A Scalable Real-time Backend for Your Web Application

Firebase is a cloud service that automatically synchronizes data between clients and with our cloud servers. It frees developers from worrying about how their data will be communicated and stored, and allows them to focus on their own application logic. Apps built with Firebase can be written entirely with client-side JavaScript, update in real-time out-of-the-box, are inherently scalable, and interoperate well with existing services.

Firebase is designed so developers can build great apps quickly, and it is intended for both expert developers as well as those just getting started. Firebase’s synchronization approach can provide all of the data storage and transmission needs of many apps. This does not mean, however, that developers can’t run their own servers.

Firebase plays nicely with any existing system through its REST API or its Node.js library, allowing developers of existing apps to add scalable real-time functionality with just a few lines of code.
