Code Verify

An extension to verify the code running in your browser matches what was published.

Code Verify is an open-source browser extension designed to verify that the web-based versions of WhatsApp, Facebook, Instagram, and Messenger you use are authentic and unmodified. Unlike mobile apps that have built-in security verification, web clients run JavaScript code which could potentially be altered by malicious actors.

This extension scans the JavaScript code served on these sites and compares it with a publicly posted source of truth hosted via Cloudflare. If any discrepancies are found, Code Verify alerts you immediately, ensuring that you are not subjected to tampered or spying versions. Automatically updating its verification sources keeps your protection current with each app update.

By pioneering web binary transparency through open-source development, Code Verify empowers security-conscious users with trustworthy verification and offers a model other web apps can adopt to enhance online privacy and security. Experience the peace of mind that comes with knowing your web apps are exactly what they claim to be.
