That looks like a fantastic app to be working on. Also, a great job with the demo video explaining what it is. The only feedback I could give for now is that the "Free" plan should include some extra feature from the paid plans (e.g. User Authentication, Custom Domains, etc.) as it seems way to basic and the first paid plan is quite expensive. I may sound like a cheapskate but you'll pull in the right crowd if you tax other metrics like traffic/bandwidth/cpu/ram/etc.
