RubyGems

RubyGems is the Ruby community gem hosting service and the canonical package registry for the Ruby programming language ecosystem, facilitating the discovery, installation, and publication of Ruby libraries known as gems. The platform has accumulated over 255 billion total downloads, serving the global Ruby developer community with instant gem publication, semantic version resolution, and dependency management through the Bundler integration. Operated by Ruby Central through its Open Source Program, the service is funded by community sponsorships, memberships, and infrastructure donations from organizations committed to keeping the Ruby ecosystem secure and sustainable. The platform infrastructure leverages Amazon Web Services for compute and storage, Fastly for global CDN distribution of gem files, DNSimple for DNS resolution, Datadog for infrastructure monitoring, Honeybadger for error tracking, and Mend.io for security scanning of published gems. The REST API provides programmatic access to gem metadata, version history, dependency trees, download statistics, and search functionality, enabling integration with CI/CD pipelines, security audit tools, and IDE plugins. The gem publishing workflow uses gem push commands with API key authentication, supporting yank for removing specific versions, owner management for transferring gem ownership, and Webhooks for notifying downstream services of new releases. Security features include mandatory multifactor authentication for gem owners, gem signing through RubyGems Security Policy, and automated vulnerability scanning through the Bundler Audit integration. The platform hosts gems from major Ruby projects including Rails, Sinatra, Hanami, Jekyll, Vagrant, Homebrew, Fastlane, CocoaPods, and thousands of community libraries across web frameworks, testing tools, database adapters, and developer utilities.
