Check out LXC and the wider Incus set of projects: https://linuxcontainers.org/incus/.

Running IncusOS on some local hardware with ZFS underneath is a phenomenally powerful sandbox.

Yeah I can make an lxc container called "ai" that has an ssh read key and then a few pre cloned projects. When I want to work I can clone and start it then get the same effect on my own hardware and for free. Just need a small little wrapper to make this a bit more streamlined
