I liked paw, but postman is free. I'd consider paw at half the price because I don't spend that much time testing REST APIs, but when I do I don't mind using a better tool than httpie or curl. Postman does the job (quite well) for free.

We do have a subscription service now called Postman Pro - does API documentation (api.getpostman.com), API Monitoring, Mock servers, Team collaboration and it has a powerful API (api.getpostman.com). More coming soon! Postman - the app will always remain free. :) (Founder here)

There's another free REST client called Insomnia (https://insomnia.rest), which I've been working on for the past two years, but I don't think there are any other popular "native" options. For some reason, all of the REST clients seem to be Chrome apps. It will be unfortunate when Google sunsets Chrome apps next year :(
