Jaidev Library
by Jaidev
Jaidev Library is a Fabric library mod for 1.20.1 that other mods build on, and it is required by Heart Container and Bigger Arsenal.
What it does
Library mods like this one hold shared code that other mods reuse, so authors do not have to write the same routines again. Jaidev Library is server required and client optional: a server must run it, while players may leave it out. It is released under the MIT License and is not open source. Files exist for 1.20.1 only, with 1.0.5+fabric as the latest file, published in the beta channel on 2026-01-16.
Key features

How it compares
Registry Library is also a Fabric library, released under the MIT License and open source, with files for 1.19.2 – 1.20.2. The server must run it, while players may skip it, so either side can be the one that runs it. Simplify Tool Config Lib is open source under the MIT License, needs a client, and targets 1.20 – 26.2.
