I feel like if you only want to make a single JSON request, a simple curl invocation with the JSON data in single quotes or in a file should be enough. And if you make many different JSON requests, you're probably much better off with one of the alternative tools. Related to the second point, I really wish more people put more time into creating tools for their testers. Shell/Ruby/Python/Perl scripts that are custom-made for the specific service they're testing and provides better UI. So that instead of a sequence of curl invocations, logins, and error-prone copy-pasting, people could just: test-my-service --user j.doe:hunter2 --api comments/create --param body="hello world"
