Foil
Find vulnerabilities before they ship. 100% local AI.

Foil is an on-device AI security scanner for macOS that uses a locally-run LLM to scan source code for vulnerabilities without sending any data to the cloud. It ships with SecureReview-7B, a custom fine-tuned model optimized for Apple Silicon, and provides deep explanations and automated fix rewrites. The tool is installed via Homebrew and runs entirely offline.
Foil runs a custom fine-tuned LLM (SecureReview-7B) locally on Apple Silicon to scan code, reason about vulnerabilities, and generate fix explanations and rewrites entirely on-device.
