Colima

Docker Desktop without the licensing headaches or resource bloat. Colima runs containers on macOS using a lightweight VM that idles at 350MB — compared to Docker Desktop's 1.2GB. Install via Homebrew, run colima start, and your existing Docker CLI just works.

Docker Desktop is the default but its licensing changes pushed many teams to alternatives. Rancher Desktop offers Kubernetes integration. Podman Desktop is Red Hat's container alternative. Lima is the VM layer Colima is built on.

The multi-runtime support is clutch: switch between Docker, containerd, and Incus without reinstalling anything. You can run multiple isolated environments simultaneously with separate resource allocations. Dev Containers, docker-compose, and all your existing workflows work unchanged.

The catch: Colima occasionally needs manual intervention that Docker Desktop handles silently — socket permissions, DNS resolution, volume mount quirks. File sync between macOS and the Linux VM can be slower than Docker Desktop's virtiofs. And there's no GUI — if you want a visual container manager, you'll need to pair it with Dockge or Portainer.
