**Advanced Build Report** is a powerful editor-only tool that opens Unity's `.buildreport` files and presents everything inside them in a clean, fully featured UI Toolkit window. Load Unity's native `Library/LastBuild.buildreport`, pick any report with the file picker, or drag-and-drop a `.buildreport` / ABR JSON file straight onto the window.
Explore your build across nine interactive panels — Summary, Size Breakdown (with donut chart), Build Settings, Scenes & Assets, Scripts, Plugins, Stripping Analysis, Warnings & Errors, and an actionable Recommendations engine that flags oversized textures and audio, giant scenes, unused assets, excessive shader variants and build errors — with potential byte savings shown for each finding. Search, filter, and sort any table (single-column or shift-click multi-column), export the whole report to JSON / CSV / HTML / Markdown, cache recent reports for instant recall, and switch between polished dark and light themes.
Contains **zero runtime code**: one Editor-only assembly definition, no scene or prefab pollution, no reflection into your game, nothing ships in your player build.
