Modpack wanderers
ATM, Create, and shader-heavy packs each live in their own dimension with dedicated Java and RAM — no accidental crossover.
Step through the rift

One gateway. Every dimension.
Each instance is its own Minecraft dimension — mods, Java, and worlds sealed behind a boundary. Cross between them from a single portal without bleeding setups together.
The gateway
Prism Launcher is an open-source gateway for Minecraft. It routes you into separate dimensions — each instance — without dragging a heavy browser shell along.
Every dimension keeps its own version, loader, Java path, worlds, and packs. Hop from vanilla to Fabric, Forge, Quilt, or a 200-mod pack without files crossing the rift.
Note: prism-launcher.org is a community mirror, not the official prismlauncher.org project site.
Cross to 11.0.3Pack crossings
Pull packs through the rift instead of hand-zipping folders. Prism fetches, installs, and updates Modrinth and CurseForge content so you spend less time at the threshold.
Mod shards
Lost the same mod in three dimensions? Prism reaches Modrinth and CurseForge per instance so installs and updates stay on the correct side of the boundary.
Dimensions
Spin up isolated Minecraft dimensions with their own mods, RAM, and configs. Step through the gateway to another setup without collapsing the one you left.
Portal shell
No embedded browser required. The Qt shell stays lean on CPU and RAM, and custom themes let you reshape the portal interface around your dimensions.
Who crosses
ATM, Create, and shader-heavy packs each live in their own dimension with dedicated Java and RAM — no accidental crossover.
Native builds, AppImage, or Flatpak — pick the route that opens the portal on your distro.
Import old instances through the rift, then add CurseForge and Modrinth without copying jars by hand.
Forge, Fabric, Quilt, and NeoForge dimensions side by side — never one shared .minecraft folder.

Transparency
Source ships under GPL-3. Logo assets use CC BY-SA 4.0. Builds cover Windows, macOS, and Linux — Flatpak and AppImage included.
Windows SmartScreen may appear because the project has not purchased a Microsoft code signature — common for unsigned open-source gateways. Read the trust page before you step through.
Trust and security detailsEchoes from the rift
Pack hopper
Six dimensions on one machine. Modrinth updates land without folder archaeology. No Overwolf shell in the gateway.
Flatpak traveler
Linux install opened the portal cleanly. My Fabric shader dimension never leaks into the Forge kitchen-sink rift.
MultiMC import
Old instances crossed over intact. Built-in CurseForge plus Modrinth is why I stayed on this side of the rift.
Family setup
Microsoft login via device code worked. Stable on Windows 11 after one SmartScreen allowlist.
