What is Buildkite?
Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.
Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.
What is Depot?
Depot is closing the last gaps between its CI and the GitHub Actions it wants to replace
Depot CI keeps absorbing the things a team would otherwise stay on GitHub-hosted runners for: Arm64 sandboxes up to 64 CPUs, native stacked pull request handling, macOS 26 on M4 hardware, rebuilt Windows Server images carrying Visual Studio 2026, and a us-east-1 Ubuntu package mirror. Behavior details are being tuned too — pull request runs no longer cancel on a new commit unless a concurrency group says so. The newest release moves Datadog CI Visibility out of private beta, exporting every run as a pipeline with jobs, steps, and retries intact.

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.
◆ Current state
Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.
◆ Where it's heading
The pattern is to centralize and codify: settings move from individual agents to clusters, and from the UI to Terraform and APIs, and capabilities such as caching move from plugins into the agent itself. Test Engine is turning into a programmable flaky-test management layer instead of a dashboard.
◆ Prediction
Expect more Test Engine monitors and actions that can be managed in code, and cache controls such as eviction and scoping, now that Cache is GA.

Depot is closing the last gaps between its CI and the GitHub Actions it wants to replace
◆ Current state
Depot CI keeps absorbing the things a team would otherwise stay on GitHub-hosted runners for: Arm64 sandboxes up to 64 CPUs, native stacked pull request handling, macOS 26 on M4 hardware, rebuilt Windows Server images carrying Visual Studio 2026, and a us-east-1 Ubuntu package mirror. Behavior details are being tuned too — pull request runs no longer cancel on a new commit unless a concurrency group says so. The newest release moves Datadog CI Visibility out of private beta, exporting every run as a pipeline with jobs, steps, and retries intact.
◆ Where it's heading
The strategy is substitution rather than differentiation: match the incumbent's compatibility surface, beat it on hardware and cache, then let existing tooling see Depot as just another pipeline. Datadog export is the clearest expression of that — it makes Depot legible to the monitoring a team already runs instead of asking them to adopt a new dashboard. The CLI work on project get, update, and cache retention points the same way, toward scripts and agents managing Depot without the UI.
◆ Prediction
Expect the us-east-1 package mirror to expand to other regions, and the observability work to extend past Datadog to other OpenTelemetry-compatible destinations.
