flue

Flue is an open-source sandbox agent framework for AI/ML that enables developers to safely execute untrusted code and AI agent actions within isolated, ephemeral environments. It is designed for researchers and engineers building autonomous agents, offering fine-grained resource controls and network restrictions to prevent malicious or runaway behavior. Its interesting because it provides a production-ready, lightweight alternative to Docker for agent sandboxing, directly addressing the critical safety and security challenges in deploying autonomous AI systems.
