Concourse CI

Concourse CI. Is an open source CI system built around pipelines as code, immutable container builds, and the “resources / jobs / tasks” model.
Summary
Model: fly CLI sets pipelines from YAML; workers run steps in containers; resources poll git, S3, and other endpoints for new versions.
When to use: air-gapped or self-hosted CI with strong isolation; teams already running Concourse at scale with dedicated platform engineers.
When to skip: managed SaaS preference; need rich marketplace actions (Actions wins); small teams without ops capacity to run the Concourse cluster.
