🚀 What is this project?

As a personal challenge, I’ve been building an open-source Minecraft launcher completely in Python. It uses PySide6 for the UI and public APIs for version handling and launching.

The goal was to create a modular, clean, and responsive launcher that could one day support both Vanilla and modded Minecraft.

🎯 Why I made this

I love Minecraft and Python, and I wanted to combine the two while also learning more about Qt, multithreading, and architecture. There are many launchers out there, but I wanted to build something from scratch to really understand how it all works.
