Portal Randomizer
by hiisuuii
Portal Randomizer replaces the End portal's eye-of-ender requirement with a set of 12 random items, making the End harder to reach or simply different.
What it does
Portal Randomizer is a Fabric minigame mod for the server side. When it runs, the End portal asks for 12 random items in place of the usual eyes of ender, so the route into the End changes from world to world. The selection is drawn from a pool of items rather than a fixed list, and the author notes that a datapack with a similar idea offers only about 30 different items, while this mod picks from a wider pool.
Only the server needs the mod, so players join without installing anything. It is built for Minecraft 1.21.8 alone, and the latest Fabric file is 1.0.1 for 1.21.8, published on 2026-05-29. Portal Randomizer is released into the public domain under the CC0 1.0 Universal license and is open source, with public links to its source code and issue tracker.
Key features
Random End portal cost
The End portal requires 12 randomly chosen items instead of the eyes of ender, so the recipe differs per world.
Wide item pool
Items are picked from a broad set rather than a short list, which keeps the requirement from repeating.
Server-side operation
Changes apply on the server, so players connect without installing anything on their own game.
Inspired by Portal Lock
The idea draws on the Portal Lock datapack, and the author credits its creators, Manchick and BatsPaladin4422.

Use cases
Challenge runs
Players who want the End to be less predictable can run a world where the portal requirement is unknown from the start.
Server events
Server owners can host a shared challenge in which every player must gather the same unfamiliar set of items.
Who it’s for: Server owners and players who run challenge worlds, where a fixed eye-of-ender recipe would be too familiar.
How it compares
Size Randomizer and Ultimate Randomizer Multiplier both run on Fabric and need to be installed on the client and server, and both are closed licensed under All rights reserved. Inventory Randomizer is also a client and server mod, but it targets 1.19.2, is licensed under the MIT License and is open source. Portal Randomizer works on the server alone and is open source under CC0 1.0 Universal, so it suits servers that do not want client installs.
