AutoLayout PRO

Why AutoLayout PRO

A drop-in replacement for Unity’s LayoutGroup + ContentSizeFitter + LayoutElement stack — with the sizing model designers actually want and the performance large UIs need.

Flexbox + CSS Grid

Row, Column, Wrap, and full Grid with template tracks, repeat(), spans, dense packing, and auto-flow. Familiar to web developers; native to Figma users.

Six sizing modes

Pixels, Hug, Fill, Percentage, AspectRatio, and Raw (intrinsic text/image). Set per axis. Resolves the way you’d expect from any modern UI framework.

Zero GC, Burst-compiled

The layout engine runs on Burst with persistent NativeArrays. Incremental rebuilds via LayoutIslands mean a leaf-node change doesn’t recompute the world.

Drop-in components

ScrollView, ListView, GridView, Carousel, Dropdown, ProgressBar — all pooled, virtualized, and aware of the layout engine.

A taste of the API

The AutoUI builder constructs UI hierarchies in code without manual GameObject setup:

using AutoLayoutPRO.Builder;

AutoUI.Create(transform)
    .Column().Padding(16).Gap(8)
    .Children(
        AutoUI.Create().Row().Gap(8).Children(
            AutoUI.Create().Text("My App", 24f),
            AutoUI.Create().WidthFill(),                 // spacer
            AutoUI.Create().Text("Settings")
        ),
        AutoUI.Create()
            .WidthFill().HeightFill()
            .Background(new Color(0.95f, 0.95f, 0.95f))
            .Text("Hello world")
    )
    .Build();

Builders are pooled — after warmup, building a 100-node UI is roughly zero allocations.
