Firebase is a Backend-as-a-Service (BaaS) that is part of the Google Cloud Platform. One of the most popular services of Firebase is the Realtime Database, which uses a WebSocket to sync your data. Firebase also offers services for file storage, authentication (social media and email/password authentication), hosting, and more.
You can use Firebase mainly for real-time applications, but you can also use it as your regular database for non-real-time applications if you want to. Firebase is supported by many languages (such as JavaScript, Java, Python, and Go) and platforms such as Android, iOS, and the web.
