MultiMC vs Thendrask Launcher

MultiMC is an alternative launcher for Minecraft that keeps multiple game instances separate. Each instance can have its own mods, resource packs, and saves, and users can import or export instances for sharing. It imports modpacks from Modrinth, CurseForge, FTB, Technic, ATLauncher, and FTB legacy, and includes a built-in modpack catalog. MultiMC also manages worlds and resource or texture packs, with controls for Java settings and runtimes. Color-coded logs provide extra diagnostic information, and users can stop Minecraft if it crashes or freezes. Automatic updates are supported. Downloads are available for Windows, macOS 10.13 or newer, and Linux distributions; Linux installations require Qt5 and may need distribution-specific packages. Designed to run in the background, including on older machines, MultiMC is free to use. A listed Patreon support option is priced on request; supporters get an app credit mention and a Discord role.

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. It supports separate instances and custom packs using Fabric, Forge, NeoForge, or Quilt, with dependencies installed automatically. 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 rolls back failed updates automatically. It also supports portable backups, broken-file verification, 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. The launcher is built with Electron and React and starts the official game without modifying Minecraft; it is not affiliated with Mojang or Microsoft. Modrinth and approved CurseForge are its only public provider modules. Download and use cost nothing under the MIT license; optional support tiers are $3 a month and 50.00 USD once for lifetime support.
