Paper Launcher

A clean Minecraft launcher. One big PLAY button, your profiles one click away, and mods from Modrinth without leaving the app.

It's a sketch for developers: the full source, ready to build on. There's no ready-made app yet, because logging in needs a Microsoft app ID approved by Mojang. Add your own and make it yours.
