Buildkite review

Buildkite is built for teams whose CI load has outgrown shared hosted runners. Pipelines run on agents you connect, with no limit on parallel builds, or on Buildkite hosted agents billed per vCPU minute at $0.004 on Linux and $0.02 on Mac, metered to the second. Dynamic pipelines can generate their own steps at runtime, which helps large monorepos build only what changed. The Free plan covers up to 5 active users, up to 10 concurrent jobs and up to 2,000 Linux vCPU minutes. Pro costs $30 per active user per month, supports up to 50 users, includes 10 self-hosted agents and charges $3.50 per extra agent, and includes 1 million test executions a month for flaky test detection. The weaknesses are price and effort: it is the most expensive seat here, and running your own agent fleet takes engineering time. For smaller teams the free plan or a built-in CI is usually enough.

Who it is for

Platform teams running very large or highly parallel workloads, including big monorepos.

Price

Free plan for up to 5 users; Pro $30 per active user per month.
