Lima launches Linux virtual machines (QEMU) with automatic file sharing, port forwarding (similar to WSL2) and built-in support for containerd (Other container engines can be used too).

The original goal of Lima was to promote containerd including nerdctl (contaiNERD ctl) to Mac users, but Lima can be used for non-container applications as well. Lima also supports non-macOS hosts (Linux, NetBSD, etc.).

Advantages compared to Docker for Mac?

Lima is free software (Apache License 2.0), while Docker for Mac is not.
