Download Prism Launcher – Feature-Rich Minecraft Instance Manager

Prism Launcher is a free, open-source Minecraft launcher and instance manager that gives players and modpack creators full control over their Minecraft installations. Forked from MultiMC, it supports creating separate, isolated instances of Minecraft with different versions, mod loaders, and configurations — making it ideal for managing multiple modpacks side by side.

It integrates directly with CurseForge and Modrinth, allowing users to browse, install, and update modpacks and mods without leaving the launcher. Prism Launcher supports all major mod loaders including Forge, Fabric, Quilt, and NeoForge, and can manage Java installations automatically to ensure compatibility with older and newer Minecraft versions.

Designed with the community in mind, Prism Launcher is actively developed and maintained as a fully open-source alternative to official and proprietary Minecraft launchers. It runs on Windows, macOS, and Linux, and supports offline mode for users without a constant internet connection.
