I don't really feel the need for a curl replacement. In the past I've used httpie which is pretty slick but I end up falling back to writing tests in python using requests library.
Maybe I'm not the target audience here, but I should still say something nice I guess. It's nice that it's written in Rust, and open source tooling is in need of fresh projects ever since everyone started bunkering up against the AI monolith scraping all their work. We should celebrate this kind of project, I just wish I had a use for it.
