Why Choose This Over Odin Inspector?

Odin Inspector is a great tool, but it costs $55+ per seat. AnkleBreaker Utils Inspector provides the most commonly used attributes — ShowIf, BoxGroup, TabGroup, Button, Required, ProgressBar, PreviewField, TableList, and more — completely free and open source. It covers 90% of what most Unity developers use Odin for, at zero cost.
