It's hard to tell what this is or how it compares to other things that are out there, but what I latched onto is this:

> Freestyle is the only sandbox provider with built-in multi-tenant git hosting — create thousands of repos via API and pair them directly with sandboxes for seamless code management. On top of that, Freestyle VMs are full Linux virtual machines with nested virtualization, systemd, and a complete networking stack, not containers.

It makes me think of the git automation around rigs in Gas Town: https://steve-yegge.medium.com/welcome-to-gas-town-4f25ee16d...

Edit: I realize the Loom is a way to look at it. Loom interrupted me twice and I almost skipped it. However it gave me a better idea of what it does, it "invents" snapshotting and restoring of VMs in a way that appears faster. That actually makes sense and I know it isn't that hard to do with how VMs work and that it greatly benefits from having only part of the VM writable and having little memory used (maybe it has read-only memory too?).

So the snapshotting tech is actually 100% independent of Git.

Git is useful for branching vs forking (IE you can't merge two VM forks back together), but all the tech I showed in the Loom exists independently from Git.

The hard part of it was making the VM large and powerful while making snapshotting/forking instant, which required a lot of custom VMM work.
