oωo (owo-lib)

A general utility, GUI and config library for modding on Fabric and Quilt
 

Features include:
- owo-ui, a fully-featured declarative UI library for building dynamic, beautiful screens with blazingly fast development times
- owo-config, a built-in, customizable configuration system built on top of owo-ui. It provides many of the same features as Cloth Config while many new conveniences, like server-client config synchronization, added on top
- A fully automatic registration system that is designed to be as generic as possible. It is simple and non-verbose to use for basic registries, yet the underlying API tree is flexible and can also be used for many custom registration solutions
- Item Group extensions which allow for sub-tabs inside your mod's group as well as a host of other features like custom buttons, textures and item variant handling
- A fully-featured networking layer with fully automatic serialization, handshaking to ensure client compatibility and a built-in solution for triggering parametrized particle events in a side-agnostic manner
- Client-sided particle helpers that allow for easily composing multi-particle effects
- Rich text translations, allowing you to use Minecraft's text component format in your language files to provide styled text without any code

owo is documented in two main ways:
- There is rich, detailed JavaDoc throughout the entire codebase
- There is a wiki with in-depth explanations and tutorials for most of owo's features over at https://docs.wispforest.io/owo/features

ABOUT THIS LISTING

This page describes oωo (owo-lib) by glisco. The description and screenshots are the author's own, imported from their listing on Modrinth on 31 August 2026: https://modrinth.com/mod/owo-lib

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER

This release is built for Fabric and Quilt. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.

GAME VERSION

Built for Minecraft 26.2. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.

THIS IS A LIBRARY

On its own it adds nothing you can see. It is here because other mods require it, and installing it is usually something another mod asked you to do.

DEPENDENCIES

Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.

1. Install Fabric for the Minecraft version you play, if you have not already.

2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.

3. Put it in your mods folder:

Windows — %APPDATA%\.minecraft\mods

macOS — ~/Library/Application Support/minecraft/mods

Linux — ~/.minecraft/mods

4. Launch the game with the Fabric profile selected.

ON A SERVER

Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.

UPDATING

Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
