I’ve been working on some Wolfram Cloud deployments where we expose APIs for data processing and model serving.

While Postman has been the standard tool for testing, it’s starting to feel a bit bulky for rapid iteration, especially when dealing with dynamic endpoints and large JSON payloads.

I've come across mentions of Bruno and other lighter alternatives, but I’m curious:

What API testing tools are people here using for fast, reliable API interaction with Wolfram Cloud endpoints?

Ideally something lightweight but still supporting collections, authentication, and automated testing?

Any recommendations would be greatly appreciated.
