Rookhold

Sandboxed runner for short-lived AI-generated code with hard limits and verifiable receipts.

Servicefreeglobal

Rookhold is a self-hosted sandbox service for running short-lived, untrusted code (Python, Node, Bash) that an AI agent, evaluator or automation needs to execute without risking the host machine. It enforces hard time, memory and output limits, isolates the job with a gVisor boundary, and returns a verifiable receipt of the run, with a CLI, SDKs and an MCP adapter for agent hosts.
