CircleCI vs Buildkite

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

Updated 5 criteria comparedSources last checked

The short answer

Pick CircleCI if
Teams running mostly on self-hosted runners, where build-minute cost disappears entirely and the credits system only meters users and premium features.
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.

3 sourced criteria separate them:

Entry paid plan
CircleCI: Performance plan: starting at $15/month, including 30,000 free credits plus additional paid credits.
Buildkite: Pro plan: $30 per active user/month.
Pricing model
CircleCI: Credits-based: purchased up-front and consumed in real time for compute usage, active users and premium features. Network egress beyond the plan allowance is billed at 420 credits per GB.
Buildkite: Hybrid: per-user subscription plus consumption-based pricing for hosted agents, billed per vCPU-minute metered to the second, with no minimums and no rounding.
Self-hosted runners
CircleCI: Supported on every tier: 5 concurrent self-hosted tasks on Free, 20 on Performance, unlimited on Scale. No per-minute charge for self-hosted runner builds.
Buildkite: Self-hosted agents are the default model, not an add-on. Free plan includes up to 10 concurrent jobs; Pro plan includes 10 self-hosted agents.

Only criteria both providers publish appear here; a tinted cell marks a real difference. Criteria only one of them documents are listed below, and an absence there means we found no source — not that the feature is missing. How we source this.

The small bar above a value is inetGeek's own lean toward that side — computed from the same facts shown, never a number the provider published. See the picker below "The short answer" to weigh only the criteria you care about.

Consider something else if…

  • CircleCI: The workload is small and simple — a credits system adds a layer of currency conversion a flat per-minute or per-user price doesn't.
  • 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.
