The ease of use, it's simple to deploy applications with multiple devices connected at once without having too many different servers running around (it can be setup as one). It is also easy enough that I don't have any problems getting help from them if needed which makes me feel like they are committed long term users instead just people who had some success in their product line but didn’t really stick out there after moving onto something else. Nothing right now! We were looking into other options when we came across cesantamoongooseserver package manager so decided give this another try compared against others then realized its simplicity was what sold us more than anything. We used this product to build an IoT device that can be controlled from a remote location. The thing is, it runs with NodeJS so you can use any Javascript libraries to interact with your device. I like how easy it was to run this in our Raspberry Pi. It was easy to setup and we didn't have to install anything. There were no issues at all, everything worked as expected. We are now using this product to build a kiosk where people can check their balance without having to go to the branch itself.
