If you're referring to the claim that you can say goodbye to VMs, it's false/misleading advertising. It still runs a VM, just like Docker Desktop does.

  Running all your instances in separate VMs vs using a single VM to host containers is a completely different paradigm, especially when it comes to performance. This is even more true for performance between instances. So I personally don't find "say goodbye to VMs" to be misleading.

    >Running all your instances in separate VMs But Docker Desktop doesn't create a VM per container. Or have I misunderstood?

      Correct, and neither does OrbStack. Clarification here: https://news.ycombinator.com/item?id=35743597 https://news.ycombinator.com/item?id=35743597

  (dev here) Hey, to clarify: "Say goodbye to slow, clunky containers and VMs" refers to the fact that we support running both Docker containers and Linux machines, not that the Docker engine doesn't use a VM under the hood. And yes, there is still a VM, but the experience and architecture are very different from traditional full Linux VMs that we're describing with "slow, clunky".
