Flint Quests
by kas
Flint Quests is a Fabric library for building questing systems, with a custom questline UI modeled on FTB Quests and an API for other mods to hook into.
What it does
A quest system is built from quests and their dependencies, and Flint Quests provides the framework to define them, track progress and present them in a custom interface. Authors who want a questline without assembling an entire modpack around one can use the system as a single mod. Editing and non-editing modes can be switched, so a finished quest set can be shipped inside a jar and played without the editor being active.
The project aims to make a questing system accessible to mod developers through an API that other mods can hook into with little setup. Quests are intended to replace the flat progression of vanilla advancements with something the author can shape. The mod uses nested jars for its dependencies, so it ships as one file. Flint Quests requires Fabric API, and the mod is published for Fabric only, for 1.21.11.
Key features
Custom quest interface
A quest screen styled after FTB Quests lets players browse chapters, tasks and progress in one view.
Editing and play modes
A mode switch turns the editor on or off, so the same build can be authored and then played.
Embedded quest data
Quest content can be packaged into the mod jar itself, so a finished questline ships as one file.
Developer API hooks
Other mods can attach to the questing system through its API, without building their own quest handling.

Use cases
Standalone questline
A modder can add a questline to a single mod instead of building a full modpack with its own questing system.
Pack authoring
Pack makers can edit quests in the editor mode and then switch to play mode before release.
Who it’s for: Mod developers who want a questing system for their own content, and modpack authors who want quests that are not limited to vanilla advancements.
How it compares

Questforge is a Fabric mod for 1.21.11 that is not open source and is licensed as All rights reserved, with client and server both needing it. Flint Quests is distinct in that it is a client-required mod with an optional server side, released under a custom license.
