Install a modpack in Prism Launcher by importing it as a new instance, then launching it unchanged first.

Importing a pack

Add the pack as a new instance from its file or source, let dependencies download, and launch it once before changing any mod.

Overview

Download and update modpacks from Modrinth, CurseForge, FTB, Technic, and ATLauncher directly inside Prism Launcher on Windows.

Guide

Create a first Prism Launcher instance: pick a Minecraft version, launch vanilla, then customise it.

How-to

Add mods to a Prism Launcher instance: match the loader and game version, add one mod at a time and test.

Free and open source. Sign in with the Microsoft account that owns Minecraft, then create your first instance.
