GitHub Actions vs TeamCity: Managed vs JetBrains CI
TeamCity is JetBrains powerful self-hosted CI with deep build features; GitHub Actions is integrated, low-maintenance CI.
TeamCity is a mature self-hosted (or JetBrains-cloud) CI known for build chains, smart reruns, and great IDE integration. GitHub Actions is integrated CI for GitHub. Here is the comparison.
| GitHub Actions | TeamCity | |
|---|---|---|
| Config | .github/workflows/*.yml | UI + Kotlin DSL |
| Hosting model | GitHub-hosted or self-hosted | Self-hosted server + agents (or cloud) |
| Pricing | Per-minute (hosted) | Free tier + paid agent/server licenses |
| Ecosystem | Actions Marketplace | Plugins + JetBrains integrations |
| Speed levers | Caching, larger/managed runners | Build chains, agent pools, reuse |
| Maintenance | Low (managed) | High (you run server + agents) |
Pricing and maintenance
TeamCity has a generous free tier but you operate the server and build agents, with paid licenses beyond the free agent count. GitHub Actions removes that ops burden for per-minute billing.
Config and ecosystem
TeamCity build chains, snapshot dependencies, and Kotlin DSL are powerful for complex builds and JetBrains shops. Actions wins on GitHub-native integration and marketplace size.
Speed and runners
On GitHub Actions, managed runners (e.g. Latchkey) give self-hosted-style cost (~69% under GitHub-hosted) without running agents, plus warm pools and self-healing that TeamCity agents do not provide out of the box.
The verdict
Keep TeamCity for advanced build chains in a JetBrains-centric org with ops capacity; choose GitHub Actions for low-maintenance integrated CI - with managed runners for cheap, reliable compute.
