## What it is
Prism Launcher is an open-source, cross-platform Minecraft launcher for managing multiple isolated game instances, each with its own mods, resource packs, and settings. It is a fork of MultiMC built with Qt, integrating with Modrinth and CurseForge for one-click mod and modpack installation.

## Use cases
- manage multiple minecraft installations with separate mods and settings
- install modpacks from curseforge or modrinth
- install fabric forge or quilt mod loaders with one click
- update individual mods automatically for my game version
- manage minecraft worlds resource packs and shader packs
- lightweight open-source alternative to the official minecraft launcher
- upload minecraft crash logs to mclo.gs

## When to choose
- you play with multiple modded instances or modpacks and need isolation between them
- you want integrated Modrinth/CurseForge mod and modpack management
- you need a free, redistributable launcher on Linux, Windows, or macOS

## When to avoid
- you only need vanilla Minecraft and are happy with the official launcher
- you need console-only or headless server management rather than a desktop GUI
- you require a launcher endorsed by or compatible with MultiMC's official project
