No Nether
by 1111w
No Nether blocks travel into the Nether dimension by stopping players from entering it through a Nether portal.
What it does
Once the datapack is active, a Nether portal no longer sends players into the Nether. The mod works by a data pack placed in the world's datapacks folder, so no code runs in the game itself, and a reload of the world is needed before the change applies. It is server required, with client optional, so servers carry the change and players may leave it out.
The mod is published for Fabric, Forge, NeoForge and Quilt, with the data pack also offered for server platforms. Files cover 1.21.5 – 1.21.11, and the latest build for every loader is 1.21-Plus+mod for 1.21.11, released on 2025-10-07. It is released under a custom license and is not open source.
Key features
Portal entry blocked
Players who use a Nether portal are prevented from entering the Nether dimension.
Data pack delivery
The change is delivered as a data pack, which is placed in the datapacks folder of the world directory.
Automatic activation
After the world is reloaded, the data pack activates on its own, with no setup screen or command.
Light install
The file is small and needs only to be copied into the world, which keeps the installation simple.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Servers without the Nether
Server owners who want to keep players out of the Nether dimension can install the data pack on their world.
Who it’s for: Server owners and world administrators who want to block Nether travel in a survival or multiplayer world.
How it compares
Custom nether portal size is a Fabric client and server mod under All rights reserved, which changes portal dimensions and is not open source. Configurable Nether Portals is server-side only and open source under the MIT License, but is published for 1.19 – 1.20.2 and is not built for the current versions. End Portal Break is server required with client optional and covers 1.21.5 – 26.3 on all four loaders, but it changes End portals rather than blocking the Nether.
