GUI Inspector

GUI Inspector lets you inspect the GUI elements of any Minecraft screen. You can view a tree of all widgets and components on a screen, including their class names and properties. Class and method names are properly mapped to Yarn and Mojang mappings in unobfuscated versions.

Not only can you view properties, but you may also manipulate them, including most immutable properties. You can even remove an element entirely. Note that any changes are not permanent. This mod is not intended to be a personal GUI customization mod; it is a tool for developers.

Selecting an element outlines it in-game so you can easily identify it. You can also enable Inspector Mode to click directly on an element in-game and have it highlighted in the tree.

For more detailed inspection, you can capture draw calls and inspect their properties, call stacks directly, and the texture used to render that call, if applicable.
