4 open-source alternatives

4 Best Open Source Jenkins Alternatives in 2026

Looking for an open source Jenkins alternative? We compared 4 CI/CD platforms by license, self-hosting, pipeline model, and open-core editions. Jenkins is itself open source, so these alternatives mainly offer less maintenance and a more modern pipeline experience, and three of them keep some features in commercial editions.

How we chose these Jenkins alternatives

We looked for tools that overlap with Jenkins' core: running CI/CD pipelines defined as code on your own infrastructure. We verified each project's license, recent activity, stars, and self-hosting in its repository. Jenkins is already open source, so people usually switch for lower maintenance, a simpler pipeline model, or built-in source hosting, and we flag open-core editions. See our methodology for the full criteria.

Important: pipelines must be rewritten

None of these runs Jenkinsfiles unchanged, so moving means rewriting pipelines in the format each tool uses. Woodpecker CI uses container-based workflows, and GitLab uses its own CI/CD configuration. Plan time for migration and testing, especially for plugins your pipelines depend on.

Closest to Jenkins

Woodpecker CI and Semaphore are the closest as dedicated CI/CD systems that you can self-host, with Woodpecker running steps in containers and Semaphore offering a visual workflow builder. Harness and GitLab are full platforms that also host your Git repositories.

Important: open core and commercial editions

GitLab's Community Edition is open source, but many advanced features are in its commercial Enterprise edition. Semaphore's Community Edition is Apache-2.0, while its ee directory is commercial. Harness and Woodpecker CI are Apache-2.0 without a commercial split in their repositories, though Harness also sells commercial products.

License details

Harness and Woodpecker CI are Apache-2.0. Semaphore's Community Edition is Apache-2.0, and GitLab's Community Edition is open source alongside commercial Enterprise functionality.

Maintenance status

Harness, GitLab, Woodpecker CI, and Semaphore all had commits within days of this update.

Why look for a Jenkins alternative?

Jenkins is open source but demanding to run: it relies on a large plugin ecosystem that needs constant updates and security patching, controllers that require careful maintenance, and Groovy-based pipelines that many teams find heavy. The alternatives offer container-native pipelines, simpler configuration, and in some cases an integrated platform, at the cost of a smaller plugin ecosystem than Jenkins.

Harness

Open-source developer platform for source, CI/CD, and environments

Apache-2.0 developer platform evolved from Gitness, combining source-code management, pull requests, code review, CI/CD pipelines, artifact registries, APIs, webhooks, and hosted development environments called Gitspaces.

38.5K3.4KApache-2.0Self-hosted

Pricing: Open-source self-hostable platform; commercial Harness products are also available.

  • Apache-2.0 source and repository hosting
  • Pull requests, reviews, pipelines, and artifact registry
  • Gitspaces and broader developer workflows
  • Heavier than Gitea or Gogs
  • More infrastructure and administration
  • Broader DevOps scope can be excessive for teams needing only Git hosting

Semaphore

Open-source CI/CD platform with an enterprise edition.

Semaphore is a CI/CD and delivery platform whose Community Edition is open source under Apache-2.0 and can be run on your own infrastructure, with features such as test reports, monorepo support, and a visual workflow builder. An Enterprise Edition in the ee directory is under a commercial license, and a hosted version is available at semaphoreci.com. The older semaphoreci/semaphore repository is archived in favor of semaphoreio/semaphore.

1.6K95Apache-2.0 (Community) + commercial Enterprise (ee)Self-hosted

Pricing: Community Edition is free to self-host; the hosted service and Enterprise Edition are paid.

  • Full CI/CD platform with a visual workflow builder
  • Apache-2.0 Community Edition
  • Hosted option if you do not want to manage it
  • The ee directory needs a commercial license
  • Smaller community than Woodpecker or GitLab
