ElyPrism Launcher (1.21.11, 1.20.1) is a fork of Prism Launcher. It supports integration with Ely.by accounts, allowing players to log in and use Ely.by’s alternative authentication system while still supporting Microsoft (MSA) accounts.

Features:
- Uses OAuth2 for secure login, ensuring credentials are not sent directly to the launcher but processed through Ely.by’s official website, providing a limited-access token.
- ElyPrism Launcher uses Ely.by’s official Authlib patch, enabling skin display on all servers, even those without specific skin plugins.
- Allows creation and management of multiple Minecraft instances with separate mods, resource packs, shaders, and configurations.
- Integrates automatic downloading and updating of mods, modpacks, and resource packs from Modrinth and CurseForge, with support for automatic installation of modloaders like Forge, Fabric, Quilt, NeoForge, and OptiFine.
- Uses Qt toolkit for low system resource consumption.
- No DRM restrictions: Allows offline play without copyright checks.
