Splitscreen Support
by pcal43
Splitscreen Support lets two or more players share one computer, each in a separate Minecraft window placed on screen by the mod.
What it does
The mod positions the game windows for local multiplayer. Pressing the Toggle Fullscreen key (F11) cycles the window through half-screen and quarter-screen layouts, and the chosen layout is saved so the window returns to the same place after a restart. Starting extra copies of the game places them automatically in split-screen arrangements.
The mod is meant to be used with a launcher that starts several accounts, such as PrismLauncher, and with a gamepad mod such as Midnight Controls so that each copy can be driven by its own controller. Fabric API is required on Fabric. The mod is client-side only, so servers do not need it, and it is open source under the MIT License. Files are published for Fabric and NeoForge across 20 release versions, 1.20.1 – 26.2.
Key features
Window positioning
Windows snap to half-screen and quarter-screen positions, so several copies fit on one display.
Fullscreen key cycling
The Toggle Fullscreen key steps a window through the available layouts without leaving the game.
Saved layouts
The chosen position is stored and restored when the game starts again.
Automatic arrangement
Additional game copies started on the same machine are placed into split-screen positions automatically.

Use cases
Couch co-op on one computer
Friends sit in front of a large display and each plays a separate copy of the game with their own controller.
Multiple accounts on one machine
A launcher such as PrismLauncher can start several legal accounts, and the mod arranges their windows.
Who it’s for: Players who run several Minecraft copies on one computer for local multiplayer, and launcher users who pair the mod with gamepad support.
How it compares
Gamepad Hotbar is a Fabric and NeoForge client mod under the MIT License, open source, for 1.21.1 – 1.21.11, and it changes the hotbar for controller use rather than window placement. Window Size is open source under the MIT License, client-side only, and covers 1.21 – 26.3 on Fabric, Forge, NeoForge and Quilt, so it reaches more loaders and versions while handling window size. Dark Window is a Fabric-only client mod for 1.21.1 with All rights reserved licensing and is not open source.
