Shameless promotion: Hurl [1] is an Open Source cli using libcurl to run to test HTTP requests with plain text!

We use libcurl for the super reliability and top features (HTTP/3 for instance) and we've added little features like:

- requests chaining,

- capturing and passing data from a response to another request,

- response tests (JSONPath, XPath, etc...)

There is nice syntax sugar for requesting REST/SOAP/GraphQL APIs but, at the core, it's just libcurl! Using verbose option, you can grep the curl commands for instance. (I'm one of the maintainers)
