I started working for Ably recently, at the beginning of 2022. One of the first tasks I was given was to build a demo project that used one of the Ably SDKs. Working as a backend Go developer for the past 4 years made my choice of SDK easy. I definitely wanted to work with ably-go. I found myself wondering how to explore, debug and test an SDK in a visual way, rather like how the Postman API Client interacts with an API.
