a public-wiki tool — optimized for internal answer retrieval. Some HelpCenter/public-KB features added 2024-2025. **Permissions:** Collections + groups, SSO/SAML, SCIM. **Integrations:** Slack (flagship — ask Guru right in Slack), MS Teams, Chrome extension, Salesforce, Zendesk, Intercom, ServiceNow. "Guru GPT" lets ChatGPT search connected apps. **Import/export:** Import from Confluence/Notion; export to CSV/HTML. **Company health:** Independent. Raised $166M total across rounds (historical, C3). Not acquired by Atlassian — that rumor is unsubstantiated by the sources checked. Shift toward "AI-native search" / Agentic Search 2024-2025. **Killer features:** Slack integration, verification workflow (cards decay and ping owners), agentic AI answering, Chrome overlay. **Weaknesses:** 10-seat minimum pricing is a floor even for small teams, heavy for pure wiki use case. **Customers:** Shopify, Spotify, Slack itself (historically), many support orgs. --- ## 6. Tettra **Pitch:** Slack-native internal wiki and AI Q&A for small-to-mid teams. Target: companies using Slack as primary communication. **Pricing (C2, [tettra.com/pricing](https://tettra.com/pricing/), [featurebase.app](https://www.featurebase.app/blog/tettra-pricing)):** - Basic: $5/user/mo (annual) or $4, **10-user minimum**. - Scaling: $8/user/mo (adds AI bot in Slack, advanced permissions, analytics, API). - Professional: 50-user minimum. **Editor:** Simple WYSIWYG with Markdown shortcuts — explicitly simpler than Notion. **Public publishing:** Limited — primarily internal. **Permissions:** Category + page; SSO on Scaling+. **Integrations:** Slack (flagship: ask Kai, Tettra's bot, inline), MS Teams, Google Drive, GitHub. **Import/export:** Markdown import/export, Confluence import. **Company health:** **Acquired by GSoft (Canadian, also owns ShareGate, Officevibe) in October 2023** (C2, [LinkedIn announcement](https://www.linkedin.com/posts/damengchen_supportmanio-has-been-acquired-by-tettra-activity-7262918008174501888-03J_)). Acquired Supportman late 2024. ~$3.2M revenue 2024 (C2, getlatka). Small but now parented by a larger SaaS holdco. **Killer features:** Kai (AI Slack bot that answers from your wiki), lightweight onboarding, "knowledge requests" workflow. **Weaknesses:** 10-user minimum hurts very small teams; editor simpler than some prefer; limited public KB features. **Customers:** Many SaaS teams (MicroConf, early-stage startups). --- ## 7. Slite **Pitch:** AI-first team knowledge base with "Ask" RAG-style Q&A. Target: distributed teams. **Pricing (C2, [slite.com/pricing](https://slite.com/pricing), [featurebase.app](https://www.featurebase.app/blog/slite-pricing)):** - Free: 50 docs, 50 users — real free tier. - Standard: $8/user/mo annual, 30 AI questions/user/mo. - Knowledge Suite: $25/user/mo (replaces deprecated Premium) — KB + Enterprise Search, 100 AI questions/user/mo. **Editor:** Clean block-based WYSIWYG with Markdown shortcuts. **Public publishing:** Public share links + limited custom-domain theming on higher tiers. **Permissions:** Channel-based (like Slack-inspired), SSO on higher tier. **Integrations:** Slack, Asana, Jira, Google Drive, GitHub. **Import/export:** Markdown import/export, Confluence/Notion/Google Docs import. **Company health:** French, YC alum, Series A $11M (2020), **no new funding since 2020** (C2, [Tracxn](https://tracxn.com/d/companies/slite/__KGA8Frx1XztLwVKLq1OrAznQKdhifPyLsSAPyqHXBmU)). ~$5.5M revenue 2024, ~37 employees 2025. Small and lean; has iterated steadily into AI positioning. **Killer features:** AI "Ask" with citations (RAG), document verification reminders, clean UX. **Weaknesses:** Small team raises longevity risk; AI question caps; limited public-facing features. **Customers:** Many SaaS/remote-first teams. --- ## 8. Document360 **Pitch:** Purpose-built customer-facing KB platform with versioning, workflows, analytics. Target: product/support teams building external help centers. **Pricing (C2):** - **Free tier discontinued November 2024** — moved to quote-only sales-led model (C2, [docsie.io pricing comparison](https://www.docsie.io/blog/articles/confluence-vs-document360-pricing-comparison-2026/)). - Estimated: Professional ~$99-119/mo, Business ~$249-299/mo, Enterprise custom. - Add-ons for extra workspaces, languages, readers (private KB), storage. **Editor:** Block + markdown + WYSIWYG modes, with category manager, article workflow states (draft/review/publish). **Public publishing:** First-class — custom domain, branded portal, built-in SEO (sitemap, meta, schema), reader analytics. **Permissions:** Fine-grained with reader groups for private KBs; SSO/SAML; multi-language. **Integrations:** Slack, Intercom, Zendesk, MS Teams, Freshdesk, Chrome extension, API. **Import/export:** Markdown/HTML import-export; Confluence importer. **Company health:** Made by **Kovai.co**, Coimbatore/London, bootstrapped. Document360 **crossed $10M ARR in 2025**, targeting $25M by 2028, investing ₹220 crore in Coimbatore expansion (C2, [YourStory Dec 2025](https://yourstory.com/2025/12/kovaicos-document360-crosses-10m-arr-eyes-25m-by-2028)). Healthy bootstrapped growth. **Customers:** VMware, NHS, Ticketmaster, Payoneer, Virgin Red, Comcast (C2, YourStory). **Killer features:** Purpose-built external KB (versioning, workflows, analytics), strong SEO defaults, custom domain. **Weaknesses:** Opaque pricing (sales-led), add-on bloat (each extra workspace/language costs more), no free tier anymore. --- ## 9. HelpJuice **Pitch:** Heavily customized, white-glove customer-facing KB; "handcrafted until pixel-perfect". Target: established support orgs with budget. **Pricing (C2, [helpjuice.com/pricing](https://helpjuice.com/pricing), [featurebase.app](https://www.featurebase.app/blog/helpjuice-pricing)):** - Starter: **$120/mo** (up to 4 users). - Run-Up: $200/mo (up to 8 users). - Premium: $289/mo (unlimited users, dedicated account manager). - AI KB plan ~$449/mo (100 users, 24GB). - Unlimited: $799/mo. - 14-day free trial, no free tier. **Editor:** WYSIWYG, designed for long-form help articles. **Public publishing:** First-class — custom domain, handcrafted theming by their team, 40+ language AI auto-translation. **Permissions:** Role-based, SSO, access control. **Integrations:** Slack, Zapier, Salesforce, Zendesk, Freshdesk, API. **Import/export:** HTML/CSV/Markdown, Confluence import. **Company health:** Private, bootstrapped-style, long-running (founded ~2011). Less transparent than VC-backed peers. Claims 130,000+ users across customer orgs. **Killer features:** White-glove theming service, multilingual AI translation, focused on analytics/search optimization. **Weaknesses:** Expensive floor ($120/mo for 4 users vs. $25/user minimums elsewhere), less dev-friendly than GitBook, small integration set. **Customers:** Amazon (historically), Hertz, Virgin — name-drop list per their site (C3 — customer lists are marketing, verify individually). --- ## 10. Nuclino **Pitch:** "The simplest team wiki" — fast, minimal, graph/board/list views. Target: small teams wanting less complexity than Notion. **Pricing (C2, [nuclino.com/pricing](https://www.nuclino.com/pricing)):** - Free: 50 items, 3 canvases, 2GB storage, unlimited members — *the most generous "real" free tier* in this list. - Starter: $6/user/mo (annual), unlimited items, 10GB/user, 30-day version history. - Business: $10-12.50/user/mo, SSO, advanced permissions. **Editor:** Fast, minimal block editor with Markdown shortcuts. Notably snappier than Notion. **Public publishing:** Public share + custom domain on Business. **Permissions:** Workspace + item, SSO on Business. **Integrations:** Slack, Google Drive, MS Teams, Figma, GitHub via embeds; API. **Import/export:** Markdown import/export; Confluence/Notion import. **Company health:** German, independent, profitable/bootstrapped-style. Minimal public funding info — seen as stable-but-small (C3). **Killer features:** Speed, simplicity, graph view showing link relationships, limited but thoughtful AI ("Sidekick"). **Weaknesses:** No database/spreadsheet power (by design), minimal customization, small brand footprint. **Customers:** Thousands of small teams; not marketed via logo-wall. --- ## 11. Coda (as wiki) **Pitch:** Docs that grow into apps — tables, formulas, automations, Packs. Target: ops/product teams wanting doc + lightweight app hybrid. **Pricing (C2, [coda.io/pricing](https://coda.io/pricing)):** - Free: limited doc size. - Pro: $10/Doc Maker/mo. - Team: $30/Doc Maker/mo ($36 annual / $48 monthly per other sources). - Enterprise: custom. - **Only Doc Makers billed; Editors/Viewers free** — unique pricing model. **Editor:** Block editor with powerful inline tables, buttons, formulas. Much more app-like than Notion. **Public publishing:** Public doc share + embed; custom domain limited/Enterprise; weak vs. dedicated doc sites for SEO. **Permissions:** Row-level in tables, per-doc access, SSO on Enterprise. **Integrations:** 450+ "Packs" (Jan 2026) — Slack, Google Calendar, Jira, Salesforce, Figma, etc. **Import/export:** Markdown export per page; CSV for tables. Re-importing to rebuild formula/button logic is painful — lock-in is moderate-to-high once you've built real Coda apps. **Company health:** **Acquired by Grammarly in December 2024** (C2 — confirm) — now "Grammarly Coda" on G2 listings. Strategic direction uncertain post-acquisition; no reports of layoffs or product sunsetting as of Apr 2026. **Killer features:** Tables-as-databases with formulas, buttons-as-automation, Packs, Doc-Maker-only pricing. **Weaknesses:** Learning curve, lock-in risk on complex docs, public-KB story is weak, post-acquisition uncertainty. **Customers:** Figma, Uber, Square (from Coda's own showcase, C3). --- ## 12. ClickUp Docs **Pitch:** Wiki tightly coupled to ClickUp's PM platform. Target: teams already using ClickUp for tasks. **Pricing (C2, [clickup.com/pricing](https://clickup.com/pricing)):** - Free Forever: unlimited tasks/members, collaborative Docs + Whiteboards, 100MB storage. - Unlimited: $7/user/mo. - Business: $12/user/mo (Google SSO, workload mgmt, private Docs). - Enterprise: custom (SCIM, white-labeling, HIPAA). - AI add-on on paid plans. **Editor:** Block-based, integrated with tasks/lists — turn docs into tasks inline. **Public publishing:** Public share links; custom domain via higher tiers; weak SEO for public docs. **Permissions:** Granular (list/task/doc), SSO on Business. **Integrations:** 1000+ (Slack, GitHub, Figma, Zoom, email, etc.). **Import/export:** Import from Asana, Trello, Jira, Monday, Basecamp, Wrike, Todoist, CSV. Export Docs to PDF; API. **Company health:** San Diego, Series C $400M (2021) at $4B valuation. Had public layoff news ~2023 (~10% cut), has since been steady (C3 — verify against trueup.io). **Killer features:** Task integration, very generous free tier, broad feature set. **Weaknesses:** Feature bloat / "ClickUp fatigue" meme, performance historically sluggish, docs feature less polished than Notion/Coda standalone. **Customers:** Reported 2M+ users, logos include Samsung, Ubisoft, IBM (C3 marketing). --- ## 13. Fandom / Wikia (community/fan wikis — special case) **Pitch:** Free wiki hosting for fan/community communities; monetizes via ads on fandom.com. Target: fan communities (gaming, anime, TV, movies). **Pricing:** Free for creators/readers. Fandom monetizes exclusively via advertising. **Editor:** MediaWiki-derived (UCP — "Unified Community Platform"), with a simplified visual editor. Heavy UX overhead vs. plain MediaWiki. **Public publishing:** All wikis are public on `.fandom.com` subdomains. **No custom domain option.