Features included source control, code assist, refactoring, debugging, WEBrick servers, generator wizards, syntax highlighting, data tools, and much more.
During that time, the three developers worked as co-ops from the Rochester Institute of Technology at IBM Rational in Raleigh, NC.
In November 2006, Kyle Shank and Matt Kent began working on an idea for a startup company, which would eventually become Persai.
Kyle met with Aptana founder Paul Colton at EclipseCon 2007, and it became clear that handing over the project would be in the best interests of the RadRails community.
RadRails 1.0 was released under an open source license on March 13, 2008, as a plug-in to Aptana Studio, an Eclipse-based IDE for Web and Ajax development that can run either standalone or within Eclipse.
