Show HN: Run coding agents in a sandbox locally
github.comLaunching SmolVM -- run claude and codex in sandboxed environment with full permissions worry free.
It sucks to “press enter and accept changes” every few seconds while using coding agents. We made it easy to isolate the agent coding environment from the host (laptops).
With a single command you get a claude/codex pre-installed sandbox ready with git credential to make you build a billion dollar business without making any mistake ;)
To give it a try, head to the open-source repo and install SmolVM then run: "smolvm codex start" or "smolvm claude start --mount ./my-project" for a quick experiment. I've been building SmolVM -- an open-source AI sandbox focused on making it easy to run agents securely on laptops and on-prem servers. Over last few weeks, we've improved speed, cold start, added pause/resume, host directory mounting, and a bunch of features. You can use it with a CLI to manage sandboxes, run coding agents or use with Python SDK to build custom agent harnesses.
