Thendrask Launcher is a free, open-source desktop launcher for Minecraft modpacks, with separate instances, mod loader choices and Java runtime management. Users can browse approved Modrinth and CurseForge catalogues or import MRPACK and CurseForge ZIP files. Custom instances can use Fabric, Forge, NeoForge or Quilt, with dependencies installed automatically. The launcher downloads Java runtimes for each Minecraft release and also accepts custom Java paths. Before updates, it snapshots packs and verifies required files; failed updates roll back automatically. Users can also make portable backups, check for broken files and create sanitized diagnostic bundles. Friends can be added by code to view who is online and what they are playing. Windows is available, while macOS and Linux are in public beta. Thendrask Launcher uses Electron and React, and launches the official game without modifying Minecraft. Download and use are free under the MIT license. Optional project support costs $3 monthly or $50 lifetime.
