Concourse CI

Concourse is an open source continuous automation system that is strong at CI and CD. Pipelines are built from resources, tasks and jobs, and they are defined as code.

A Concourse pipeline describes the inputs each job needs, such as a git repository, and the actions to run when those inputs change. The web interface draws the pipeline as a graph, so you can move from a failed job to the cause in a few clicks. You set pipelines with the fly command line tool, and you can keep the pipeline file in source control.

• Pipelines defined in YAML and kept in git
• Web view of jobs and resources as a graph
• Command line tool for setting pipelines
• Intercept a running build for debugging
• Jobs can depend on other jobs

DevOps teams and platform engineers who want a CI system where configuration is code and every build runs in a clean environment. It suits projects that need several dependent jobs and resources in one pipeline.

Concourse is open source under the Apache-2.0 licence and is free to use. You run the server yourself, so you are responsible for hosting, upgrades and access control. The project lists sponsors and a support option on its site if you want help with operations.
