Ruby-Doc.org

Fast, searchable Ruby documentation for core and standard libraries, plus links to related

Visit Ruby-Doc.org

Ruby-Doc.org is a community documentation project that publishes API reference material for the Ruby programming language. It addresses the need to look up core classes, modules, and included libraries in documentation that matches the Ruby version a project uses, with links to tutorials, guides, books, and related sites.

The site organizes API documentation by version, covering releases from Ruby 1.8.6 through Ruby 4.0.6. Each release entry provides complete API documentation, while some older versions are split into separate core and standard library sections. The homepage also links to release notes for Ruby 3.4, along with sections for current downloads and learning resources.

Ruby-Doc.org is aimed at Ruby developers and learners consulting reference material for a specific release. The pages describe no paid plans, trials, editions, or seat-based or usage-based packaging; the documentation is presented as a community project.
