Buildkite is an Australian continuous integration and continuous delivery (CI/CD) software platform headquartered in Melbourne. Founded in 2013, the company provides a hybrid developer platform that separates orchestration from execution, allowing enterprise engineering teams to run high-concurrency build, test, and deployment jobs on their own secure infrastructure (AWS, GCP, Kubernetes, or on-premises) while managing pipeline coordination via Buildkite's cloud control plane.
