GDLauncher vs Prism Launcher

GDLauncher is a free Minecraft launcher for creating and managing separate game instances on Windows, macOS, and Linux. Each instance can have its own mods and resource packs; users can group, duplicate, and share setups by code. It installs CurseForge and Modrinth modpacks with one click and sets up the mod loader and Java. Supported loaders are Forge, Fabric, NeoForge, and Quilt. The launcher can also create and manage Minecraft servers, with a live console, CPU and memory monitoring, player controls, and server mod installation. Import and export support for other launchers—including CurseForge, MultiMC, ATLauncher, Technic, Prism, Modrinth, and FTB—is marked as work in progress. The listed export formats are CurseForge .zip, Modrinth .mrpack, and GDLauncher .gdlpack. GDLauncher is free to use, with no premium tier or overlay, but access requires a valid, fully paid Minecraft Java Edition account. Its privacy statement says account email is shared in hashed form with Overwolf for personalized advertising; users can opt out in the app’s Privacy settings.

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.
