VampireLib
VampireLib is a Fabric library mod by oliviathevampire that supplies shared base classes, registry helpers and datagen utilities for other mods.
What it does
Custom villager professions with their own workstations and trades are provided as base classes, so a mod can add a profession without writing that plumbing itself. Some GUI utility classes and a set of datagen classes are included as well.
The registry side covers two areas. A Registry Helper class simplifies registering objects, and a Wood Registry lets a mod register wood types and choose which ones to use. A Wood Type registry also lets code look up a specific wood type or loop through every registered one. A Convertible Blocks system converts blocks into customizable items.
VampireLib is open source under the Apache License 2.0, with public source code and an issue tracker. It is published for 1.16.4, 1.19.4 and 1.20.1, with 7.0.2 as the latest build for 1.20.1, and Fabric API is required. Both the server and the clients must run it, and snapshot builds are also published.

Use cases
Building a mod on shared code
A mod author can depend on VampireLib instead of rewriting registry, GUI and datagen helpers in each project.
Who it’s for: Mod developers who want ready-made base classes for villagers, wood types and registration, and players who run mods that depend on it.
How it compares
Registry Library needs only the server, with clients optional, and is under the MIT License for 1.19.2 – 1.20.2 on Fabric. Farest's API runs on client and server under the GNU Lesser General Public License v3.0 only, with files for 1.21 – 1.21.10. Exthylanes Extra Stuff is a client and server Fabric mod for 1.20.1 only and is not open source, as its All rights reserved license shows.
