Aptana RadRails

Free, open source IDE for Ruby and Rails applications

RadRails is now included as part of Aptana Studio 3. No extra download required--now integrated into a single editor.

Core Capabilities

Code Assist

Quick access to Ruby, HTML, CSS and JavaScript structures, methods, elements, properties, tags & attributes. Helpful information about the element also shown. Supports your custom code as well.

Integrated Debugger

Set breakpoints, inspect variables, control execution. The integrated Ruby & Rails debugger helps you squash those bugs.


View and navigate the structures in your file using this hierarchical outline of your Ruby or HTML page. Select nodes to jump to that location in the editor. Filter nodes to see collections that match patterns.

“I'm really starting to like RadRails, especially as a plugin since it's nice to be able to use one IDE for everything I do.”
