Node.js has proved itself by Wabion in many projects as stable and reliable environment. Moreover, it has also showed reduced development time and flexibility towards meeting agile customer needs.
Firebase is a powerful back-end application (as a Service) from Google. Distinguished itself above all, by its solid integrated real-time technology. Data is stored directly in JSON format, which makes object-relational mapping unnecessary. Furthermore, Firebase offers large-scale user authorization and that enables highly secure web applications.
With the help of Firebase we are able to develop applications within short time, which allow hundreds of users to work collaboratively on a project.
