TomatoUSB at this time is actively developed through community contributions in the form of several "mods". Please see the mods page for more information.

Tomato USB is an Open Source project. If you would like to participate in the development, feel free to check out the source code from the Git Repository (if you're not familiar with Git, this Crash Course may help to get you started), and submit us your patches, or post the bug reports and your suggestions on the forum.

As a Linux-based firmware for WLAN routers, Tomato USB has a lot in common with many similar projects. We would like to thank the developers of those projects for sharing their ideas and making the source code available, which greatly helps us to continuously improve Tomato USB!
