It is easy to create APIs (with no boilerplate code). Their documentation and tooling are great as well. I find their support team very helpful, also they can be accessed via slack or any other communication channel you prefer. If your app requires authentication it's not possible with graphcool yet but hope that this will change in future releases. A good fit if you want to get started quickly without having too much restrictions set by frameworks like react native. We were building an application which required user registration process where we needed to store users' credentials securely so we used auth0. The frontend was built using React Native which didn't have out of box Auth functionality, hence creating our own custom implementation.
