> docker desktop is pretty dead now that it's got restrictive licensing etc...

It would probably be nice to hear more about why you think this is! I've certainly heard of some having to move away from Docker Desktop.

However, at the scale where you need a license (250 employees or 10 million $ in annual revenue) it's not quite as big of an issue, especially at their current pricing per seat: https://www.docker.com/pricing/

> stick to standard open source tools like Colima etc...

Sticking to open source is a great idea!

I think mentioning that Colima runs on macOS and Linux only at the moment is also a good idea: https://github.com/abiosoft/colima

A large market share of the Docker Desktop installs are Windows in particular (since it's "the one way" how most install Docker nowadays, as opposed to not really needing a GUI or the supporting tools on Linux).

In another comment I mentioned Podman Desktop as a mostly viable alternative: https://github.com/containers/podman-desktop

Then there's also Rancher Desktop as well: https://github.com/rancher-sandbox/rancher-desktop

Regardless, it's nice to see reputable orgs behind the open source projects as well, which gives a bit more credence to their chances of surviving for the years to come.
