Semaphore

Meet Semaphore

Semaphore runs continuous integration workflows that build and test software changes. Developers define the steps and environment a project needs, then inspect pipeline results before merging or releasing code. The platform also provides a test environment where coding agents can run CI work before pushing changes to the repository.

Agent tools can help configure a pipeline, investigate a failed build, or identify slow and unreliable tests. Reusable environments let subsequent runs retain a prepared workspace instead of repeating every setup step. Teams can manage access to secrets and use administrative controls around their workflows, with open-source and enterprise deployment options available for different operating needs.
