Depot Has a Free API: The Docker Build Service That Makes CI 20x Faster

Docker builds in CI are painfully slow. Every push downloads base images, reinstalls dependencies, and rebuilds layers from scratch. Depot fixes this with persistent caching and native multi-platform builds that make Docker builds up to 20x faster. What Is Depot? Depot is a remote Docker build service. Instead of building images on ephemeral CI runners with no cache, Depot runs builds on persistent, cache-optimized infrastructure. Your Dockerfiles stay the same — builds just get dramatically faster. The Free API Depot offers a solid free tier: Free plan : 100 build minutes per month Persistent cache : Layers persist between builds Multi-platform : Build amd64 and arm64 natively (no QEMU emulation) CLI + API : Programmatic access to all build features GitHub Actions integration : Drop-in replacement for docker/build-push-action Quick Start Install the CLI: curl -L https://depot.dev/install-cli.sh | sh Build your Docker image: # Initialize a project depot init # Build with persistent cac
