Jenkins vs Woodpecker vs Drone – Open Source CI/CD Compared

Continuous integration and delivery is the backbone of modern software work, and the tooling you pick shapes how quickly your team ships. Three names dominate the self-hosted conversation: Jenkins, the long-standing automation workhorse; Woodpecker CI, a lean community fork; and Drone CI, once the darling of container-native pipelines. They look similar on the surface, but their licensing, architecture and maintenance models differ sharply — and one of them is no longer open source at all. Here is how they compare.

Jenkins

Jenkins is the oldest and most widely deployed open source automation server. Written in Java and released under the permissive MIT licence, it runs anywhere a JVM runs and is extended by a plugin ecosystem of well over a thousand integrations. If a tool, cloud or language exists, there is probably a Jenkins plugin for it.

Strengths

• Enormous plugin ecosystem: source control, build tools, cloud providers, notifications and deployment targets are all covered by community plugins.
• Pipeline as code: declarative and scripted Jenkinsfiles let you version build logic alongside your source.
• Truly self-hosted and free: an MIT-licensed core with no per-user fees, seat limits or revenue caps.
• Mature LTS line: a stable long-term-support baseline is chosen every 12 weeks, with security backports in between. The current LTS is 2.580.1 (September 2026), while the weekly line tracks newer features on 2.584.
• Huge community: decades of documentation, books, conference talks and enterprise case studies.

The trade-offs are equally well documented: Jenkins is resource-hungry, its UI feels dated, plugin quality varies, and a large plugin dependency graph becomes a maintenance job in itself. For teams that need maximum flexibility and a proven track record, though, it remains the safe default.

Woodpecker CI

Woodpecker CI is a lightweight, Apache-2.0-licensed CI engine written in Go. It was forked in 2019 from Drone 0.8 — the last release before Drone changed licence — and has since grown into a fully independent project that works with GitHub, GitLab, Gitea, Forgejo and Bitbucket.

Strengths

• Genuinely open source: Apache 2.0 throughout, with an explicit community commitment to stay free and open source.
• Lightweight and fast: a small Go server plus Docker-native agents, so it runs comfortably on modest hardware.
• Simple YAML pipelines: a clean, readable configuration model inherited from Drone — quick to learn and easy to review in a pull request.
• Broad forge support: GitHub, GitLab, Gitea, Forgejo and Bitbucket out of the box, with Docker, Kubernetes and local backends for running steps.
• Active development: version 3.18.0 landed in August 2026, adding pipeline log downloads, tighter plugin environment handling and Kubernetes improvements.

Woodpecker is the pragmatic middle ground: closer to Drone’s elegant, container-first design than to Jenkins’ sprawling plugin model, but under a licence you can actually build a business on. It does not match Jenkins’ plugin breadth and its ecosystem is smaller — yet for container-first teams it is often the sweet spot.

Drone CI

Drone CI popularised container-native, YAML-driven pipelines and was originally released under the Apache 2.0 licence. That changed after Harness acquired Drone.io in 2020 and the licence moved away from Apache 2.0. Today Drone is not open source: the current code, now rebranded Harness Open Source (still in beta as of 2026), is published under the Polyform Small Business License — a source-available licence that restricts commercial use for organisations above a revenue threshold. A genuinely Apache-2.0 “Open Source Edition” still exists in principle, but there is no official distribution: you have to compile it yourself with special build tags.

Strengths

• Clean, container-native design: every pipeline step runs in a Docker container, and plugins are containers too.
• Pipeline as code: a concise .drone.yml file describes the whole build, test and deploy flow.
• Git-native: tight integration with GitHub, GitLab, Bitbucket and Gitea, triggered by webhooks.
• Stable 2.x for existing users: Drone 2.x remains supported on the drone branch while Harness Open Source matures.

The catch is the licensing. Because Polyform Small Business is source-available rather than open source, Drone no longer qualifies as free software for most businesses — and its development has been folded into Harness Open Source. If you were drawn to Drone for its open licence, Woodpecker, its direct descendant, is where that community went.

Side-by-side comparison

Which should you choose?

Start with Jenkins if you need the widest possible integration surface, a battle-tested LTS, or you are maintaining an existing Jenkins estate. It is the most flexible option, at the cost of heavier infrastructure and more upkeep.

Choose Woodpecker CI if you want Drone’s clean, container-first pipeline model under a truly open licence. It is the lightest of the three to run and the easiest to reason about — ideal for small teams, homelabs and self-hosted Git forges such as Gitea and Forgejo.

Consider Drone CI only if you already run it, or if Harness Open Source’s bundled code-hosting features appeal to you — and you are comfortable with a source-available licence and a revenue-capped free tier. For everyone else starting fresh and wanting open source, Woodpecker carries Drone’s torch further.

All three run on your own hardware and keep your build history on your own servers. You can browse hundreds more free and open source tools in the directory, learn more from the projects themselves at jenkins.io, woodpecker-ci.org and drone.io, or suggest a tool we are missing.
