GitHub Actions vs GitLab CI vs Jenkins: How to Choose

Picking a CI/CD tool feels like a big, permanent decision. It isn’t quite permanent, but switching later does cost weeks of rewriting pipeline files and retraining people. So it pays to choose for the right reasons.

Most comparisons rank GitHub Actions, GitLab CI/CD and Jenkins by feature lists. That misses the point. All 3 can build, test and deploy almost anything. The real differences are where your pipelines run, who maintains the system, and how well it fits the tools you already use. This guide compares them on exactly those 3 things.

If you are new to the concept itself, start with our explainer on what CI/CD is, then come back here.

The short version

• GitHub Actions is built into GitHub. If your code is already there, it is the path of least resistance. GitHub runs the build machines for you, or you can bring your own.
• GitLab CI/CD is built into GitLab. It suits teams that want one platform for code, pipelines, issue tracking and security scanning, and it can be fully self-managed on your own servers.
• Jenkins is an open source automation server you install and run yourself. It works with any Git host and almost any tool, but your team owns every upgrade, plugin and server.

Key takeaway: For most teams, the best CI/CD tool is the one that lives next to your code. Choose Jenkins only when you have a specific need for its control and flexibility, and the people to run it.

Side-by-side comparison

Hosting: who runs the machines

Every CI/CD system has 2 parts: a control plane that schedules jobs and stores results, and the runners (or agents) that actually execute your builds. Where each part lives drives your cost, your security posture and your maintenance load.

GitHub Actions

GitHub runs the control plane. For runners, you have 2 choices. GitHub-hosted runners are fresh virtual machines running Ubuntu Linux, Windows or macOS that GitHub spins up for each job. Self-hosted runners are machines you register yourself, useful when you need special hardware, access to a private network, or more control over cost.

GitHub’s billing documentation says Actions usage is free for public repositories on standard GitHub-hosted runners and for self-hosted runners. Private repositories get a monthly allowance of included minutes that depends on the plan, for example 2,000 minutes on GitHub Free and 3,000 on GitHub Team, with paid usage beyond that.

Pricing has been moving. GitHub cut hosted runner prices by up to 39% from January 1, 2026. It also announced a per-minute platform charge for self-hosted runners, then said in December 2025 that it was postponing that change to re-evaluate it. Check GitHub’s current billing docs before you budget.

GitLab CI/CD

GitLab gives you more hosting choices than either rival. On GitLab.com, GitLab runs the platform and offers hosted runners, with compute minutes included in each tier. Its pricing page lists 400 minutes per month on Free, 10,000 on Premium and 50,000 on Ultimate. You can also register your own runners using the open source GitLab Runner.

Or you can run the entire GitLab platform yourself as GitLab Self-Managed. That appeals to regulated industries and companies with strict data residency rules, because code, pipelines and logs never leave your infrastructure.

Jenkins

Jenkins is self-hosted by design. The project describes it as a self-contained Java-based program that runs on Windows, Linux, macOS and other Unix-like systems. You run a controller and connect agents to it, either fixed servers or agents created on demand in Kubernetes or a cloud account.

The software is free, but the servers, storage, backups and the engineering time to keep it all healthy are not.

Maintenance: the cost nobody puts on the slide

Maintenance is where these tools differ most, and where teams most often underestimate the work.

GitHub Actions and GitLab.com are managed services. The vendor patches the platform, scales the scheduler and keeps hosted runners up to date. Your team maintains pipeline files and any self-hosted runners you choose to add.

GitLab Self-Managed shifts the platform work to you. You plan upgrades, run backups and size the servers. GitLab publishes detailed upgrade paths, but someone has to own them.

Jenkins puts everything on your team: the controller, the agents, Java versions, plugin updates and security advisories. The plugin ecosystem is Jenkins’s biggest strength and its biggest chore. Plugins depend on each other, and an upgrade to one can break another. Teams that run Jenkins well usually treat it as a product with a named owner, configuration stored as code, and a test environment for upgrades.

If your team has no dedicated platform or DevOps engineer, that table usually settles the question. Our guide to platform engineering explains how larger companies staff this work.

Ecosystem fit: where your code and tools already live

If your code is on GitHub

GitHub Actions wins on convenience. Pull request checks, required status checks, secrets, environments and deployment approvals all live in the same place as your code. The Marketplace offers a large library of reusable actions for common steps like setting up a language, caching dependencies or deploying to a cloud.

One caution: a third-party action is code that runs inside your pipeline with access to your secrets. Pin actions to a specific commit or trusted version, and review what you pull in. Our explainer on supply chain attacks covers why this matters.

If your code is on GitLab

GitLab CI/CD is the natural choice. Merge request pipelines, environments, container registry and security scanning features are built into the same product, with more of the advanced features in the paid tiers. GitLab can also run pipelines for code hosted elsewhere, including GitHub, through its CI/CD for external repositories feature on Premium and Ultimate.

If your tools are a mix

Jenkins shines in mixed or older environments. It works with GitHub, GitLab, Bitbucket and self-hosted Git servers, and has plugins for build tools, test frameworks and deployment targets that newer platforms may not cover. If you build software for embedded hardware, run builds on unusual operating systems, or must stay completely inside an air-gapped network, Jenkins is often the practical answer.

When each tool is the right call

There is no shame in staying on Jenkins if it works and someone owns it. There is real cost in staying on a Jenkins server nobody understands.

How to choose in 5 steps

1. Start from your Git host. If you are on GitHub or GitLab and have no blocking requirement, use the built-in CI/CD. You save integration work immediately.
2. List hard constraints. Data must stay on-premises? Special hardware? Air-gapped network? Write these down first, because they can eliminate options quickly.
3. Estimate the maintenance load honestly. Who will patch, upgrade and back up the system? If the answer is “nobody in particular,” choose a managed service.
4. Price it with real numbers. Count your monthly build minutes, check whether you need macOS or larger runners, and compare against each vendor’s current pricing page. Add server and staff time for self-hosted options.
5. Run a small pilot. Move one real service’s pipeline, including tests and a staging deploy, and measure build time and how easy it was to debug failures. Our step-by-step guide to building a CI/CD pipeline includes sample GitHub Actions and GitLab configs you can use.

Once the pipeline runs, track delivery performance with DORA metrics so you can tell whether the new setup actually helps.

Migrating between tools

Migrations are usually smoother than teams fear, because pipelines are mostly shell commands wrapped in YAML or Groovy. GitHub and GitLab both publish migration guides from Jenkins, and GitHub offers an importer tool that converts some Jenkins pipelines automatically.

Migrate one service at a time, run old and new pipelines in parallel for a short period, and retire the old jobs once the new ones are trusted. Move secrets carefully, and rotate them after the move.

Conclusion

GitHub Actions, GitLab CI/CD and Jenkins are all capable. The right one depends on where your code lives, how much infrastructure your team wants to own, and any hard rules about where builds must run. Default to the CI/CD built into your Git host, and choose Jenkins on purpose, not out of habit.
