🚀 No Chromium. No Electron. Just pure native performance.

🔍 Overview

Are you tired of your messaging app consuming 2GB of RAM just to tell your mom you'll be home late for dinner? Do you enjoy the feeling of your laptop fans reaching terminal velocity because you opened a group chat?

NanaonanApp is a WhatsApp desktop client that connects to WhatsApp's servers using the whatsmeow library. Unlike official WhatsApp Web/Desktop that uses a browser engine (Chromium), this application is built natively using:

• Qt6/QML for the user interface
• C++ for application logic and data models
• Go for WhatsApp protocol implementation (via whatsmeow)
• CGo bridge to connect C++ and Go

🚧 Strategic Feature Postponement (The TODO List)

Our TODO.md is not a list of failures. It is a Roadmap of Future Greatness.

By not implementing 80% of WhatsApp's features yet, we have achieved a level of Minimalism™ that Silicon Valley can only dream of. No stickers? That's "Visual Detox Mode". No group settings? That's "Anarchy-Driven Development".
