DummyImage vs PHP-Noise

DummyImage generates placeholder images on the fly from a simple URL pattern — width, height, background/text color, and format (PNG, GIF, or JPG) are all encoded in the path — with no signup or key. A live GET against the real host returned a genuine PNG 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.
