Alternatives to Read the Docs
The long-running Sphinx and MkDocs hosting
Read the Docs ranks #5 of 9 in Documentation site generators, with an Alt Score of 81. It is licensed under MIT, freemium from $50/month and available on the web. 12 of 12 checklist rows are verified against a public source.
Open-source maintainers and software teams who write documentation in tools like Sphinx or MkDocs and want it built and published automatically from their Git repository, without managing their own hosting or build infrastructure.
Automated builds and hosting for documentation on every commit or pull request, with versioned docs that track your product releases. It includes PR preview builds, search, access control (including SSO for private docs), and analytics/traffic data for your docs site.
You connect a Git repository (GitHub, GitLab, Bitbucket) and add a YAML config file describing the build environment and doc tool. Read the Docs then builds the docs automatically on each push and serves the result at a hosted URL, keeping multiple versions available side by side.
