Local-first runtime firewall for AI coding agents
HOL Guard provides a checkpoint for AI agents, letting you allow, ask, or block risky actions before they run. It monitors actions such as destructive commands, secret access, software installs, and data movement, and records each event for later review. On supported integrations, Guard can stop operations like deleting files, reading cloud credentials, or sending data to external sites, while permitting normal tasks such as building projects. The tool runs on your computer, so your files never leave your machine, and it is free to start with optional Guard Cloud plans for cross‑device decision history and shared policies. HOL Guard is open‑source, with release history and verified contributors listed, and includes a plugin scanner that auto‑detects extensions, computes trust scores, and offers CI integration via GitHub Actions. It aims to help developers place a safety layer between their AI agents and the host system, catching mistakes before they cause harm.
