OpenSandbox: Build AI Agents That Actually Execute Code (Free & Open Source) The Problem Every AI Developer Faces You want to build an AI coding agent. You have the LLM. You have the prompt engineering. But here's the uncomfortable truth: your agent can't actually do anything. It can write code. It can explain code. But execute? Run tests? Interact with a browser? That requires infrastructure. And most options are either: Expensive : Third-party sandbox APIs charge per-minute (e.g., E2B at $0.04/min) Complex : Rolling your own Docker isolation takes weeks of devops work Insecure : Running agent code on your own infrastructure risks system compromise This is the "execution layer" problem in the AI agent stack—and Alibaba just open-sourced the solution .
