Download and Update Mods

Are you sick of constantly finding and re-adding that one mod you need? Prism Launcher interfaces directly with Modrinth and CurseForge and can download and update individual mods in addition to modpacks.

Minecraft Instance Management

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

Prism Launcher can help. Each Minecraft instance has its own folder, with completely separate mods, resource packs, and settings for each instance.


Instance Settings

Lightweight and Customizable

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