About RBTools

RBTools is a set of command line tools and a rich Python API for use with Review Board.

These tools make it easy to post changes for review, keep them up-to-date, land reviewed changes, and test other people's changes in your own tree, check your workload, and much more.

When using RBTools, you'll do most everything through the rbt command, which supports a number of sub-commands, like post, diff, land, and patch.

Installing RBTools

We provide native installers for Windows and MacOS, along with Python packages for Linux and other platforms. See the RBTools Downloads page for downloads and installation instructions.

See the RBTools documentation for more information.

Using the Python API

The included Python API can be used to write scripts and applications that interface with Review Board, and can also be used to write new commands for RBTools.

There's very little that you can't do with the Python API. To learn more, see the RBTools Python API documentation and the Review Board API documentation.

Getting Support

We can help you get going with Review Board and RBTools, and diagnose any issues that may come up. There are two levels of support: Public community support, and private premium support.

The public community support is available on our main discussion list. We generally respond to requests within a couple of days. This support works well for general, non-urgent questions that don't need to expose confidential information.

We can also provide more dedicated, private support for your organization through a support contract. We offer same-day responses (generally within a few hours, if not sooner), confidential communications, installation/upgrade assistance, emergency database repair, phone/chat (by appointment), priority fixes for urgent bugs, and backports of urgent fixes to older releases (when possible).
