What it does
SmolVM gives AI agents a disposable computer: a hardware-isolated microVM that boots in hundreds of milliseconds, runs arbitrary code or a full browser, can mount host directories, snapshot/restore, and disappear when the task ends. One API covers Firecracker (Linux), QEMU (macOS), and libkrun.
Docs body (live): “SmolVM gives AI agents their own disposable computer. Each microVM boots in milliseconds, runs any code or software you throw at it, persists files and state across sessions, and disappears when you’re done — built for scale in production.”
Distinct from catalog peers:
| Peer | Difference |
|---|---|
| E2B | Hosted cloud sandboxes. SmolVM is local/self-host multi-VMM |
| CubeSandbox | E2B-compatible self-host service (cluster API). SmolVM is an SDK/CLI on the machine |
| forkd | Firecracker CoW fork/BRANCH fan-out. SmolVM is create/run/snapshot of a single disposable VM |
| OpenSandbox | K8s/runtime abstraction + MCP |
| Clawk | Local hypervisor VM for one coding agent on a desk (macOS). SmolVM is Linux+macOS+Windows guests with a unified SDK |
