Buildbot vs. Semaphore

BuildBot is a system to automate the compile/test cycle required by most software projects to validate code changes. By automatically rebuilding and testing the tree each time something has changed, build problems are pinpointed quickly, before other developers are inconvenienced by the failure.

Whenever somebody pushes new code to GitHub, Semaphore immediately runs all tests on the corresponding branch. Every time you create a new branch, Semaphore builds it automatically. It also knows how to clean up when you delete it.
