QuestZ
by Globox1997
QuestZ lets server owners and players build a main quest line for Fabric 1.21.1 with an in-game editor, opened from the quest screen.
What it does
The mod enhances the vanilla advancement system by reusing its quest structure as a simple, single main quest line. Quests are created inside the game with a provided editor, so no data files need to be written by hand. The editor is switched on from a control in the quest screen and needs operator rights and creative mode before it can be used.
QuestZ runs on the client and the server, so both the server and every player need the mod installed. It is developed for Fabric only, and the author has stated plans for a Forge version without a date. Installation also requires Cloth Config API and Fabric API, which must sit next to QuestZ. The source code, issue tracker and wiki are publicly available, and the code is under the MIT License, so the project is open source.
The project was started a couple of years before its first release on 2026-02-26, and the author has kept it going since. The current Fabric file, 1.0.1+1.21.1, was published for 1.21.1 on 2026-03-21. No other game version is listed.
