While I found the overall functionality and performance of Gato GraphQL superior to the competition, it is really the documentation and especially the support rhat stands head and shoulders above the rest.
I have been fortunate to have dealings with Leo prior to his Appsumo offering. Nothing is ever too much trouble. He took a newbie like myself from complete ignorance to being able to hold my own in a discussion to being competent in getting the best out of the product in all of my varied use cases. He has been an absolute super star. I had a rare bug instance which was fixed immediately without prompting.
I know that he has plans to extend the product to cater for even more speed, greater consistency and even more use case functionality. This is the purpose of his Appsumo offering.

I couldn't recommend him more highly. Great product and service. Thank you Leo.
