Buildkite vs Depot
Side-by-side comparison of features, pricing, ratings, and alternatives.
Buildkite is a CI/CD platform for building, testing, and deploying software, distinguished by a hybrid architecture where the control plane is hosted but build agents run on infrastructure you control, whether that's your own servers, Mac hardware, GPUs, or Kubernetes. Pipelines support dynamic steps, conditional logic, and wait/block steps for approval gates. Beyond core pipelines, Buildkite offers a Test Engine for flaky test detection and analytics, package registries for supply-chain security, and a Mobile Delivery Cloud tuned for iOS and Android release workflows. It's used by large-scale engineering teams; Buildkite cites Uber running 100,000 concurrent agents and cutting monorepo build times in half.
Depot is a build acceleration platform that replaces slow, uncached Docker builds and generic CI runners with infrastructure purpose-built for speed. It plugs into existing GitHub Actions workflows and Docker tooling, automatically caching build layers across every run so teams stop rebuilding the same code from scratch. Beyond container builds, Depot offers faster GitHub Actions runners and a programmable CI engine (Depot CI) that speaks the GitHub Actions syntax teams already know, plus remote caching for tools like Bazel, Go, Gradle, and Turborepo. Billing is per-second, so teams pay only for the compute they actually use instead of renting idle runners.
- Hybrid model keeps source code and secrets on your own infrastructure
- Scales to very high concurrency for large monorepos
- Test Engine adds flaky-test detection beyond basic CI
- Flexible agent types including Mac, GPU, and Kubernetes
- Meaningful build-time reduction from automatic layer caching
- Drop-in replacement for GitHub Actions runners with minimal workflow changes
- Per-second billing avoids paying for idle runner time
- Support for non-Docker build caches like Bazel and Turborepo
- Requires managing and maintaining your own build agents
- Pro tier pricing is per active user, which can add up for larger teams
- Enterprise features require a custom sales conversation
- Primarily useful for teams already invested in Docker and GitHub Actions
- Business-tier pricing and infrastructure options are not publicly listed
- No permanent free plan, only a time-limited trial
