Short answer: the right GitBook alternative depends on why you're leaving. Here are the picks by reason. Every price was checked on the vendor's own pricing page on 2 November 2026.
| If you're leaving GitBook because… | Pick | Starting price |
|---|---|---|
| Per-site plus per-user pricing is adding up, or you want your AI agent to write the docs | Dokly | Free; paid from $29/mo flat |
| You want more design polish and docs-as-code, and budget isn't the issue | Mintlify | Free; Pro $450/mo (annual) |
| You want $0 licences and full control, with an engineer to run it | Docusaurus | Free (open source) |
| Your docs are mostly API reference and you want a developer hub | ReadMe | Free; Pro $250/mo (annual) |
| You want product docs and internal docs in one tool | Archbee | From $80/mo |
| You need editorial review workflows and governance | Document360 | Quote only |
| You mostly need an internal wiki | Notion | Free; Plus $10/member/mo |
| You're an open-source project on Sphinx or MkDocs | Read the Docs | Free for OSS |
I build Dokly, so read the Dokly entry with that in mind. I've also written down where GitBook is still the better choice, because for some teams it is.
What GitBook costs in 2027#
GitBook prices each site separately, then adds a fee per user. As of 2 November 2026:
- Free: one user, with Git Sync, llms.txt and an MCP server included.
- Essential: $65 per site per month plus $12 per user, billed annually. Adds a custom domain, the "Ask" mode of GitBook Assistant, and metered auto-translation.
- Ultimate: $249 per site per month plus $12 per user. Adds Assistant chat and AI Insights.
- Enterprise: custom. SAML SSO is only here.
That model is fine for one site and a handful of editors. It gets expensive when you run several sites (docs, a help center, a developer portal, a changelog), because each one carries its own fee. Five sites on Essential with one user is $337 a month before anyone else joins.
When to stay on GitBook#
Be honest with yourself before you migrate. GitBook is still the better pick if:
- You rely on two-way Git sync. Writers in the browser and engineers in the repo, both staying in step. GitBook does this better than anyone on this list, and it's on the Free plan.
- You need translations now. GitBook's auto-translation is the most accessible in the category.
- You need a reader-facing AI assistant. GitBook has one; several alternatives don't.
- You have many editors on one site. Per-user pricing hurts less when the site count is low.
If none of those is why you're here, read on.
1. Dokly#
Best for: teams running more than one docs site, or teams that want their own AI agent to keep docs current.
Dokly is a hosted docs platform with a visual editor that writes MDX underneath. No repo needed, nothing to build. You get a subdomain on signup and your own domain from the Starter plan.
The difference from GitBook is how AI fits in. Instead of a built-in AI writer, your own agent writes to Dokly over MCP, and you approve every change as a diff. Ask Claude Code or Cursor to document the feature you just merged; the edit lands as a proposal, and new pages arrive as drafts. Dokly doesn't meter the agent's writes.
What you get:
- Visual MDX editor with components (callouts, tabs, steps, code groups)
- A docs layout or a help-center layout with a search-first homepage
- Auto-generated
llms.txt - One-way GitHub sync: Markdown in a repo folder publishes on every push
- OpenAPI import and an interactive API playground on Team
Pricing (2 Nov 2026): Free for one site with unlimited pages. Starter $29/mo (one site, custom domain, no analytics). Team $99/mo (five sites, analytics, API playground). Business $199/mo. Flat, no per-user fees.
Against GitBook: one site with a custom domain is $29 on Dokly Starter versus $77 on GitBook Essential with one user. Five sites is $99 on Dokly Team versus $337+ on Essential.
When not to pick Dokly: if you need two-way Git sync, translations, a reader-facing AI assistant, or multi-editor workspaces with roles. Dokly doesn't have those yet. More detail in Dokly vs GitBook.
2. Mintlify#
Best for: developer-tool companies that want the most polished docs-as-code setup and will pay for it.
Mintlify keeps your docs as MDX in your Git repo, with a web editor on top. Its sites look excellent out of the box, and its reader-facing AI Assistant is strong.
Pricing (2 Nov 2026): Starter is free. Pro is $450/mo billed annually, or $540/mo monthly. The Assistant is metered: 10,000 AI credits a month on Pro, then $0.01 per credit, at about 25 credits an answer.
Against GitBook: Mintlify has more design polish and a deeper MDX component library. It's also more expensive and more tied to Git.
When not to pick it: if cost is why you're leaving GitBook. See Mintlify vs GitBook.
3. Docusaurus#
Best for: teams with a front-end engineer who want full control and no licence fees.
Meta's open-source static site generator is React-based and MDX-native, with versioning and i18n built in. You host it wherever you like.
Pricing: free. The cost is engineering time: setup, search, hosting, upgrades, and every edit going through a pull request.
Against GitBook: total control and no per-user bill. But non-engineers lose the visual editor.
When not to pick it: if product, support or marketing people need to edit docs. See Docusaurus vs GitBook.
4. ReadMe#
Best for: API-first companies whose docs are mostly reference.
ReadMe builds an interactive API reference from your OpenAPI spec, adds guides and a changelog, and shows which endpoints developers actually call.
Pricing (2 Nov 2026): Starter is free. Pro is $250/mo billed annually. Enterprise is contact-sales.
