It's super fast, it works great with our backend API service so that we can pull data from multiple sources without having to write custom code for each one of them separately! We are able solve many problems by just using this tool (and their support team is amazing as well). I have not encountered any issues yet but if there was something they could improve upon or fix - then i would definitely let you know about these things right away :) As an example; when integrating third party services like Google maps etc., sometimes its hard managing permissions correctly because some users don't understand how OAuth flows work properly while other times developers need access tokens which isn’t always possible due user restrictions/ policies /etc.. This solves all those concerns at once since everything happens behind-the scenes through app talk ninja sdk!