** SEO is *extremely* strong because Fandom's domain has 20+ years of link equity — this is both the attraction (free traffic) and the trap (you can't take the SEO with you). **Scale (C2, [about.fandom.com](https://about.fandom.com/news/roblox-jumps-to-1-with-a-perfect-100-in-fandoms-2025-franchise-factor-score), [similarweb](https://www.similarweb.com/website/fandom.com/)):** 350M+ monthly unique visitors, 50M pages, 250,000 wiki communities, ~100,000 active contributors, 32M edits in 2025. **Permissions:** Wiki admins, bureaucrats, stewards, Fandom staff override. **Integrations:** Discord, Twitter feeds; minimal compared to workplace tools. **Import/export:** MediaWiki XML dumps available (critical — this is how communities migrate out). Fandom has historically made this harder/slower but has not blocked it. **Company/controversy context (C2):** - Fandom acquired Gamepedia (Twitch/Curse) in 2018, consolidating gaming-wiki market. - Aggressive ad monetization (auto-playing video, sponsored content, interstitials) has triggered a multi-year community revolt. In November 2025 Fandom even began showing ads to **logged-in non-editing users** ([thegameofnerds.com/2025/11/15](https://thegameofnerds.com/2025/11/15/the-monetization-backlash-how-fandom-wiki-sites-are-losing-community-trust/)). - **Major communities that forked off Fandom** (C2, [minecraft.wiki/Moving from Fandom](https://minecraft.fandom.com/wiki/Minecraft_Wiki:Moving_from_Fandom), [gamesradar](https://www.gamesradar.com/hollow-knight-silksong-community-follows-wow-minecraft-and-fallout-as-it-abandons-its-wiki-over-advertising-frustrations/)): - 2018: RuneScape - 2022: Zelda, Terraria - 2023: Minecraft, Fallout, Hollow Knight, WoW, Pizza Tower, Dead Cells - 2024: South Park, Dead by Daylight, League of Legends - 2025: Warframe, Vampire Survivors, Undertale/Deltarune, Nichijou, Balatro - 2025+: GTA wiki announced migration ahead of GTA 6 ([kotaku.com](https://kotaku.com/gta-wiki-leaving-fandom-rules-censorship-ads-videos-ditching-2000679115)) - CEO Perkins Miller resigned October 2025; Jay Sullivan appointed CEO February 4, 2026 (C2, [techbuzz.ai](https://www.techbuzz.ai/articles/fandom-ceo-perkins-miller-steps-down-after-six-tumultuous-years)). **Killer features:** SEO dominance, distribution/discoverability, brand recognition, zero infra cost for creators. **Weaknesses:** Ads, ads, ads. Domain lock-in (Fandom keeps the URL even after community forks — Fandom often maintains "ghost wikis" that outrank community's new home in Google, discussed extensively in the Minecraft wiki moving docs). Community control is limited by Fandom staff override policies. **Notable wikis (still on Fandom):** Roblox Wiki (#1 2025 franchise per Fandom's own ranking), Harry Potter, Star Wars, Marvel Cinematic Universe, Super Mario. --- ## 14. Miraheze / WikiTide Foundation (hosted MediaWiki, non-profit) **Pitch:** Free, ad-free, non-profit MediaWiki hosting. Target: communities that want full MediaWiki power without running servers, and without Fandom's ads. **Pricing:** Free. Funded by donations only ([meta.miraheze.org/Fundraiser](https://meta.miraheze.org/wiki/Special:MyLanguage/Fundraiser), C1). 