HeimWall

Lightweight macOS app catching leaked secrets before they reach AI coding assistants

Desktopfreemiumglobal

A lightweight macOS app that detects leaked secrets, credentials, and PII just before they are sent to AI coding assistants like Cursor, Claude Code, and Copilot. It runs entirely on-device with 47 hand-written detection rules that flag potential leaks in milliseconds, does not upload prompts, and is free for individual engineers.
