A Development Tool for Ruby

Mondrian is a cross-platform project-manager and editor for the Ruby language. Written in 100% native Ruby using the FOX GUI toolkit, Mondrian has the familiar look and feel of a modern IDE while remaining dedicated to the uniqueness of the Ruby language and its community. Some features include:
  • a dynamic object browser
  • runtime error integration
  • a full-featured project manager
  • syntax highlighting
  • runs identically on Windows and Linux

Have questions not answered here? Check out the forums to talk with others about Mondrian, or feel free to email us directly.

We believe that a flexible, easy-to-use IDE helps make programming more fun, and will help convince new programmers to choose Ruby over less friendly languages. Please contact us with any suggestions on how we can improve your experience, or to tell us about features of your favorite editor you wish you could use with Ruby.
