1) Runs containers / VMs ("linux machines"). Here you get a linux instance with access to your complete filesystem (everything is mounted), similar to I guess WSL
2) Full docker compatible + docker-compose
3) As of this week kubernetes support
Everything is blazing fast to start (think 100-200ms). Aside that, there's one thing that's awesome: networking.
Every container gets a unique IP. No more portmapping.
Every containers also gets a unique hostname (+ip) -> testapp.orb.local
Every every docker-compose gets a unique subdomain -> web.testcompose.orb.local
And a comparison: https://docs.orbstack.dev/compare/docker-desktop
I think you'll find something you like in there :) To name a few: Performance, CPU usage/power efficiency, automatic domain names for containers, access to volumes and image files from macOS, native app, and more.
