WeakAuras is a powerful and flexible framework that allows the display of highly customizable graphics on World of Warcraft’s user interface to indicate buffs, debuffs, and other relevant information. This add-on was created to be a lightweight replacement for Power Auras but has since introduced more functionalities while remaining efficient and easy to use. 

Features

1. An intuitive and powerful configuration interface
2. Custom textures including all textures from Power Auras and Blizzard’s spell alerts
3. Progress bars and textures that show the exact duration of auras
4. Displays based on auras, health, power (mana, rage, soul shards, holy power, etc.), cooldowns, combat events, runes, totems, items, and many other triggers
5. Preset and user-defined animations
6. Custom side-effects such as chat announcements or sounds
7. Grouping, which allows multiple displays to be positioned and configured at the same time
8. CPU optimizations such as conditional loading/unloading of displays, modularity, and prevention of full aura scanning
9. Powerful customization options, such as animation paths, on-show/on-hide code, and custom triggers, for Lua-savvy users
