GitBook alternatives
If you like GitBook’s block editor but not its per-site-plus-per-seat pricing or its closed platform, the closest alternative is Nibleaf: an open-source docs platform with a Notion-style editor over plain Markdown, free while in beta and free forever self-hosted — we build it, and its gaps are listed below. Docusaurus and Starlight are the strongest free static-site options, Scalar is the API-first pick, and Mintlify is the closest hosted-SaaS equivalent.
Nibleaf is an open-source, self-hostable documentation platform — an alternative to Mintlify and GitBook — with a Notion-style WYSIWYG editor over plain Markdown, first-class Arabic/RTL support, custom domains, and a free cloud beta at nibleaf.com.
We build Nibleaf, so read this page as an informed but interested party: every price was checked against the vendor’s official pricing page as of July 2026 and links to its source, and everything Nibleaf doesn’t do yet is disclosed plainly.

Nibleaf
Our productNibleaf is an open-source, self-hostable documentation platform — an alternative to Mintlify and GitBook — with a Notion-style WYSIWYG editor over plain Markdown, first-class Arabic/RTL support, custom domains, and a free cloud beta at nibleaf.com. Full disclosure: Nibleaf is our product — and compared to GitBook it does not yet have an OpenAPI playground, two-way git sync, reader authentication, or SSO/SAML. The roadmap is public on GitHub.
Best for: Teams that want an open-source, self-hostable docs platform with a WYSIWYG Markdown editor and first-class Arabic/RTL.
Free, MIT-licensed static site generator from Meta. Write MDX in your repo, embed React components, and get versioning and i18n (including RTL locales) out of the box; you build and host the output yourself.
Best for: Developer teams that want docs-as-code with full control of a React codebase.
Free, open-source documentation theme built on Astro. Markdown, Markdoc, or MDX in; a fast static site with search, i18n, and dark mode out.
Best for: Fast static docs sites with minimal setup, especially if you already like Astro.
API-first documentation: interactive references generated from OpenAPI/AsyncAPI documents, Markdown/MDX guides, and two-way git sync. Its API client is open source, and hosted plans are available.
Best for: Teams whose documentation is primarily an API reference.
Hosted documentation platform with a generous free Starter plan (custom domain, web editor, API playground) and paid Pro/Enterprise plans that add AI features, preview deployments, and SSO, as of July 2026.
Best for: API-heavy startup docs where AI tooling and an API playground matter most.
