Fullscreen Borderless
by qaut
Fullscreen Borderless is a Fabric client mod that switches Minecraft between borderless fullscreen and windowed modes from the main menu with one click.
What it does
The mod adds a button to the main menu that turns on borderless fullscreen without opening the video settings. Borderless fullscreen fills the monitor with the game window and removes the title bar, so switching away from the game takes effect at once and without a screen flicker, which makes alt-tabbing faster for players who multitask.
Its approach is to change the window behaviour through mixins and background processes that act on the window handle, rather than through a separate launcher. The mod is lightweight, and the author states that it is performance-friendly and that multi-monitor handling was improved. Because the button is a custom icon, it sits on the main menu and not inside a settings screen.
Installation needs only Fabric. It is a client-side only mod: players install it, and servers run without it. Files are published for 26.2 with the latest build 26.2.18, dated 2026-07-05, and the six release versions run 1.21.10 – 26.2, including 1.21.11 and 26.1.2. The code is under the MIT License, but the project is not open source in the sense of publishing its full source tree.
Key features
One-click borderless toggle
A button on the main menu switches between borderless fullscreen and windowed mode in a single click.
Instant alt-tab
Leaving the game to another window happens without the screen flicker common to standard fullscreen.
Custom menu icon
The toggle is drawn as a dedicated icon button added to the main menu instead of a text option.
Multi-monitor handling
The mod changes window placement so that borderless mode works across several monitors, according to the author.

Use cases
Who it’s for: Players who want to change between borderless and windowed display without visiting the video settings, mainly on Fabric with the 26.2 builds or the earlier 1.21.10 – 26.1.2 builds.
How it compares
WindowedFullscreen is a Fabric-only client mod for 1.21 – 1.21.11 with All rights reserved licensing and no open source code. Cubes Without Borders is a client-side only mod for 1.16.5 – 26.2 on Fabric, Forge, NeoForge and Quilt under the MIT License, and it is open source. Fullscreen Borderless runs on Fabric alone, so it offers fewer loaders but a newer range.
