SmolVM is an open-source local sandbox for AI agents on macOS and Linux.
I started building it because agent workflows need more than isolated code execution. They need a reusable environment: write files in one step, come back later, snapshot state, pause/resume, and increasingly interact with browsers or full desktop environments.
Right now SmolVM is a Python SDK and CLI focused on local developer experience.
Current features include:
- local sandbox environments
- macOS and Linux support
- snapshotting
- pause/resume
- persistent environments across turns
I’d love feedback from people building coding agents or computer-use agents. Interested in what feels missing, what feels clunky, and what you’d expect from a sandbox like this.
