What Thendrask Launcher is
Thendrask Launcher is a free, open-source desktop launcher for Minecraft modpacks. Users can browse approved Modrinth and CurseForge catalogues or import MRPACK and CurseForge ZIP files. Separate instances and custom packs are supported, with Fabric, Forge, NeoForge, or Quilt and automatic dependency installation. Java runtimes are downloaded for each Minecraft release, and users can set custom Java paths. The launcher verifies required files, snapshots packs before updates, and automatically rolls back failed updates. It also supports portable backups, broken-file checks, and sanitized diagnostic bundles. Users can add friends by code to see who is online and what they are playing. Windows is available, while macOS and Linux are in public beta. Built with Electron and React, the launcher downloads modpacks and starts the official game without modifying Minecraft; it is not affiliated with Mojang or Microsoft. Its only public provider modules are Modrinth and approved CurseForge. Download and use are free under the MIT license; optional project-support tiers are $3 monthly and $50 lifetime.
