Thanks! The snapshot approach is exactly what we're using — UFFD (userfaultfd) to restore from a pre-booted snapshot, with on-demand page faulting so the VM responds before all memory is loaded. That's how we get to ~300ms.
1. Planning 2. Tools 3. Execution environment
Execution is often overlooked. Agents need somewhere to run code, install deps, write files, and continue workflows safely.
We ran into this while building agents, so we built Sandflare — sandboxes with memory that launch in milliseconds.
Agents can spin up environments, run code, and continue later without losing context.
