Ex0 Browser

🚀 What's New in v1.2.0: Native Password Vault & Pro Dark Reader

Exo-Browser takes a massive leap forward in daily usability, security, and aesthetics. We've replaced experimental features with rock-solid, production-grade systems!

• 🔐 Native Password Vault & Autofill: Built directly into the Chromium core using isolated IPC tunnels (exo-tab-preload). It intelligently detects login forms, displays a sleek overlay toast to save your credentials, and autofills them on your next visit—all encrypted locally with zero cloud exposure.
• 🌙 True Dark Mode (Powered by Dark Reader): Say goodbye to weird color inversions and midnight white-screen flashbangs! We integrated a professional Dark Reader engine that renders websites in deep, clean blacks instantly without breaking page layouts.
• 📦 Modular Plugin Engine: Continue building and installing custom extensions with drag & drop .zip installation and sandboxed API execution via the window.exo namespace.

Note for Builders: The open-source YouTube Enhancer plugin and the new v1.2.0 installer are available right now on our Discord and GitHub Releases!

Exo-Browser 🚀

Developed by Ex0 Studios
