Abyss UI

AbyssUI is a minimalist World of Warcraft interface. It changes parts of the interface so you can have a more customizable and clean UI. The goal was to have a high customizable interface that changes little of the wow artwork or functionality.

ElvUI/TukUI

ElvUI and TukUI are full user interface replacements for World of Warcraft, which means they completely replace default UI. You can customize every single part of your UI to your liking. ElvUI is a more user friendly. TukUI requires you to do more work to get everything just right.

Em's UI

Efficient addon which aims to add some quality of life features and visual improvements to the DragonFlight UI. All elements are movable/configurable through the new UI edit mode and other standard game settings.

GW2 UI

GW2 UI is based on the Guild Wars 2 UI and aims to increase immersion and efficiency. The entire UI is hand-painted, and hand-coded. Each interface element has been (or will be) rewritten, to provide enhanced functionality as well as improve the user experience.

HydraUI

A visual interface replacement for World of Warcraft. It restyles the default interface, while adding many useful features. It requires no setup, and is configurable in-game.

Yet another UI, but this one is a bit special. You can choose an Orbs or Classic bar layout style.

nUI

ViksUI

ViksUI is a fully functional UI replacement for WOW with many extra features that are not included in the standard UI. Almost everything can easily be changed in-game. Panels and borders can have colors on, or turned off.
