6 free alternatives to Read the Docs

GitBook's free plan is built for an individual who wants to publish and edit documentation in one place. It includes access for 1 free user, unlimited page views, a block-based visual editor with Markdown support, GitHub or GitLab sync, preview deployments, full-text search, page analytics, change requests, version history, comments, integrations, imports from common formats, and basic roles. It also includes Google or email domain SSO for allowed email domains and email support. This is a broader editing and collaboration surface than a public-hosted doc site, even on the free plan.

• Beats Read the Docs: More complete editing and collaboration workflow
• Falls short: Only 1 free user
• Who should switch: Switch here if you are a solo doc owner who wants a richer authoring experience than a public hosting-only setup.

Bump.sh's free tier is aimed at API documentation teams that want structured portal publishing. It includes up to 10 API docs, up to 3 internal users, up to 20 external users or guests, support for OpenAPI, AsyncAPI, and OpenAPI Overlays, CLI and GitHub integration, a custom domain and logo, and documentation hubs. That makes it a good fit when your docs are API-first and you want a documented portal with some team access, not just a static public site. The free tier is more generous than a single-project setup if you are organizing several APIs.

• Beats Read the Docs: Supports multiple API docs and guest access
• Falls short: Requires a tighter doc count limit
• Who should switch: Switch here if your documentation is API-centric and you need a small portal with multiple docs.

GitHub Pages is an always-free static site host for content stored in GitHub. It includes one site per GitHub account or organization, unlimited project sites, custom domain support via a CNAME file, Jekyll-based blogging with Markdown support, and custom 404 pages with submodules support. For public docs that can be built as a static site, it removes the public-docs-only framing and does not add ads. It is simple, durable, and broad enough for many documentation sites that already live in GitHub.

• Beats Read the Docs: Unlimited project sites
• Falls short: No built-in docs platform features
• Who should switch: Switch here if you want the simplest always-free path for static documentation already maintained in GitHub.

Mintlify's free tier gives you access to the full platform, a custom domain, the web editor, the MCP server, custom components, and agent optimizations. It is designed for teams that want a modern documentation workflow with a hosted editor and AI-oriented features, while keeping the basic publishing stack free. The free tier is especially attractive if you want to author and manage docs in one product without stitching together multiple tools. It is not just hosting, it is a full documentation workspace from the start.

• Beats Read the Docs: Full platform access on the free tier
• Falls short: Less clearly scoped for open-source public hosting
• Who should switch: Switch here if you want a modern hosted docs workspace and do not want to start from a public-hosting-only model.

SimpleLocalize's free entry point is a short trial-style plan that includes 250 translation keys, unlimited strings, 10 projects, 10 languages, and 90 days of activity and history log. It is a better fit for localized product content than for general documentation hosting. If your main issue with Read the Docs is not docs publishing but managing translated content across projects, this gives you a translation workflow rather than a hosting-centric one. The free tier is narrower, but the project and language structure can matter more for localization work.

• Beats Read the Docs: Better for multilingual content workflows
• Falls short: It is a time-limited trial, not a perpetual docs host
• Who should switch: Switch here if your real need is localization management rather than documentation hosting.
