Treeherder is a reporting dashboard for checkins to Mozilla projects (for example, mozilla-central). It allows users to see the results of automatic builds and their respective tests. Treeherder also provides a rich set of APIs that can be used by other projects interested in this information.

Treeherder is the successor to TBPL.

For tracking performance data, see Treeherder's sister project, Perfherder.

For tracking intermittent test failures, see Intermittent Failures View.


To make UI-only changes, you only need to perform a very simple setup running a local webserver pointing at the production backend, described here. If you wish to hack on the backend, or the UI and backend together, you will instead need to set up a Vagrant environment, using these steps.
