Easy UI Toolkit Inspector

🔍 Inspect Your UI Toolkit Interfaces, Live

Debugging UI Toolkit at runtime is usually a guessing game. There's no built-in way to see what's actually happening on screen, nudge a margin or a color while the game is running, and trust it'll still be there once you stop testing — you edit blind, then hunt down the right value back in the Editor, over and over.

Easy UI Toolkit Inspector changes that. Inspect, pick, and live-edit any UI Toolkit interface while your game runs, on PC, mobile, or a standalone build on a completely different device. Every change you make is tracked and reviewable, so testing in Play Mode becomes real project work instead of guesswork you redo by hand.

♦ Change Review, Not Just Live Edit

Every edit made in Play Mode is journaled. Stop testing, and a review window proposes exactly where each change belongs (an existing USS class, a new class, or the source file), showing you the exact code before anything is written.

♦ A Full In-Game Overlay

A draggable, resizable panel with a virtualized hierarchy tree, a vector box-model gizmo, and a style/attribute editor covering 88 properties and attributes across 14 sections. Full Undo/Redo, multi-selection editing, and one-click USS export included.

♦ Remote Debugging From the Editor

Connect to a standalone build running on another device or PC straight from the Unity Editor, over a lightweight TCP/UDP protocol with one-click discovery. Same 88 properties, same picker, same Undo/Redo, from inside the Editor.

♦ Works Anywhere UI Toolkit Does

Menus, HUDs, or a fully UI Builder-driven interface. PC keyboard/mouse, mobile touch, or gamepad. Requires the Input System package, installed automatically.

♦ Built to Stay Out of Your Frame Budget

Hot paths use pooled buffers and ref/out structs instead of per-frame allocations, so profiling your UI doesn't introduce the very stutter you're trying to diagnose.
