ItsThisForThat vs JSONPlaceholder

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.

JSONPlaceholder is one of the longest-running free fake REST APIs, serving a fixed set of 100 posts, 500 comments, 10 users, 100 albums, 5,000 photos, and 200 todos as JSON. Every standard verb works against each resource, including nested routes like /posts/1/comments, though POST/PUT/PATCH/DELETE only simulate a write and return a fake response without persisting any change. Its data and IDs never change, which is exactly why it's the default backend in countless framework tutorials and testing guides.
