WatchMe – Watch for Changes on a Page
A couple of weeks ago I was listening to a podcast and the guest worked at this data integration company. In order to provide integration with external APIs they needed to do this in case they changed any endpoint without backwards compatibility. They would monitor the API docs for any change so they could see if something had to be updated on their side. I thought it was kind of "brute" but then I realized there's no good way of doing this today.