2026 server target: ~$25,000/year. **Editor:** Full MediaWiki (wikitext + VisualEditor). Running MediaWiki 1.45.1 as of 2025/2026. **Public publishing:** Wikis at `.miraheze.org` by default; **custom domains supported free**. **Permissions:** Full MediaWiki rights system, user groups, stewards. **Integrations:** MediaWiki extension ecosystem (~200+ available), not SaaS-workplace style. **Import/export:** Full MediaWiki XML, Special:Export/Import; extremely portable. **Company/governance:** - Originally Miraheze (founded 2015). - In 2023 a faction forked "WikiTide" due to internal governance dispute. - **In March 2024 they merged back** under the Miraheze brand, with a new 501(c)(3) **WikiTide Foundation** as the governing body (C2, [mediawiki.org/Miraheze](https://www.mediawiki.org/wiki/Miraheze), [meta.miraheze.org/WikiTide Foundation/Merger FAQ](https://meta.miraheze.org/wiki/WikiTide_Foundation/Merger_FAQ)). - ~20,000 wikis hosted. **Killer features:** Zero ads, non-profit, full MediaWiki extension support, free custom domain. **Weaknesses:** Small operational team, funding reliant on donations (lean budget), uptime has had incidents historically. No SLA. **Notable wikis:** Many niche community wikis, some forks from Fandom use Miraheze when not going to wiki.gg. --- ## 15. wiki.gg and Fextralife (gaming-wiki challengers) ### wiki.gg **Pitch:** Gaming-focused wiki hosting by ex-Gamepedia staff; "editors-first"; light ads. Target: gaming communities leaving Fandom. **Pricing:** Free to communities. Monetized via ads (header/footer/right sidebar only — no in-article, no autoplay video) per [support.wiki.gg/wiki/Ads](https://support.wiki.gg/wiki/Ads) (C1). **Editor:** Full MediaWiki (it's literally a hosted MW farm). **Public publishing:** `.wiki.gg` subdomains; custom domains not standard. **Company (C2):** - Founded and staffed by former Gamepedia employees who were unhappy after Fandom's 2018 acquisition. - Operated by **indie.io**, a for-profit arm of Freedom Games (gaming publisher), PE-backed. Not community-owned. - Hosts ~800 wikis including the **official Terraria wiki**, Hollow Knight wiki, and many others that forked from Fandom. - "If you decide to leave, we will not compete with your community" — explicit anti-Fandom-ghost-wiki stance (C2, per their policy discussions). **Killer features:** Light, contained ad model; ex-Gamepedia operational expertise; pro-migration posture vs. Fandom; very popular forking destination. **Weaknesses:** Still ad-supported (though light); governance is a PE-backed for-profit; gaming-only (not a good fit for non-gaming communities). ### Fextralife **Pitch:** Soulsborne-era game guide wikis (Dark Souls, Elden Ring, Bloodborne) with forums and Twitch streams. Ad-supported. **Public reputation (C2):** - **Widely criticized for aggressive ads and pop-ups** — complaints date back years, still current ([fextralife forums threads](https://fextralife.com/forums/t66/getting-rid-of-the-ads), [HN 2024 thread](https://news.ycombinator.com/item?id=41799036)). - Accused by streamers (Asmongold, Penguinz0) in 2023 of artificially inflating Twitch viewership via embedded streams ([hype.my](https://hype.my/gaming-wiki-page-fextralife-takes-fire-from-streamers-for-shady-practises/), [raiderking](https://raiderking.com/penguinz0-accuses-fextralife-of-inflating-twitch-viewership/)). - Guide-page accuracy complaints persist. - SEO-wise it ranks extremely well for Souls-likes. **Killer features:** SEO dominance for specific game niches; integrated forums. **Weaknesses:** Ad UX (arguably worse than Fandom in some user reports); trust/reputation damage from 2023 controversies; single-proprietor feel vs. community ownership. --- ## 16. Archbee **Pitch:** Developer-docs SaaS with AI writing, API docs, in-app widget. Target: small dev teams documenting products/APIs. **Pricing (C2, [featurebase.app/blog/archbee-pricing](https://www.featurebase.app/blog/archbee-pricing), [docsie.io](https://www.docsie.io/blog/articles/archbee-vs-notion-pricing-comparison-2026/)):** - **No free plan**, 14-day trial. - Growing: $50/mo base for up to 3 users. - AI Write Assist: +$20/mo add-on. - Insights analytics: +$80/mo. - App