I'm quite surprised of what Postman and Insomnia did. They barely have any moat, they basically sell GUI and API for cURL.

I had been using Postman and got annoyed it, so I developed my own API exploration and testing tool for my use case. I also saw recently that there is a YC-backed Postman competitor, let alone a dozen of other open source alternatives.

What did insomnia do? I’m a bit out of the loop on this one

Try NativeRest, if you use Windows
