I built milkman[1], an alternative to postman because I wanted one tool to integrate with the whole web development stack. One tool that contains my SQL, rest and grpc calls to easily debug issues. Also nearly none of those kind of tools that existed supported SSE which I also use in my day to day work.

Edit: I love these threads. You read so many things and Frameworks and random stuff that you really learn in what silo you are actually living
