smol machines

smol machines provides lightweight virtual machines that run identically across your laptop, a managed cloud service, or self-hosted servers. Each workload gets hardware isolation with its own kernel via MacOS Hypervisor, Linux KVM, or Windows Hypervisor Platform. The same SDK and portable .smolmachine artifact work everywhere, letting you develop locally and deploy without changes.

Designed for AI agents, reinforcement learning environments, and untrusted code sandboxing, smol machines offers unique features like branching running VMs into copies, checkpointing machine state, and elastic memory that only commits what the guest actually uses. The open-source runtime supports any OCI image, boots in under a second, and can be embedded directly into applications via Node, Python, or Rust SDKs.
