What Is OpenBrand?

OpenBrand is an open-source brand asset extraction toolkit developed by Tight Studio. Drop in any website URL and get back structured brand data: logos in multiple formats, dominant color palettes, and backdrop images.

The project positions itself as an open-source alternative to commercial brand asset services. It ships three interfaces:

• REST API — call https://openbrand.sh/api/extract with a URL and your API key
• npm package — server-side TypeScript/Python without needing an API key
• AI agent skill — npx skills add tight-studio/openbrand for Claude Code, Cursor, Codex, Gemini CLI, and 40+ other agents

As of the main branch, the GitHub repo shows 779 stars and is MIT-licensed.

Setup Workflow

Option 1 — API call

Sign up free at openbrand.sh/dashboard for an API key.

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

Response includes brand_name, logos, colors, and backdrop_images keyed by format.

Option 2 — npm package

No API key required. Install and use from 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"
}

Option 3 — AI agent integration

Add the OpenBrand skill to any compatible agent:

npx skills add tight-studio/openbrand

After installation, the agent automatically understands how to extract brand assets — just prompt it naturally.

API Response Structure

The API returns structured JSON. For a successful extraction:

{
  "ok": true,
  "data": {
    "brand_name": "Stripe",
    "logos": [
      {
        "format": "png",
        "url": "https://openbrand.sh/logos/stripe.png",
        "width": 512,
        "height": 512
      }
    ],
    "colors": [
      {
        "hex": "#6772E5",
        "usage": "primary"
      }
    ],
    "backdrop_images": []
  }
}

Error responses include a machine-readable code field: ACCESS_BLOCKED, NOT_FOUND, SERVER_ERROR, and others for programmatic handling.

Practical Evaluation Checklist

• Extract assets from 3 different sites (e.g. Stripe, Vercel, a random blog)
• Check logo format diversity (SVG vs PNG vs ICO)
• Verify color accuracy against the target site’s CSS
• Test the npm package locally (no API key path)
• Try with an agent skill if you have Claude Code or Cursor

Security Notes

• The npm package runs extraction server-side — no API key required for local use
• API calls require a bearer token; keep it out of client-side code
• The service extracts publicly available visual assets only; no authentication-bypassing involved
• Rate limits apply to the free API tier (check dashboard for current limits)

FAQ

Q: Is there a free tier? A: Yes. The API has a free tier with an API key. The npm package requires no key at all.

Q: How does it compare to commercial brand asset services? A: OpenBrand is MIT-licensed and self-hostable. It competes with services like Brand.dev or IconHorse but targets developers who want programmatic extraction without a paid subscription.

Q: Can I self-host it? A: The core extraction logic is open source. The hosted API at openbrand.sh is the public-facing service, but the npm package gives you local control.

Q: What formats does it return? A: Logos are returned in multiple formats including PNG and SVG. The exact set varies per brand depending on what the site exposes.

Conclusion

OpenBrand fills a specific niche: you need a logo, color palette, or brand imagery for a project and do not want to manually screenshot and extract it. The three-interface design (API, npm, AI skill) covers most developer workflows cleanly. MIT license means you can build on it freely.
