Good fit for Platform / SRE teams that want declarative pipeline-as-data and reproducible builds with explicit resource versioning.
Weak at Steep learning curve; the resource/task abstraction is unfamiliar to teams coming from CircleCI's job/step model.

Replaces these SaaS
- CircleCI · Hosted CI/CD
Pull `concourse/concourse:7` with the `quickstart` compose from concourse-ci.org. Concourse is opinionated: pipelines, jobs, resources (everything is a resource — git repo, Docker image, S3 bucket), and tasks. Migrating a CircleCI config is a redesign rather than a port — write the equivalent pipeline in Concourse YAML. Higher learning curve, but the pipeline-as-data model scales well at large orgs.
