🌲 Kubbe

A tiny React library that makes logos look good together — like stacking wooden blocks neatly.

The Problem

Real-world logos are messy. Some have padding, some don't. Some are dense and blocky, others are thin and airy. Put them in a row and they look chaotic.

Kubbe fixes this automatically.

Getting Started

npm install kubbe

import { KubbeStrip } from "kubbe";

function LogoStrip() {
  return (
    <KubbeStrip
      logos={["/logos/acme.svg", "/logos/globex.svg", "/logos/initech.svg"]}
    />
  );
}

That's it! Kubbe will analyze each logo and normalize them to look visually balanced.

Options

gap

Space between logos. Default is 16.

<KubbeStrip logos={logos} gap={24} />

baseSize

How big the logos should be, in pixels. Default is 48.

<KubbeStrip logos={logos} baseSize={64} />

densityAware and densityFactor

Kubbe measures the "visual weight" of each logo. Dense, solid logos get scaled down. Light, thin logos get scaled up. This is on by default.

• densityAware={false} — Turn it off
• densityFactor — How strong the effect is (0 = off, 0.5 = default, 1 = strong)

// Stronger density compensation
<KubbeStrip logos={logos} densityFactor={0.8} />

// Turn it off
<KubbeStrip logos={logos} densityAware={false} />

scaleFactor

How to handle logos with different shapes (wide vs tall). Default is 0.5.

Imagine you have two logos:

• Logo A: wide (200×100)
• Logo B: tall (100×200)

scaleFactor = 0 → Same width for all logos

• Logo A: 48×24 (short)
• Logo B: 48×96 (very tall)

scaleFactor = 1 → Same height for all logos

• Logo A: 96×48 (very wide)
• Logo B: 24×48 (narrow)

scaleFactor = 0.5 → Balanced (default)

• Neither gets too wide nor too tall
• Looks most natural

<KubbeStrip logos={logos} scaleFactor={0.5} />

alignBy

How to vertically align logos. Default is "bounds".

• "bounds" — Align by geometric center (bounding box)
• "visual-center" — Align by visual weight center (accounts for asymmetric logos)

<KubbeStrip logos={logos} alignBy="visual-center" />

cropToContent

When enabled, logos are cropped to their content bounds and returned as base64 images. This removes any whitespace/padding baked into the original image files. Default is false.

<KubbeStrip logos={logos} cropToContent />

Using the Hook

For custom layouts, use the useKubbe hook directly:

import { useKubbe } from "kubbe";

function CustomGrid() {
  const { isLoading, normalizedLogos } = useKubbe({
    logos: ["/logo1.svg", "/logo2.svg"],
  });

  if (isLoading) return <div>Loading...</div>;

  return (
    <div className="grid">
      {normalizedLogos.map((logo) => (
        <img
          key={logo.src}
          src={logo.src}
          width={logo.normalizedWidth}
          height={logo.normalizedHeight}
        />
      ))}
    </div>
  );
}

Custom Image Component

Use with Next.js Image or any custom component:

import Image from "next/image";

<KubbeStrip
  logos={logos}
  renderImage={(props) => (
    <Image
      src={props.src}
      alt={props.alt}
      width={props.width}
      height={props.height}
    />
  )}
/>;

How It Works

• Content Detection — Analyzes each logo to find its true boundaries, ignoring whitespace and padding
• Aspect Ratio Normalization — Scales logos based on their shape using the scaleFactor
• Density Compensation — Measures pixel density and adjusts size so dense logos don't overpower light ones

All processing happens client-side using canvas. No AI, fully deterministic.
