KATT https://github.com/for-GET/katt is the same concept, but following the pattern matching philosophy. Written in Erlang, available as a CLI tool as well but needs the erlang runtime installed.
Disclaimer: I'm one of the authors, thus biased, but the reason I'm mentioning KATT is that the low barrier of entry for captures and asserts makes it a nice requirement tool for non-techs to write complex API scenarios.
