Nido — Fast, Simple VM Sandboxes for AI Agents (Temporary & Persistent)

Nido is an open-source tool that provides fast, retro-futuristic virtual machine sandboxes (VMs) for AI agents. Built on QEMU, it allows developers and AI engineers to rapidly spawn, manage, and destroy real, unconstrained VMs within seconds. Nido is designed for safe, repeatable experimentation and execution of autonomous AI code, supporting both ephemeral and persistent environments, and can be driven by language models via the Model Context Protocol (MCP).
