The original CI/CD automation server
If you need a CI/CD server and want something that has a plugin for literally everything — 1,800+ plugins covering every build tool, cloud provider, notification service, and deployment target imaginable — Jenkins is the original and still the most extensible. It's been around since 2011 and there isn't a workflow it can't handle.
Simple yet powerful CI/CD engine
If you want a CI/CD system — the thing that automatically tests and deploys your code when you push it — and you don't want to pay for GitHub Actions minutes or depend on a hosted service, 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.
