Semaphore

Semaphore is a continuous integration and delivery platform that helps product teams build, test and ship software. Pipelines are defined in YAML, can run jobs in parallel, and work with containers, Kubernetes and multi-cloud environments. The project presents it as a delivery platform for AI-driven development as well as traditional workflows.

The code base is written mainly in Elixir and Go, and the repository describes three flavors. The Community Edition is free and open source under Apache 2.0 and meant for teams running Semaphore on their own infrastructure with community support. The Enterprise Edition adds features for larger organizations under a commercial licence with professional support. Semaphore Cloud is the hosted option at semaphoreci.com.

Installing the self-hosted version is said to take roughly 10 to 30 minutes, with detailed guides for different methods, and the repository links to documentation, a roadmap, governance information and a project board. It suits engineering teams that want a modern CI/CD system they can run themselves, or prefer a hosted service with the same engine.
