Favicon tools for developers

Everything EasyFaviconGenerator does for humans can also be done by code: generate favicons programmatically, analyze the favicon of any website with a free JSON API, and wire it all into your build or your AI agents.

Building blocks

Favicon generation

The generation engine is a set of dependency-free ES modules. Import it in a page or run it headless to produce the whole favicon package.

Favicon analysis and download

A JSON API that fetches a page and reports all its icons, the manifest and a list of checks. Great for CI and monitoring.

MCP and agents

Give your coding agent the ability to inspect the favicon of any website.

Change log

What changed in the API and the engine.

Principles

  • The generation never leaves the browser: no upload, no quota, no API key.
  • The checker API is a simple GET returning JSON, with CORS enabled and a fair-use rate limit.
  • Everything is plain HTTP and standard web technology: no SDK required.
