About RubyMine

RubyMine is an integrated development environment from JetBrains for Ruby and Ruby on Rails development, also supporting gem development without Rails. It provides context-aware code navigation, syntax highlighting, autocompletion, and refactoring tools, along with a graphical debugger for Ruby and JavaScript that supports breakpoints and incremental execution. The IDE includes a GUI-based test runner, built-in database tools, version control integration, SQL support, and Docker deployment capabilities without leaving the editor.

The product integrates AI features, including code completion, next-edit suggestions, code explanation, refactoring guidance, and commit message generation. It supports multiple AI models (Claude, GPT, Gemini, Grok, or local models) and multi-agent tools (Junie, Claude Agent, Codex, GitHub Copilot, Cursor via ACP), with usage available through JetBrains AI credits or the user's own AI subscriptions and API keys.

RubyMine supports Rails, RBS, Rake, Rubocop, Hotwire, RSpec, and Git, and incorporates web technologies from WebStorm and database tools from DataGrip. It is aimed at Ruby and Rails developers, from beginners to experienced teams, and is free for non-commercial use. JetBrains states the product is SOC 2 certified.
