I like how easy it was for me as an individual developer (or team member) to deploy my own applications using frontastic's API platform. It also has good support from their salesforce which makes communication very simple when you have questions about your account setup. We are currently working in building out our application but we haven't encountered any problems so far. The only thing that i dislike at this point would be if there were more options available regarding different payment gateways such as stripe etc. As of now, they don't seem to offer those additional features. But overall everything seems fine! Currently solving all kinds of issues related to payments/transactions between customers and merchants via APIs.
