Colima

That's it. Docker, containerd, and Kubernetes, running on your Mac without the Docker Desktop license headache. (one of the fastest in this batch), MIT license, Go. Uses Lima (Linux virtual machines on macOS) under the hood. Supports Docker and containerd runtimes, Kubernetes via k3s, volume mounts, port forwarding, and custom VM resources. Works on both Intel and Apple Silicon.

Fully free. No paid tier, no license restrictions. Docker Desktop requires a paid subscription for companies with 250+ employees or $10M+ revenue. Colima has no such restriction.

Every Mac developer who uses Docker: try this. Solo: `brew install colima && colima start` and you're running containers. Small to large teams: eliminates Docker Desktop licensing entirely. The only question is compatibility.

The catch: it's a VM-based approach, so file system performance on mounted volumes is slower than native. Some Docker Desktop features (the GUI, Extensions, Dev Environments) don't exist. If you rely on Docker Desktop's graphical interface, you'll miss it. And edge cases with networking or volume mounts occasionally require troubleshooting that Docker Desktop handles silently.
