Introducing HruHruLauncher — a custom Minecraft launcher written in Python with PySide6

🚀 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.

🧰 Tech stack and features

• 🐍 Python 3.10+
• 🧩 PySide6 – custom widgets, light/dark themes, animations
• 🌐 minecraft-launcher-lib – handles authentication, version downloads, launching
• 🧵 QThread-based worker system – keeps UI responsive during background tasks
• ⚙️ Modular codebase: core/, ui/, config/, utils/
• 🗃 Settings manager using JSON
• 🌍 Localization support (via resources.py)
• 💡 Custom download threads, UI state updates, error handling

🎯 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.

🛠 Try HruHruLauncher

It’s open-source and I’d love your feedback, ideas, or even small contributions!
