SvelteKit for sure, and any other JS framework that uses the built-in Request class (which doesn’t check the Content-Type when you call json()).
I don’t know the exact frameworks, but I consume a lot of random undocumented backend APIs (web scraper work) and 95% of the time they’re fine with JSON requests with Content-Type: text/plain.
