What Favicon Generator API is
Favicon Generator API fetches and serves a website’s favicon through one endpoint, without requiring authentication. It searches page link tags, web manifests, and common favicon locations, then ranks the available candidates by quality. Responses can be images or JSON, with images as the default. Image output supports PNG, JPG, and WebP; requests can resize an image, using 64 pixels as the default size. A request can also specify a fully qualified fallback-icon URL for cases where no favicon is found. The API is free, with no API keys, rate limits, or hidden costs. Its source code is open source and available on GitHub, and it can be self-hosted using Docker or Bun. The project describes CDN or proxy caching options, including Cloudflare, BunnyCDN, KeyCDN, Nginx, and Caddy. It is built with TypeScript, Hono, and Bun, and is listed for API, self-hosted, and web use.
