Favscan — which favicon is missing?

Favscan is a demonstration prototype that shows you what a favicon scanner would report. Paste a URL and see realistic example results — no server-side scanning is performed yet.

ⓘ Demonstration prototype. The scanner on the App page runs entirely in your browser with pre-canned example data. Server-side scanning is planned but not yet built — no real URL is fetched and no icon file is actually requested.

What it checks

Every <link rel="icon"> your page declares, with its sizes and type
apple-touch-icon declarations for iOS home-screen bookmarks
The two root fallbacks browsers request by convention — /favicon.ico and /apple-touch-icon.png
Whether each icon returns the content type and dimensions it claims

How it works

Paste any URL into the scanner — a blog, a SaaS product, anything with a public page. The tool matches your domain against pre-loaded example data.

Favscan looks up example results for that site and displays a simulation of what a real scan would find. No actual fetch is performed.

Read a compact results table showing which icons would be present, which would be wrong, and what a browser, a search result, and an iOS home screen would each end up using — all based on pre-compiled example data.
