What is Agent Sandbox?
Agent Sandbox is an open-source Kubernetes project designed for AI agent code execution and “computer use” scenarios. It provides strong workload isolation (e.g., via gVisor and optionally Kata Containers) and lifecycle controls so teams can provision short-lived, restricted environments for tools, terminals, and code that agents generate. The goal is to reduce risk from non-deterministic agent actions while scaling to many concurrent sandboxes.
