Icons8 vs PHP-Noise

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.

PHP-Noise generates a seeded, tileable static-noise PNG background image on every request, sized and colored via query-string parameters, with no signup or key. A live GET against the real host returned a genuine PNG carrying Access-Control-Allow-Origin: *, reconfirming both auth None and cors yes.
