Comparisons of powerful API testing tools

A bit old school, but there's also Soap UI from Smartbear -- I know, horrible name, but you can test REST APIs as well. https://smartbear.com/product/ready-api/soapui/overview/

There's also Runscope (I used to work there) -- recently acquired by CA. https://www.runscope.com

Awesome list of testing tools, had no idea Stoplight had a test product. Crazy how much faster prism is.
