Build Docker Images 40x FASTER with This Tool (depot.dev)

Depot.dev is a cloud-based Docker build service that can dramatically reduce container build times from minutes to seconds. The service works by offloading builds to faster cloud machines and implementing sophisticated caching that persists across builds and team members. The tutorial demonstrates setting up Depot with a multi-service project using Docker Compose, showing how teams can share build cache to benefit from each other's builds. While it's a premium service, it offers significant time savings for development teams working with frequent Docker builds.
