The JetBrains team regularly updates RubyMine with new features based on changes in Ruby itself. For complex web application development projects with multiple developers, the productivity gains often outweigh the cost.
Is Visual Studio Code good for Ruby developers?
VS Code has become extremely popular among Ruby developers for good reasons:
- Free and open-source with frequent updates
- Lightweight compared to full IDEs but still powerful
- Extensive marketplace for Ruby-specific extensions:
- Ruby
- Ruby Solargraph (for intelligent code completion)
- Ruby Test Explorer
- Endwise (for automatically adding
endstatements) - Ruby Linter
The editor provides excellent code navigation capabilities and integrates well with Git workflows. Its popularity extends beyond Ruby, making it ideal for full-stack developers who work with multiple languages. According to the 2023 State of DevOps integration report, VS Code is now used by 68% of organizations that deploy Ruby applications.
What features should I look for in an IDE for Ruby?
When evaluating Ruby programming IDEs, prioritize these features:
- Ruby syntax highlighting and code formatting
- Intelligent code completion for Ruby and installed gems
- Debugging capabilities with breakpoints and variable inspection
- Integration with version control systems like Git
- Support for Ruby test frameworks (RSpec, Minitest)
- Ruby bundler integration for dependency management
- Project management tools for organizing files
- Code navigation to quickly find methods and classes
- Ruby linting tools integration
- Terminal access with Ruby interpreter support
For Ruby on Rails developers, additional features like view/controller navigation, database schema visualization, and Rails-specific generators add significant value.
Can I use Sublime Text for Ruby development?
Sublime Text works excellently for Ruby development with the right setup:
- Fast startup and responsive even with large files
- Minimal UI that maximizes coding space
- Package Control gives access to Ruby-specific tools:
- SublimeCodeIntel for completion

While not as feature-complete as RubyMine out of the box, its speed and efficiency make it popular for quick edits and smaller projects. The $99 one-time license fee makes it more accessible than subscription-based options.
Are there free IDEs available for Ruby?
Several high-quality free options exist for Ruby development:
- Visual Studio Code: The most popular free option with excellent extension support
- Atom: GitHub’s editor with good Ruby support (though now deprecated)
- Vim/Neovim: Powerful terminal-based editors with strong Ruby syntax plugins
- Emacs: Highly customizable editor with robust Ruby mode
- NetBeans: Complete IDE with Ruby support
- Eclipse with Ruby plugins: Good for Java developers transitioning to Ruby
According to the Ruby Toolbox survey, about 65% of Ruby developers now use free code editors rather than paid IDEs. The gap in functionality has narrowed significantly with the maturity of extensions and plugins for these free options.
How does Atom compare for Ruby development?
While GitHub has deprecated Atom in favor of VS Code, it deserves mention:
- Clean interface with good Ruby syntax highlighting
- Packages like “language-ruby” and “ruby-block”
