Code Verify: An open source browser extension for verifying code authenticity on the web

What this post added

Introduced Code Verify, an open-source browser extension that automatically verifies the authenticity of web code served to users. This enhances security for web applications like WhatsApp Web, Messenger, and Instagram Web by comparing the code running in the browser against a cryptographic hash source of truth verified by Meta and published via a partnership with Cloudflare. The extension provides real-time alerts (green, orange, or red) to users if inconsistencies are detected, ensuring the code hasn't been tampered with. The open-sourcing of Code Verify aims to encourage adoption by other services and foster community contributions.
