Dicebear Avatars vs ItsThisForThat

DiceBear is a free, open-source avatar library exposing a keyless HTTP API: request https://api.dicebear.com/{version}/{style}/{format}?seed=... and get back a deterministic avatar built from 35+ styles, from pixel-art robots to human illustrations. The same seed always renders the same image, making it a natural default profile picture for users who haven't uploaded a photo, and the whole engine — plus JS, PHP, Python, Rust, Go, and Dart libraries — can be self-hosted for private or commercial use.

ItsThisForThat is a single-endpoint novelty generator that mashes two random tech buzzwords into a startup-style "X for Y" pitch (e.g. "Google Analytics for Pandas"), served from a PHP script that's been running unchanged since at least 2018. The same api.php endpoint supports three output modes via query string — ?json for JSON, ?call=name for a JSONP callback, and ?text for a plain sentence — with no key, signup, or documented rate limit. There's no CORS header on any response, so browser code needs a same-origin proxy even though the endpoint itself is fully public.
