The short answer

Pick GitHub Actions if your code is on GitHub and you want CI/CD with no servers to run, built from reusable marketplace actions. Pick Jenkins if you need a free, self-hosted automation server that can run anywhere, including air-gapped networks, and works with any code host. The core trade-off is convenience against control: Actions is managed and tied to GitHub, Jenkins is yours to run and maintain.

GitHub Actions or Jenkins: our take

GitHub Actions lives inside GitHub repositories. Workflows are YAML files that run on pushes, pull requests, releases, schedules or manual triggers, using GitHub-hosted Linux, Windows and macOS runners or your own self-hosted ones. Because it sits next to the code, secrets, permissions and pull request checks work without extra setup, and thousands of marketplace actions cover common steps like caching dependencies or deploying to a cloud. Jenkins is an MIT-licensed Java application you install yourself on Linux, Windows or macOS. Pipelines are written in a Groovy-based Jenkinsfile, a controller hands jobs to agents on any platform, and its large plugin ecosystem connects it to almost every source host, build tool and cloud.

Cost works differently. Actions is free on public repositories and on self-hosted runners; private repositories get a monthly allowance (2,000 minutes on GitHub's Free plan, 3,000 on Team) and then pay per minute, with Linux minutes at $0.006. Jenkins itself is free, but you pay in servers and staff time: upgrades, plugin compatibility, security patches and scaling are your job, and the interface feels dated next to hosted services.

The limits differ too. Actions only works with code hosted on GitHub, its hosted runners are slower than specialist providers, and large YAML workflows get hard to debug. Jenkins can become hard to manage as Groovy pipelines and plugin lists grow, but nothing about it is tied to one vendor, and it runs inside networks that cannot reach the internet.

For teams already on GitHub, especially smaller ones or open-source projects, Actions is the easier default. Jenkins makes more sense for organisations with existing Jenkins expertise, code spread across several hosts, strict on-premises requirements, or unusual build environments that need a plugin only Jenkins has.

Choose GitHub Actions if…

Teams hosting code on GitHub who want CI/CD right next to their repositories
You need Web, which Jenkins doesn't list
No separate tool to set up for GitHub repos
Large marketplace of reusable actions

Choose Jenkins if…

Teams that need fully self-hosted, highly customisable CI and can maintain it
You want open-source software
You need to host it on your own servers
You need Linux, Windows and macOS, which GitHub Actions doesn't list
Free and runs anywhere, including air-gapped networks

What is GitHub Actions?

GitHub Actions is the CI/CD and automation service built into GitHub repositories. Workflows are YAML files in the repo that run on events such as pushes, pull requests, releases, schedules or manual triggers, executing jobs on GitHub-hosted Linux, Windows and macOS runners or on your own self-hosted runners. Thousands of reusable actions in the Marketplace handle common steps like setting up languages, caching dependencies, publishing packages and deploying to clouds, which makes simple pipelines quick to assemble. Because it lives next to the code, permissions, secrets and pull request checks are integrated without extra setup. The limits show on large or complex pipelines: debugging YAML, slow hosted runners and per-minute costs on private repos lead many teams to faster third-party runners or dedicated CI services. Usage is free on public repositories with standard runners and on self-hosted runners; private repositories get a monthly minute allowance by plan, then per-minute billing.

What is Jenkins?

Jenkins is the open-source automation server that much of the industry's CI started on, and it still runs in countless companies. It is a self-contained Java application you install on your own servers, with packages for Windows, Linux and macOS and official Docker images. Pipelines are written as code in a Jenkinsfile using a Groovy-based syntax, and controllers distribute work to agents on any platform. The plugin ecosystem, with well over a thousand plugins, means Jenkins can integrate with almost every SCM, build tool, cloud and notification service. That flexibility is also its burden: you are responsible for upgrades, plugin compatibility, security patches and scaling, and the interface feels old next to modern hosted services. It is free under the MIT licence and governed by the Continuous Delivery Foundation, with commercial support available from vendors such as CloudBees. It runs on Linux, Windows and macOS.