Widget embed: +$80/mo. - Public API access: +$80/mo. - Typical real-world pricing: $150-230/mo once essentials are bundled in. **Editor:** Block WYSIWYG + Markdown, built for API docs (OpenAPI render, code blocks, diagrams). **Public publishing:** Custom domain, branded portal. **Permissions:** Role-based, SSO on higher tiers. **Integrations:** Slack, Intercom, GitHub, OpenAPI/Swagger, Segment, Zapier. **Import/export:** Markdown import/export, OpenAPI import. **Company health:** Small Romanian/US-based startup. Modest funding, appears stable but not a market leader (C3). **Killer features:** API-docs first-class rendering, in-app widget, reasonable dev-docs opinion. **Weaknesses:** Add-on pricing model inflates cost fast; GitBook covers similar ground with stronger Git workflow. --- ## 17. Stonly and BetterDocs (tangential KB platforms) ### Stonly **Pitch:** Interactive step-by-step guides and decision trees for support/onboarding — a different shape from traditional article KBs. **Pricing (C2, [stonly.com/pricing](https://stonly.com/pricing)):** Basic: 400 guide views/mo, 5 published guides, 1 team member. Custom pricing for bigger. Not a per-seat flat rate — usage-based. **Editor:** Guide builder (branching step flows), article editor, AI answers. **Public publishing:** Yes — embeddable widgets + standalone KBs, custom domain. **Audience:** Customer-support and ops teams wanting decision-tree troubleshooting in addition to (or instead of) article KBs. **Killer features:** Interactive branching guides with analytics on drop-off; in-app widgets; triggered knowledge delivery. **Weaknesses:** Narrow use case — not a general team wiki; less useful for pure long-form articles. ### BetterDocs **Pitch:** WordPress plugin for adding a knowledge-base to a WP site. **Not SaaS in the usual sense — you self-host on WordPress.** Included here because the question asked. **Pricing (C2, [betterdocs.co](https://betterdocs.co/)):** - Free plugin (WordPress.org). - Premium: ~$69/year (1 site) / $149/year (unlimited sites) / $299/year (agency lifetime). - AI-enabled tier ~$239/year. **Editor:** WordPress Gutenberg blocks + Elementor widgets. **Public publishing:** Via your WordPress site; custom domain is whatever WP runs on. **Integrations:** WordPress ecosystem (WooCommerce, Dokan), AI chatbots. **Killer features:** Cheap, owns your data (it's in your WP DB), leverages WP SEO plugins. **Weaknesses:** You run WordPress (not "hosted SaaS" in the true sense — you still need a WP host/infra). --- ## Cross-cutting observations ### SEO quality ranking for public KBs (rough, C3) 1. **Strongest:** Fandom (pure domain equity), Document360, GitBook, HelpJuice, wiki.gg, Miraheze 2. **Moderate:** Slab, Nuclino Business, Archbee, Confluence (via proxy apps) 3. **Weak default:** Notion, Coda, ClickUp Docs, Slite (patchable via third-party layers like Super.so/Feather for Notion, but that's extra cost + setup) ### Lock-in / portability ranking (rough, C3) - **Easiest to leave:** GitBook (Git Sync = your content is Markdown in your repo), Miraheze (MediaWiki XML), Nuclino/Slite (Markdown export), BetterDocs (it's just your WordPress DB). - **Middle:** Slab, Document360, HelpJuice, Tettra (clean MD/HTML exports). - **Hardest:** Coda (formulas/buttons/Packs don't export), Notion (relations/formulas/rollups lost on export), Confluence (macro fidelity issues), Fandom (they keep the domain and the SEO). ### Stability / company-risk ranking (rough, C3) - **Rock-solid:** Atlassian (Confluence) — public company, $4B revenue. - **Strong:** Notion (~$500M ARR, $11B secondary), Fandom (massive traffic but corporate turmoil — CEO change, monetization backlash), Kovai/Document360 (bootstrapped profitable), Grammarly (owns Coda). - **Stable-but-small:** GitBook (~$3.9M rev, 35 