Buildkite (buildkite)

Buildkite is a CI/CD platform that pairs a hosted control plane with self-hosted (or hosted) agents. The platform exposes a REST API, GraphQL API and Agent API. Resource families include organizations, pipelines, pipeline templates, builds, jobs, agents, clusters, queues, teams, rules, artifacts, annotations and access tokens. Test Engine adds test-execution endpoints.
