Instead of Prism Launcher
Prism Launcher alternatives
Prism Launcher is a free, open-source Minecraft launcher for keeping installations separate, with their own mods, resource packs, and settings. It supports Forge, Fabric, Quilt, and LiteLoader, and brings modpacks from CurseForge, Modrinth, Technic, FTB, and FTB Legacy. It also installs individual mods from Modrinth and CurseForge with loader and game-version matching, manages Java, and offers themes, update support, and game-log access. It runs on Windows, macOS, and Linux; the macOS build requires Monterey or later.

A different launcher may be a better fit if its supported devices, game resources, or content sources better match how you play. Most options here overlap with Prism on separate instances, modpack imports, multiple loaders, Java management, catalogs, and updates, so those basics alone may not distinguish them. Compare the specifically described pack sources and resource types, and consider whether mobile support or public development matters. Also weigh Prism's custom themes, API controls, and log tools against any concrete additions in another launcher before moving your installations.
