Apple’s new Containerization framework (announced at WWDC 2025) is interesting here. Unlike Docker on Mac, which runs all containers inside a single shared Linux VM, Apple gives each container its own lightweight VM via the Virtualization framework on Apple Silicon. Each container gets its own kernel, its own ext4 filesystem, and its own IP address. It is essentially the microVM model applied to local development, with OCI image compatibility. It is still early, but it collapses the gap between “local development containers” and “properly isolated sandboxes” in a way that Docker Desktop never did.
