What Vercel is
- Firecracker microVMs on the same infrastructure as Vercel
Functions, via an SDK for Vercel apps - Now persistent by default: filesystem snapshots on stop, resume, and an explicit fork call
- Custom images from Vercel's registry, plus a per-sandbox egress firewall with a domain allowlist
- Active-CPU billing suits waiting agent workloads; the catch is a single US region
