Download & Update Mods

Are you sick of finding and adding that one mod you need? Prism Launcher is able to download & update individual mods from outside of modpacks using Modrinth and CurseForge.

Minecraft Instance Management

Did your settings ever reset after launching an older version? Did you ever accidentally break a world because you opened it in an old version? Are you tired of manually switching mods for different versions, installing modloaders?

Prism Launcher can help. Each Minecraft instance has its own folder, with separate mods, resource packs and other things.

Lightweight & Customizable

You don't need an embedded web browser as a game launcher. Prism Launcher uses the Qt toolkit, which requires little system resources. Prism Launcher also lets you customize the menu and supports custom themes.
