Hood.ie is a complete backend for your application. It gives you features such as user signup, sign-in, reset password, data storing and retrieval and email support. All can be implemented by writing a few lines of JavaScript.
If you are frontend developer, then Hood.ie may be the best option for you. It can also help you build hybrid mobile apps easily. It utilises Offline First and noBackend architecture that can enhance the app’s performance.