Against GitBook: a much stronger API reference and developer analytics. Weaker for general product docs.
When not to pick it: if most of your pages are guides rather than endpoints. See API documentation tools.
5. Archbee#
Best for: teams that want public product docs and internal docs in one tool.
Archbee has a block editor that feels close to GitBook's, plus API reference and internal spaces.
Pricing (2 Nov 2026): Growing from $80/mo. Scaling from $350/mo. Enterprise is custom. Startups can get 50% off for two years.
Against GitBook: a similar editing experience with flat team pricing. Smaller ecosystem.
When not to pick it: if you only need public docs. See Archbee vs GitBook.
6. Document360#
Best for: writer-led teams that need review workflows, versioning and access control.
Document360 is built for process: draft, review, approve, publish, across multiple languages and public, private or mixed knowledge bases.
Pricing (2 Nov 2026): quote only, based on editors, workspaces and languages.
Against GitBook: stronger governance and knowledge-base features. Heavier to adopt.
When not to pick it: if you're a small team that wants to publish this week.
7. Notion#
Best for: teams whose "docs" are really an internal wiki.
Notion is the nicest writing tool on this list, and fine for internal knowledge.
Pricing (2 Nov 2026): Free. Plus $10 per member per month. Business $20 per member per month.
Against GitBook: a better workspace for notes and specs. A much weaker public docs site: thin navigation, no versioning and little SEO control.
When not to pick it: for customer-facing docs. See GitBook vs Notion.
8. Read the Docs#
Best for: open-source projects on Sphinx or MkDocs.
Read the Docs builds and hosts docs from your repo on every commit, with a version per branch or tag.
Pricing (2 Nov 2026): free for open-source projects. Business plans are $50, $150 and $250 per month.
Against GitBook: free for OSS and very reliable. No visual editor.
When not to pick it: for a commercial product where design and non-engineer editing matter.
GitBook alternatives comparison table#
| Tool | Pricing model | Paid from | Visual editor | Git sync | How an AI agent writes |
|---|---|---|---|---|---|
| GitBook | Per site + per user | $65/site + $12/user | Yes | Two-way | MCP server on every plan |
| Dokly | Flat per plan | $29/mo | Yes (MDX) | One-way (Git to Dokly) | Over MCP, as diffs you approve |
| Mintlify | Flat per plan | $450/mo | Web editor | Yes | Admin MCP; saves open a PR |
| Docusaurus | Free (self-hosted) | $0 | No | Repo is the source | Through your repo |
| ReadMe | Flat per plan | $250/mo | Yes | Optional | Not advertised |
| Archbee | Flat per plan | $80/mo | Yes | Optional | Not advertised |
| Document360 | Quote | Quote | Yes | No | Not advertised |
| Notion | Per member | $10/member | Yes | No | Not advertised |
| Read the Docs | Flat per plan | $50/mo | No | Repo is the source | Through your repo |
"Not advertised" means the vendor's site didn't describe a way for your own agent to write changes for review when we checked.
How to migrate off GitBook#
- Export to Markdown. Turn on GitBook's Git Sync and let it write your content to a GitHub repo. That gives you a full Markdown copy you own.
- Convert GitBook blocks. Hints, tabs and embeds are stored as
{% %}tags. Map them to your new tool's components (in Dokly, callouts and tabs). - Import. With Dokly, point GitHub sync at the folder, or paste pages into the editor. Docusaurus, Mintlify and Read the Docs read the repo directly.
- Keep your URLs. Match the old paths where you can and add 301 redirects where you can't, or you'll lose rankings.
- Check your agent setup. Make sure
llms.txtis live on the new site and reconnect any MCP clients your team used.
A small docs site usually moves in an afternoon. Large sites with many custom blocks take longer, mostly in step 2.
Frequently Asked Questions#
What is the best GitBook alternative?#
It depends on why you're leaving. For flat pricing across several sites, or an AI agent that writes while you approve diffs, Dokly. For maximum polish and docs-as-code, Mintlify. For free and self-hosted, Docusaurus. For API-heavy docs, ReadMe.
Is there a free GitBook alternative?#
Yes. Docusaurus is free and open source, Read the Docs is free for open-source projects, and Dokly, Mintlify, ReadMe and Notion all have free plans. Dokly's free plan includes one site with unlimited pages.
Is GitBook still free?#
Yes, for one user. The Free plan includes Git Sync, llms.txt and an MCP server. A custom domain and more users need Essential, which is $65 per site per month plus $12 per user on annual billing.
Why is GitBook so expensive?#
Because it charges per site and per user. A team with one site and a few editors pays a reasonable amount; a team with several sites pays each site's fee again. Its reader-facing AI chat and AI Insights also require the Ultimate plan at $249 per site.
Can I move from GitBook without losing SEO?#
Yes. Keep the same URL paths where possible, add 301 redirects for any that change, and submit the new sitemap in Google Search Console. Rankings usually settle within a few weeks.
Final thoughts#
GitBook is still a good product, and for teams that live on two-way Git sync it may be the best one. But per-site pricing punishes teams that run more than one docs property, and the biggest change for 2027 is that your docs increasingly get written by agents. Pick the tool that lets that happen safely.
If you want flat pricing and an agent that drafts while you approve, try Dokly free. One site, unlimited pages, no card.
