Omnilib
by Dooji
Omnilib is a Fabric library that provides a framework for enhanced UI elements and customization, and the mod has been deprecated by its author.
What it does
The library gives other mods a base for building richer user interface elements and for letting players and developers customize them. It is required by 1 other catalog mod, Clipboard, so that mod will not run without it. Omnilib runs on client and server, so both the server and every player need it. Files are published for Fabric only, across nine release versions 1.19.2 – 1.21.5, under the GNU General Public License v3.0 only, which makes the code open source.
The author has deprecated the project. Mods that already use Omnilib are not affected and can keep working with it, but the mod and its wiki will not receive further updates. The latest Fabric file is 0.1.4 for 1.21.5, published on 2025-03-28 on the beta channel. The mod was first published on 2024-12-07. Public source code, an issue tracker and a wiki are linked from the listing.
Fabric API is required on Fabric. Other loader setups need their own compatibility layers, which the listing does not cover, since only Fabric files are published.

Use cases
Dependent mods
Mod developers can depend on Omnilib to add interface elements without writing that layer themselves.
Existing installs
Players who already run a mod built on Omnilib can keep using it, since the deprecation does not break existing dependents.
Who it’s for: Mod developers maintaining or studying interface code on Fabric, and players running a modpack or mod that still depends on Omnilib.
