CI/CD pipelines that run on your own infrastructure at any scale.

What is Buildkite?

Buildkite is a CI/CD platform for building, testing, and deploying software, distinguished by a hybrid architecture where the control plane is hosted but build agents run on infrastructure you control, whether that's your own servers, Mac hardware, GPUs, or Kubernetes. Pipelines support dynamic steps, conditional logic, and wait/block steps for approval gates. Beyond core pipelines, Buildkite offers a Test Engine for flaky test detection and analytics, package registries for supply-chain security, and a Mobile Delivery Cloud tuned for iOS and Android release workflows. It's used by large-scale engineering teams; Buildkite cites Uber running 100,000 concurrent agents and cutting monorepo build times in half.
