PolyMC is an open-source custom launcher for Minecraft, forked from MultiMC, that lets users create and manage multiple isolated Minecraft instances with separate mods, resource packs, and settings. Built with Qt, it supports installing modloaders (Forge, Fabric, Quilt, LiteLoader) and downloading mods and modpacks from Modrinth, CurseForge, Technic, and FTB.
Use cases
- manage multiple minecraft installations with separate mods and settings
- install forge or fabric modloaders easily
- download and update mods from modrinth and curseforge
- install modpacks without manual setup
- keep old minecraft worlds safe from version mismatches
- kill frozen minecraft and view game logs quickly
- run a lightweight open-source minecraft launcher on linux
When to choose
- you play multiple Minecraft versions or modpacks and need isolated instances
- you want a lightweight, free, redistributable launcher without an embedded web browser
- you need one-click mod and modpack installation from Modrinth or CurseForge
When to avoid
- you only ever play one vanilla Minecraft version and the official launcher suffices
- you need features from launchers with built-in social or marketplace features
- you require a launcher officially endorsed by MultiMC
