Diarea

Diarea is a defensive security agent that scans frontend code and applications to detect exposed keys, source maps, API maps, and debug globals.

Diarea reads frontend applications to identify leaked secrets, source maps, client-side logic, hydration payloads, API maps, AI system prompts, and other sensitive data. It scores the damage on a scale from sealed to gushing and provides one-line fixes for each finding. The tool runs locally via a CLI, a browser extension, a model context protocol server, or a CI action, keeping all data secure. It offers static scanning via jsdom and live scanning via Playwright to inspect deployed URLs and build outputs. Designed for developers and security teams, it prevents automated reverse-engineering tools from exposing private code and internal configurations.
