GitHub Actions vs Buildkite

SEPT 2026 audit

A comparison of GitHub Actions and Buildkite built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 23 criteria comparedSources last checked

The short answer

Choose GitHub Actions if…

Repos already on GitHub — no separate CI product to wire up, and self-hosted runners cost nothing to use beyond the hardware itself.

Editorial · Palash Bagchi · approved

Choose Buildkite if…

Teams that already run their own compute and want a CI product built around that from the start, rather than one that treats self-hosting as an escape hatch from a hosted-minutes model.

Editorial · Palash Bagchi · approved

Consider something else if…

  • GitHub Actions: Heavy macOS usage — at $0.062/minute it's by far the most expensive runner type here, and a dedicated CI product may price Mac builds differently.
  • Buildkite: There's no existing infrastructure to run agents on — the per-user Pro price is separate from and additional to whatever compute the agents themselves need.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

Price per extra concurrent jobBuildkite: Additional self-hosted agents beyond the 10 included on Pro: $3.50/agent/month. Hosted Linux agents: $0.004/vCPU-minute; hosted Mac agents: $0.02/vCPU-minute.

Questions this comparison answers.

Entry paid plan: GitHub Actions or Buildkite?

GitHub Actions: GitHub Team: $4 USD per user/month (Free $0, Enterprise $21 USD per user/month).

Buildkite: Pro plan: $30 per active user/month.

Should I choose GitHub Actions or Buildkite?

Pick GitHub Actions if Repos already on GitHub — no separate CI product to wire up, and self-hosted runners cost nothing to use beyond the hardware itself.

Pick Buildkite if Teams that already run their own compute and want a CI product built around that from the start, rather than one that treats self-hosting as an escape hatch from a hosted-minutes model.
