GitHub Actions vs Jenkins:which should you choose?
Hosted, marketplace-driven workflows next to the world’s largest code host, versus the self-hosted automation server you control completely.
| GitHub Actions | Jenkins | |
|---|---|---|
| Model | YAML workflows in repo; hosted runners or self-hosted; huge marketplace of actions. | Standalone server; Jenkinsfile; plugins. |
| Cost | Free minutes for public/small; paid per minute beyond; self-hosted runners free. | Free software; you pay for servers and the engineer who maintains it. |
| Maintenance | Near zero with hosted runners. | Significant: upgrades, plugins, agents, security. |
| Security | OIDC to clouds, Dependabot, code scanning integrated. | Depends on plugins and hardening. |
| Control / data residency | Hosted by GitHub (self-hosted runners keep builds in your network). | Fully in your control. |
| Best fit | Teams on GitHub; open source; startups. | Regulated/air-gapped environments; complex legacy pipelines. |
Choose GitHub Actions if…
- Your code is on GitHub
- You want zero CI infrastructure to maintain
- You use the actions marketplace and OIDC cloud auth
Choose Jenkins if…
- Builds must stay inside your network entirely
- You need exotic agents or a bespoke build farm
- You already have a well-run Jenkins estate
Our verdict
What we tell clients
GitHub Actions for anyone already on GitHub — it removes an entire class of maintenance. Jenkins only where control or legacy demands it. For air-gapped or regulated environments, self-hosted runners on Actions, or GitLab self-managed, usually beat a fresh Jenkins build.

FAQ
Questions we get on calls
Are GitHub-hosted runners safe for private code?
Yes for most companies; for strict residency use self-hosted runners in your VPC/data center.
Cost at scale?
Hosted minutes add up for large monorepos; self-hosted runners on a Proxmox cluster cut it to near zero.
Can we migrate Jenkinsfiles?
There is no 1:1 converter; most teams rewrite pipelines in YAML service by service — usually simpler afterwards.
