Best forTeams of roughly 5-150 engineers running frequent Linux, ARM or container builds who are unhappy with pipeline wall-clock time, want per-minute billing with no seat tax, and are willing to pay for fast human support or to self-host via Community Edition.Engineering organisations of roughly 50+ engineers with a platform or SRE team, running monorepos, Bazel, large test suites or macOS/mobile builds, who need build execution inside their own security boundary — including teams migrating off self-managed Jenkins.
Avoid if Your workflow already lives entirely in GitHub or GitLab, you are macOS/iOS-dominant, you need a contractual response-time SLA on a small budget, you require verified SOC 2 / ISO 27001 evidence up front, or you need flexible refunds and mid-term cancellation. You have fewer than ~10 engineers or no infrastructure owner, want a zero-ops fully hosted runner, need audit logs/SCIM/private log storage on a Pro budget, need ephemeral preview or staging environments, or require a published enterprise price before engaging sales.

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
