JSON-Menu is a mac app that runs in the menu bar and lets you visualize data a JSON endpoint.
It's awesome!!! Looks great and its more usable than hot chochito menú.
Easy to implement
I just installed it and it requires API and there is nothing in the website to mention that. I just tried random text and it worked fine with the json file provided.
Nice idea, helpful presentation and easy to integrate with services
needs more documentation
