httparty is a dsl wrapper around net/http, so it's also limited by it. For instance, it doesn't come with keep-alive support (I'm using httparty in my dayjob legacy code).

httpx is more than concurrent connections. It's actually about concurrent requests done right, advanced http features (it can do connection coalescing, alt-svc), and it comes with a baked-in plugin system which makes it easy to extend.

Go through the wiki and give it a try when you can.

Me too but I am intrrigued.
