6 sandbox options for running agent-written code, from Docker to Firecracker
SuccotashKnown4766 · reddit · 2026-11-02
A practical rundown of where to execute agent-generated code without risking host credentials: local Docker (no network, mounted scratch dir, but only a light boundary since containers share the kernel), E2B hosted sandboxes with agent-loop SDKs, Modal Sandboxes (GPU access), Daytona, Vercel Sandbox for microVMs next to your app, and self-hosted Firecracker or gVisor for strong isolation at scale. Universal advice: block outbound network by default and set CPU and time limits.
