Open-source CI/CD tools

2 SaaS tools with self-hostable alternatives

Buildkite alternatives

Buildkite is a CI/CD platform that runs pipeline steps on your own infrastructure (agents you host) while managing the orchestration, dashboard, and queue centrally via Buildkite's SaaS control plane. It is used by engineering teams who need CI at scale on custom or on-prem hardware without managing a full self-hosted CI system. Pipelines are defined in YAML with support for dynamic step generation.

GitHub Actions alternatives

GitHub Actions is GitHub's CI/CD and automation platform where workflows are defined in YAML files triggered by repository events (push, pull request, schedule, etc.). It runs steps on GitHub-hosted runners (Ubuntu, Windows, macOS) or self-hosted runners, with a marketplace of 20,000+ reusable actions. Used for everything from test automation to deployment pipelines to repository maintenance bots.
