Smol Machines (smol machines, inc.) is a Y Combinator-backed developer infrastructure company building portable, self-contained Linux microVMs. Its open-source `smolvm` engine and `smol` CLI (both Rust, Apache-2.0) boot hardware-isolated virtual machines from any OCI image in under 200ms — on a laptop, in the smolfleet cloud, or self-hosted — with no daemon and no Docker. The same Machine API runs locally as an in-process microVM or against the hosted smolfleet control plane at api.smolmachines.com, so teams sandbox untrusted code and AI-agent workloads, ship stateful `.smolmachine` artifacts, and deploy machines across a cluster without changing a line. Node and Python SDKs (`smolmachines`), a local REST API, and a cloud REST API are all public.
