Semaphore

Semaphore is a CI/CD platform for building, testing, and deploying software, available as a managed cloud service, an on-premise enterprise edition, and an open-source community edition. Its open-source sem-ai CLI lets AI coding assistants debug pipelines, analyze failing tests, and perform critical-path and blast-radius analysis through an embedded MCP server. It also detects a repository's tech stack to propose pipeline configuration from natural language.
