Buildkite vs Depot
Side-by-side trajectory, velocity, and editorial themes.
Buildkite widens its API surface for agent-driven CI debugging and observability
Buildkite's recent releases cluster around one theme: exposing more of the CI runtime through APIs. Richer REST job and agent objects, per-job performance metrics, and MCP server tooling all aim at automated and agent-driven consumers, alongside a security fix and an infrastructure notice.
The platform is being reshaped for programmatic and agentic use — surfacing signal_reason and runner context so automation can tell infrastructure failures from code failures, adding job-level CPU/memory/disk metrics, and splitting jobs from builds for large-matrix querying. The MCP investment (elsewhere in the feed) is the same bet from another angle.
Expect the REST and GraphQL surfaces to keep expanding toward machine consumers, with the MCP server becoming the primary interface for automated build triage.
Depot extends from build acceleration into hosted source control with Depot Code.
Depot is broadening from a CI and build-cache company into a full developer-infrastructure platform. This cycle it launched Depot Code — a diskless git server backed by S3 blob storage — into private beta, moved CI and Sandboxes onto a re-architected Depot Metal compute tier, and kept extending Depot CI with new triggers, snapshot improvements, OIDC auth, and Datadog observability.
The direction is a vertically integrated build-and-source stack: Depot Code stores git packfiles as S3 objects and runs stateless git workers, mirroring the same storage-compute separation behind Depot Metal. Each piece plugs into Depot CI, so the company is assembling an end-to-end alternative to the hub-and-spoke GitHub model rather than just accelerating it. The CI surface is maturing in parallel with reliability and integration features.
Expect Depot Code to move toward wider access and tighter Depot CI integration, and GitHub Actions runners and container builds to migrate onto Depot Metal over the coming months as promised.
