Buildkite

Buildkite is a hybrid CI/CD platform where pipeline orchestration runs in the cloud while build agents run on the team's own infrastructure, giving full control over the build environment. Its Test Engine provides AI-assisted flaky test detection and automatic test splitting for parallel execution across agents using historical timing data. An LLM proxy feature allows CI pipelines to call Anthropic Claude models through Buildkite's managed authentication, simplifying AI-powered build steps.
