We used Flamelink for creating our app "Movin". It was really good experience! I like every feature of this platform. The best part about it is its amazing team! They are always there to help you whenever you need them. Nothing much from me to say here. Just go for it. Everything is fine with us after using Flamelink. We started building Movin in one month and we released it publicly in 3 months. I like that it's integrated with firebase so you don't have to worry about setting up or integrating any other services. It also makes editing your posts super simple! The only thing i dislike about this service is how expensive it can be. You pay per month whether you're using it or not. If you are just looking for an editor, and want something very basic then this could work well for you. We use this as our main way to edit articles written in markdown format (i.e., GitHub Pages).
