The author uses BubbleWrap (bwrap), a lightweight Linux userspace sandboxing tool, to isolate dev environments and LLM coding agents without the overhead of VMs or Docker. The approach mounts only necessary host filesystem paths, mostly read-only, so a rogue agent or malicious dependency has limited blast radius. The key motivation is that LLM agents are now capable enough to run unsupervised, making containment practical and worthwhile.

BubbleWrap your dev env and agents
Developer sandboxes LLM coding agents with BubbleWrap, a lightweight userspace containment tool that limits blast radius from rogue agents without VM overhead—treating unsupervised AI agents as a security frontier requiring runtime isolation.
