I think I came across this tool via Hacker News 🤔. But may be not. Anyway, it does not matter.

Why it appealed to me ?

At work, we have a shared Postman workspace, which often breaks.

Because anyone and everyone can modify it (which is some times needed) But then people click the Save button, because it is easy to 😄

and now, it is broken for others.

OK, there is a concept of fork in Postman, but then everyone has their own fork.
