Prism Launcher vs Shard Launcher

Prism Launcher is a free, open-source Minecraft launcher for creating and managing multiple installations on Windows, macOS, and Linux. Separate instances can keep their own settings, mods, and resource packs. It installs modpacks from CurseForge, Modrinth, Technic, FTB, and FTB Legacy, and can update them. Individual mods from CurseForge and Modrinth can be installed with loader and game-version matching. Forge, Fabric, Quilt, and LiteLoader support one-click installation. Prism includes a built-in modpack catalog, Java runtime management, game log access, menu customization, and themes. On Windows, macOS, and Linux, version 9.0+ can detect and download an appropriate Java version, though availability varies by package. The macOS build requires Monterey or later; older versions are unsupported. Flathub is the primary Linux distribution method, and official AppImage builds are listed for x86_64 and ARM64. Prism is licensed under GPL-3 and supports free redistribution; the project states that it is not affiliated with Mojang or Microsoft.
