Concourse CI

First Added:May 27, 2026

Concourse CI is an open source CI system built around pipelines as code, immutable container builds, and the “resources / jobs / tasks” model. We assess it for teams that want self-hosted, pipeline-as-data workflows; most new work stays on GitHub Actions or Tekton on Kubernetes.

Blurb

Concourse is an open-source continuous integration and delivery tool with a pipeline-based architecture.

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.
