Extract brand assets (logos, colors, backdrops, brand name) from any website URL.

As an API call

Get your free API key from openbrand.sh/dashboard.

cURL

curl "https://openbrand.sh/api/extract?url=https://stripe.com" \
  -H "Authorization: Bearer your_api_key"

TypeScript

const res = await fetch(
  "https://openbrand.sh/api/extract?url=https://stripe.com",
  { headers: { Authorization: "Bearer your_api_key" } }
);
const brand = await res.json();

Python

import requests

res = requests.get(
    "https://openbrand.sh/api/extract",
    params={"url": "https://stripe.com"},
    headers={"Authorization": "Bearer your_api_key"},
)
brand = res.json()

As an agent skill

Add OpenBrand to Claude Code, Cursor, Codex, Gemini CLI, and 40+ other agents:

npx skills add ethanjyx/openbrand

Once installed, your agent automatically knows how to extract brand assets — just ask it to "extract brand assets from stripe.com".

As an npm package

No API key required. Runs as a library from your server-side code.

npm add openbrand

import { extractBrandAssets } from "openbrand";

const result = await extractBrandAssets("https://stripe.com");
if (result.ok) {
  // result.data.brand_name → "Stripe"
  // result.data.logos → LogoAsset[]
  // result.data.colors → ColorAsset[]
  // result.data.backdrop_images → BackdropAsset[]
} else {
  // result.error.code → "ACCESS_BLOCKED" | "NOT_FOUND" | "SERVER_ERROR" | ...
  // result.error.message → human-readable explanation
}

As an MCP server

Use OpenBrand as a tool in Claude Code, Cursor, or any MCP-compatible client.

1. Install the MCP server (no API key needed to install):

claude mcp add --transport stdio openbrand -- npx -y openbrand-mcp

2. Get your API key from openbrand.sh/dashboard and add it:

claude mcp add --transport stdio \
  --env OPENBRAND_API_KEY=your_api_key \
  openbrand -- npx -y openbrand-mcp

Or add to .claude/settings.json:

{
  "mcpServers": {
    "openbrand": {
      "command": "npx",
      "args": ["-y", "openbrand-mcp"],
      "env": {
        "OPENBRAND_API_KEY": "your_api_key"
      }
    }
  }
}

Then ask Claude to "extract brand assets from stripe.com" and it will use the extract_brand_assets tool automatically.

Self-hosting the web app

git clone https://github.com/ethanjyx/openbrand.git
cd openbrand
bun install
bun dev

No environment variables required. Open http://localhost:3000.

What it extracts

• Logos — favicons, apple-touch-icons, header/nav logos, inline SVGs (with dimension probing)
• Brand colors — from theme-color meta tags, manifest.json, and dominant colors from logo imagery
• Backdrop images — og:image, CSS backgrounds, hero/banner images
• Brand name — from og:site_name, application-name, logo alt text, page title
