The BEST Unity tool got EVEN BETTER! (and FREE!)

Odin Inspector for Unity has received a major update adding a visual designer that lets developers create custom inspectors through drag-and-drop without touching source code. Previously, customizing inspectors required adding attributes directly in code, cluttering scripts and requiring source access. The new visual designer solves this by storing inspector configurations in separate files, keeping code clean, enabling non-programmers like artists and designers to build inspectors, and providing a searchable attribute library with over 130 options. The video walks through building a weapon scriptable object inspector with image previews, progress bars, conditional field visibility, validation, tabs, and debug buttons — all in minutes. Odin also supports MonoBehaviours and custom editor windows. A free 3-month trial is available with no credit card required.
