If you are a minimalist, and are using VS Code, try https://marketplace.visualstudio.com/items?itemName=humao.re... which is a pure text syntax to describe API requests, and execute them right from the editor window. I now have api.http text file in every API-first project I am building and I love it.
I like this one because it's easy to keep API workflows with my projects. The scripting ability here is phenomenal. However only really useful if you code in VS Code.
Jetbrains also provides a similar, albeit slightly incompatible syntax for the same thing.
In the end, I think hurl [0] is nicer, because it’s open source and it’s a cli tool (and VS code also has a syntax highlighting plugin for it), making it editor independent.
