Prism Launcher vs RetroFE

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.

RetroFE is a free, open-source front end for displaying, selecting and launching games, videos and programs, commonly used for game emulation. Collections arrange games and menu items into systems and submenus, and can show media such as box art, screenshots, logos and videos. Layouts set the front end’s appearance, with the option for collections to use their own layouts. Launcher configuration specifies an executable and arguments for starting an emulator, application or game; per-game launcher settings can override a collection’s default. Controls such as up, down, select and back are configured in a controls file. Its game information database can hold details including year, manufacturer, genre and player count. Setup involves editing global settings and controls files, then adding or editing collections. Full releases include a 32-bit Windows executable and a 64-bit Linux executable. Windows requires a recent Visual C++ Redistributable for Visual Studio; some Linux distributions may require compiling from source. macOS users need to compile their own executable. Community-made themes are available for installation in the layouts directory, and the maker points users to forums and describes community support.
