The original CI/CD automation server
Jenkins automates builds, tests, and deployments with 1,800+ plugins covering virtually every tool in the software development ecosystem. Jenkins is the original and still the most extensible.
Simple yet powerful CI/CD engine
Woodpecker is a self-hosted CI engine that's dead simple to set up. It's a community fork of Drone CI, after Drone went commercial.
CircleCI is a platform — it bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
Including when one of these alternatives ships a major update. Free.
