Open Source

GtkRadiant is on GitHub where it can easily be forked and modified to suit the specific and advanced needs of development teams, submit a pull request for a patch, or report an issue.

Cross Platform

GtkRadiant runs on Windows, Mac and Linux platforms. It supports a number of games powered by id Tech engines, supporting both commercial developers and individual modders.

Community Supported

By the community, for the community. GtkRadiant is developed and tested by volunteers, and offers a number of community support options populated by like-minded game developers.

Mission Statement

GtkRadiant is a very old project. There have been many versions over the years, and lots of contributors. In the early 2000's it supported many id Tech 3 games, and even some id Tech 4 games. Responsibilities and interests have shifted a lot around this project, but I think most people will recognize me as the person most consistently involved with the editor over the years.

Now that I have left id, I had some time to sit back and look at all the games based on id Tech that I enjoy playing, and at the level design community around them. I figured it would make sense to resume some maintenance efforts for the benefit of those projects.

We are a small group of developers involved in this 'rebirth' of GtkRadiant, and in the spirit of the above I'd like to call out a few rules that we should try to stick to for this project:
