I found a Minecraft server project that is really focused on using a custom launcher instead of public mod platforms or generic launchers.
The main point is making it easier for players to get in fast and making things feel more professional. The launcher setup is meant to give better control over updates and add integrated authentication.
It can also handle Java versions and check files so the game is ready before you join. It also connects players to news the shop and the community in one place.
Why Servers Are Ditching Public Launchers
