Favicon Generator API
What it is
Favicon Generator API fetches and serves website favicons through one endpoint without authentication. It searches link tags, web manifests, and common favicon locations, then ranks candidates by quality. Responses can return an image or JSON, with image as the default. Image requests support PNG, JPG, and WebP output and can resize the result; the default size is 64 pixels. A request may include a fully qualified fallback-icon URL when no favicon is found. The service is free for everyone, with no API keys, rate limits, or hidden costs. Its open-source code is available on GitHub, and it can be self-hosted using Docker or Bun. The repository describes CDN or proxy caching with Cloudflare, BunnyCDN, KeyCDN, Nginx, and Caddy. The project uses TypeScript, Hono, and Bun, and supports API, web, and self-hosted deployment.
