Open-source sandboxes to run AI code, browser agents and computer-use

SmolVM is an open-source tool that provides AI agents with secure, disposable virtual machines that boot in 500 milliseconds for running untrusted code and browser automation. The lightweight sandboxes offer hardware-level isolation stronger than containers, allowing agents to safely execute AI-generated code, control browser sessions, and maintain state across multi-step workflows. Each virtual machine automatically destroys itself after use and includes network controls, snapshots, and integration with AI frameworks like OpenAI Agents and LangChain.
