Prism Launcher vs X Minecraft 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.

X Minecraft Launcher (XMCL) is a free, open-source launcher for managing Minecraft game resources and separate game instances. It runs on Windows, macOS, and Linux. Users can manage modpacks, resource packs, mods, shader packs, and other resources, with instances covering Forge, Fabric, Quilt, NeoForge, OptiFine, and LabyMod; Bedrock support is experimental. Its marketplace gathers modpacks and projects from Modrinth, CurseForge, and FTB. The launcher can import modpacks, manage Java runtimes, and update automatically. Mod tools include dependency inspection and custom groups. Account options include Microsoft, offline, Ely.by, and LittleSkin authentication. World tools let users preview saves, select, copy, or delete chunks, and view structures in 3D. Users can export modpacks and local server files from the launcher. Telemetry is off by default and is processed only if enabled in settings. XMCL says it does not handle Microsoft account passwords, credentials, or session tokens. It is an independent project and is not an official Minecraft product or associated with Mojang or Microsoft.
