The Most Intelligent Ruby and Rails IDE

Ruby Development

JetBrains RubyMine IDE includes a comprehensive Ruby code editor aware of dynamic language specifics. It provides smart coding assistance, intelligent code refactoring, and deep code analysis capabilities. With easy project configuration, automatic Ruby Gems management, Rake support, and built-in consoles, it has everything a Ruby developer needs in a development environment.

Ruby on Rails

RubyMine brings dedicated RoR features including project structure views, quick Model-View-Controller navigation options, Rails-specific code completion, intention actions, and automated refactorings. All this, plus best-of-breed support for ERB, HAML and Slim editing, coupled with advanced web development tools and a built-in Rails console, is the best recipe for producing cutting-edge Web applications.

JavaScript & HTML/CSS

Speed and efficiency are guaranteed for your client-side and server-side development in JavaScript, CoffeeScript, TypeScript, HTML, CSS, Less or Sass, as RubyMine provides best-in-class coding assistance and a wide range of advanced features. Node.js, Dart, AngularJS and JavaScript testing frameworks are supported via free plugins. Enhance and streamline your debugging experience without leaving the IDE, thanks to JavaScript and Node.js debugging tools.


RubyMine brings all the essential productivity boosters to the world of RubyMotion apps. Code insight is available for Ruby, Objective-C and Java APIs, making iOS, OS X and Android development with RubyMotion even more pleasant. With a powerful testing and debugging UI, working either with a simulator or a real device, it is much easier to fine-tune your application code. All Rake commands and an interactive console are at your disposal as well.

Code Analysis & Refactorings

Let your IDE take care of your code. Smart, type-aware code completion, intelligent code inspections, live templates and intention actions all work together to help you code faster and fail-proof. Refactor your Ruby code the intelligent, language specific-aware way, with safe Rename and Delete, Extract Method, Introduce Variable, Inline Variable or Method, and more refactorings.


The value of testing should not be underestimated. Like writing code, unit-testing becomes second nature with RubyMine‘s flexible, well-thought-out RSpec, Cucumber, Shoulda, MiniTest and Test::Unit integration. Write tests quickly thanks to intelligent code completion and navigation, and easily run tests and analyze their results with a graphical UI.

A Powerful Debugger

Fine-tuning application code is an essential step in every software project. RubyMine‘s Ruby debugger inherits all the best from the proven IntelliJ IDEA Java/JSP debugger while focusing on the needs of Ruby and Rails developers. It allows breakpoints in Ruby, ERB and JavaScript code, and provides highly informative views like Console, Variables, Frames and Watches.
