zei.sh is a cloud platform providing ephemeral microVM sandboxes (Firecracker and Cloud Hypervisor) for AI agent execution. Clone, branch, and snapshot environments, built for reproducible agent runs, untrusted code execution, and evals.
Currently in public beta (v0.1), with a TypeScript SDK, an HTTP API, SSH/WebSSH terminal access, and real-time metrics and logs dashboards.
Highlights:
- 124ms VM boot, millisecond-scale environment cloning via CRIU-based snapshots.
- Distributed control plane: regional control plane, worker node daemons, WireGuard mesh networking, TLS/SNI ingress, and internal DNS resolution, deployed across a global edge network (3+ regions).
- Self-healing machine lifecycle via a finite state machine: machines reconcile back to desired state on crash or failure without operator intervention. Distributed state replicated across nodes via gossip-based SQLite, no etcd/Consul dependency.
