Icon Horse vs Icons8

Icon Horse fetches the favicon for any given domain — trying the site's own icon first and falling back through a chain of alternate sources so a usable image is returned almost every time — with no signup. A live GET against the real host returned a genuine PNG carrying Access-Control-Allow-Origin: *, reconfirming both auth None and cors yes.

Icons8 lets any page embed one of its icons by simply writing an image URL — no signup, key, or client library needed — with free use requiring attribution and paid plans removing that requirement. A live GET against the real host, img.icons8.com, returned a genuine icon image while carrying Access-Control-Allow-Origin: *, resolving cors unknown -> yes and reconfirming auth None.
