Features

What Prism Launcher keeps in separate chambers

Modpacks, mods, isolated instances, and a quiet Qt interface — shown as they appear in the app.

Modpacks

Modpack wells

Prism pulls modpacks into clean instances so you are not managing zip debris by hand. Browse, install, update, and read changelogs from one sheltered flow.

New Instance dialog browsing Modrinth modpacks with Fabulously Optimized selected — Draw packs from Modrinth or CurseForge without leaving the chamber

Modrinth pack information panel with update version dropdown and changelog — Refresh packs and read changelogs beside still water

Mods

Mod shelves by instance

The mod you need should not vanish between worlds. Prism speaks to Modrinth and CurseForge per chamber — search, queue updates, and confirm version steps before applying.

Download mods window searching Modrinth with Iris Shaders selected — Search both platforms from a single sheltered dialog

Confirm mod selection list showing version bumps from Modrinth and CurseForge — Review every version step before the chamber shifts

Instances

Vaulted instance lines

Run multiple Minecraft profiles with independent loaders, settings, and configs. Switch chambers without collisions across Fabric, Forge, Quilt, and vanilla.

Prism Launcher main window with Fabric, Forge, Quilt, Vanilla and grouped modpack instances — Group loaders and packs on one calm board

Instance version panel listing LWJGL, Minecraft, and Quilt Loader with install actions — Swap loaders and component versions per vault

Interface

Light surface, deep control

No embedded browser shell. Prism uses Qt, asks little of your system, and supports custom themes and menu layouts.

Prism Launcher dark UI with instance grid and launch sidebar for HexMC — Qt interface with launch controls beside your library

Prism Launcher instance library with grouped modpacks and custom visual accents — Shape your library without a heavy browser shell
