Buildkite provides a highly scalable orchestration layer for running CI/CD workflows, optimizing tests, and managing artifact registries across mixed compute environments. It supports both hosted and self‑hosted agents, including Kubernetes, cloud VMs, and macOS build hosts.

Key capabilities include dynamic pipelines that adapt at runtime, a test engine for quarantining and splitting flaky tests, fast package registries with policy controls, and a mobile delivery environment for end-to-end app pipelines. The platform exposes APIs, webhooks and integrations to fit into existing toolchains.

Built for teams operating at scale, it emphasizes security controls, auditability, and enterprise features like SSO, RBAC, and compliance options. Resources include example pipelines, public projects, case studies, webinars and migration services to help teams adopt the system quickly.