employees, but profitable), Slite (~$5.5M rev), Nuclino (bootstrapped), Tettra (GSoft-owned). - **Single-point-of-failure risk:** Slab (no funding since 2018, ~11-50 employees), Archbee (small). - **Non-profit:** Miraheze (depends on donations; ~$25K/yr server budget — thin). - **Turmoil:** Fandom (ad-model backlash, CEO exit Oct 2025, new CEO Feb 2026). --- ## C5 / Unknowns and caveats - **Exact 2026 pricing** for Document360 (sales-led, no published list) and Guru Enterprise. - **Coda post-acquisition roadmap** — whether Grammarly will keep Coda as a standalone product long-term is unclear as of 2026-04. - **Fandom future ad policy** under Jay Sullivan (CEO Feb 2026) — too new to evaluate. - **HelpJuice customer logos** (Amazon, Hertz, Virgin) — marketed but not independently verified; customer lists on vendor sites are generally C3/C4 without case-study confirmation. - **Many "2026 pricing guide" articles are AI-generated SEO pages** with recycled/stale data (featurebase.app, docsie.io blog). Pricing claims here that originated from those aggregators are C2 at best; **C1 verification requires the vendor's own /pricing page**, which was not exhaustively re-fetched for every tool here. - **Stonly Basic-tier price** — could not pin down exact $/mo figure for the named "Basic" plan; site uses "custom pricing" language even for SMB. ### Failed / thin searches - Fextralife post-2023 news (mostly older complaints; little recent coverage). - Notion layoff history — Blind posts exist but no confirmed 2024-2026 layoff round surfaced. - Archbee funding/runway — sparse public info. --- ## Sources (select — full URLs inline above) - [notion.com/pricing](https://www.notion.com/pricing), [notion.com/help/export-your-content](https://www.notion.com/help/export-your-content) - [gitbook.com/pricing](https://www.gitbook.com/pricing), [gitbook.com/features/git-sync](https://www.gitbook.com/features/git-sync) - [atlassian.com/software/confluence/pricing](https://www.atlassian.com/software/confluence/pricing) - [slab.com/pricing](https://slab.com/pricing/) - [getguru.com/pricing](https://www.getguru.com/pricing) - [tettra.com/pricing](https://tettra.com/pricing/) - [slite.com/pricing](https://slite.com/pricing) - [document360.com/pricing](https://document360.com/pricing/), [YourStory Dec 2025](https://yourstory.com/2025/12/kovaicos-document360-crosses-10m-arr-eyes-25m-by-2028) - [helpjuice.com/pricing](https://helpjuice.com/pricing) - [nuclino.com/pricing](https://www.nuclino.com/pricing) - [coda.io/pricing](https://coda.io/pricing), [G2 Grammarly Coda](https://www.g2.com/products/grammarly-coda/reviews) - [clickup.com/pricing](https://clickup.com/pricing) - [about.fandom.com](https://about.fandom.com/), [minecraft.fandom.com/Moving from Fandom](https://minecraft.fandom.com/wiki/Minecraft_Wiki:Moving_from_Fandom), [kotaku.com GTA migration](https://kotaku.com/gta-wiki-leaving-fandom-rules-censorship-ads-videos-ditching-2000679115), [techbuzz.ai CEO exit](https://www.techbuzz.ai/articles/fandom-ceo-perkins-miller-steps-down-after-six-tumultuous-years), [thegameofnerds.com](https://thegameofnerds.com/2025/11/15/the-monetization-backlash-how-fandom-wiki-sites-are-losing-community-trust/) - [miraheze.org](https://miraheze.org/), [meta.miraheze.org Merger FAQ](https://meta.miraheze.org/wiki/WikiTide_Foundation/Merger_FAQ), [mediawiki.org/Miraheze](https://www.mediawiki.org/wiki/Miraheze) - [wiki.gg](https://www.wiki.gg/), [support.wiki.gg/Ads](https://support.wiki.gg/wiki/Ads) - [fextralife forums](https://fextralife.com/), [HN thread on Fextralife](https://news.ycombinator.com/item?id=41799036) - [featurebase.app/blog/archbee-pricing](https://www.featurebase.app/blog/archbee-pricing) - [stonly.com/pricing](https://stonly.com/pricing) - [betterdocs.co](https://betterdocs.co/)
