Cuer

Why it's ranked here

Cuer has a focused, unusually composable design. The simple interface handles ordinary QR rendering, while separate root, cell, finder, and arena pieces allow substantial visual control without replacing the encoding layer.

What's good

The output inherits the current text color and defaults to full available size. Cells and finder marks expose independent radius and fill controls. Adding central content automatically reserves space and raises low error correction to medium.

Tradeoffs

This is an opinionated React renderer, not a general QR toolkit. The public entry exposes one component family, and central content uses an SVG foreign object. The supplied material shows rendering and encoding, but no scanning or decoding interface.

How to use it well

Use it in React products that need branded, responsive QR graphics with modest styling control. Start with the single component, then compose its visual parts for logos or custom geometry. Choose another tool when you need scanning, decoding, or a framework-neutral interface.
