I've been using Postman to do my API testing. I like it generally as it's UI is ok and it's free. However, as I've gone on using it, it's become increasingly slow - not just starting up and sending requests, but also navigating the UI. I've checked my task manager and Postman is frequently hitting close to 100% CPU.
Instead of looking into making it fast again, I'd like to try out other tools for API testing. I've overheard that there are much better options than Postman so I'm interested to find out what people recommend.
