Who it's for

Software teams that need CI/CD pipelines to build, test, and deploy their code, from small projects to enterprises with monorepos, containers, mobile apps, or compliance requirements.

What you get

Pipelines defined as YAML, organized into blocks and jobs, with parallel execution and dependency graphs (DAGs). You get fast, production-like sandbox environments, built-in test reporting and flaky-test detection, caching and Docker registry support, and promotions to gate or automate deployments across environments. Available as a hosted cloud service or self-hosted using your own infrastructure.

How it works

You define a pipeline configuration file describing the sequence of blocks and jobs to run on each push or pull request; Semaphore's job runners (cloud-hosted or self-hosted agents) execute those jobs in parallel, and promotions chain additional pipelines together for staged delivery to production.
