CI/CD

You bring your own compute and Buildkite handles orchestration and the UI. Good once you need self-hosted runners without giving up a managed pipeline experience.

A mature, dedicated CI platform that's still actively developed. A reasonable option if GitHub Actions' limits start to bite.

Drop-in replacement for docker build that runs on beefier remote machines with persistent cache, so Docker image builds in CI go from minutes to seconds.

The obvious choice if your code's already on GitHub. Workflows live right next to the repo and the marketplace has an action for almost anything.

The strongest pick if you want repo, CI/CD, and security scanning in one platform instead of stitching tools together.
