Four budget-friendly CI/CD tools for Java developers — from free open-source options to low-cost managed plans — all under $100/month. Includes Argo CD, Tekton, Travis CI, and GitLab Self-Managed.
If you're a Java developer looking to set up continuous integration and delivery without blowing your budget, you're in luck. The CI/CD landscape has matured to the point where excellent options exist at every price point — including completely free. The key trade-off is managed ease versus self-hosted savings.
Here are four tools that handle Java build cycles (Maven, Gradle, the works) while staying under $100/month.
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes, maintained by the CNCF. It's completely free and open-source.1 If your Java applications already run on Kubernetes, Argo CD gives you a robust way to sync your deployments directly from your Git repository.
Best for: Teams already on Kubernetes who want a free, battle-tested GitOps solution.
Cost: $0 (open-source, self-hosted).
Tekton is a powerful and flexible open-source framework for building CI/CD systems, also under the CNCF umbrella.4 It runs natively on Kubernetes and lets you define pipelines as custom resources. Java builds with Maven or Gradle fit naturally into Tekton's task-based model.
Best for: Teams that want full control over their pipeline definition and are comfortable with Kubernetes.
Cost: $0 (open-source, self-hosted).
Travis CI offers usage-based pricing starting at $15 per month for small teams.2 It's a fully managed service, so you don't need to maintain infrastructure. Travis CI has long been a favorite in the open-source community and supports Java builds out of the box.
Best for: Small teams that want a managed CI service with a low entry cost and minimal ops overhead.
Cost: Starts at $15/month.
GitLab's Free tier is solid for individual developers or small teams working on personal projects.3 The self-managed version gives you a complete DevOps platform — CI/CD, container registry, and more — all on your own infrastructure. Java pipelines with Maven or Gradle are straightforward to configure.
Best for: Developers who want an all-in-one platform with a generous free tier and the ability to self-host.
Cost: Free tier available; paid tiers start at $19/user/month.
| Dimension | Argo CD | Tekton | Travis CI | GitLab Self-Managed |
|---|---|---|---|---|
| Cost | Free | Free | From $15/mo | Free tier |
| Hosting | Self-hosted (K8s) | Self-hosted (K8s) | Managed | Self-hosted |
| Java support | GitOps + K8s | Custom pipelines | Native | Native |
If you're already on Kubernetes, Argo CD or Tekton give you enterprise-grade CI/CD for free — you just pay for the infrastructure. If you'd rather not manage servers, Travis CI gets you started at $15/month. And if you want a full DevOps platform with a generous free self-hosted tier, GitLab Self-Managed is hard to beat.
All four stay comfortably under $100/month. Pick the one that matches your infrastructure and ops appetite.
