GitHub Actions vs CircleCI — the tradeoffs that decide it
- Native to your git host: GitHub Actions — Native to GitHub — zero integration, runs where your code is (documented). CircleCI — An extra integration outside GitHub.
When to pick CircleCI instead: when the lines above where it leads matter more to you than the ones where GitHub Actions leads. Change the inputs to see the ranking flip.
This is a capability-fit decision, not a price ranking — these tools bill in incompatible units (per-search vs per-RAM cluster vs per-PB scanned) and several publish rates only in their own calculators, so StackSays does not invent a unified dollar comparison. Every score above traces to a documented capability; see Data sources below.
