Not really seeing what's amazing about this. It looks like something very similar to what Fly already offers, just ad-hoc and snapshottable. Still Firecracker underneath.
I've been wanting to sandbox Copilot/Claude Code for a while, but I don't want to pay for a PaaS just to do that. I want to run the sandbox on my M4 chip instead of needing a constant internet connection to run code on an anaemic remote CPU.
