Great effort. But here’s why I will not be buying it:
1. Source code is EVERYTHING. Especially when it comes to my clients’.
2. $2.99/mo? Really? I understand that you have a server running where my code is stored (scary), but $2.99/month is insane.
The app could have been a wrapper or a render which allows my own code-server IP to be entered and your customizations kick in. That, would have made it much more valuable than me paying for a open source project as well as to have my proprietary information stored in your server.
