Is Firebase a web framework?

Firebase is a platform developed by Google for creating mobile and web applications . It was originally an independent company founded in 2011. In 2014, Google acquired the platform and it is now their flagship offering for app development.

You can use firebase to skip backend programming, or even user firebase to setup a nodejs backend (functions) . The bad thing about not using a backend is security, you would need to master firebase security rules to completely protect data.

Firebase is a fully managed backend service that gives you best-in-class infrastructure for your web apps , handling everything from user authentication and server scaling, right through to crash analytics and a reliable testing environment.
