Quick Build Size Reporter

Stop guessing what's making your build big.

Quick Build Size Reporter hooks Unity's build pipeline and, after every build, prints a clean, colored report of exactly where your size went — straight to the Console, saved as a .txt, and shown in a dark editor window.

What you get after every build

Per-category breakdown: Textures, Meshes, Audio, Shaders, Fonts, Animations, Materials, Prefabs, Scripts, Data, Plugins, Other — with proportion bars and percentages.

Largest-files list: the top N heaviest assets with color-coded severity markers. Click one in the window to ping it in your Project.

Build-over-build delta: every build is compared to the last, so a size regression is obvious before it ships.

Warnings: counts of oversized files and large uncompressed textures, plus a third-party / Packages total.

Colored & readable: rich-text colors and severity dots that render right in the Unity Console.

Editor window: Tools > Quick Build Size Reporter — Latest / History / Settings, with CSV export.

Saved reports: a timestamped .txt per build in your project's BuildReports/ folder.

Zero setup, zero risk

Import it and build — that's the whole setup. It is Editor-only: nothing ships in your game, there is no runtime cost, and the entire pass is guarded so it can never fail a build.
