Firebase vs Supabase: What are the differences?

Firebase: The Realtime App Platform. Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds; Supabase: The open source Firebase alternative. Supabase is currently in early-Alpha .It is an open-source Firebase alternative. It adds realtime and RESTful APIs to your PostgreSQL database without a single line of code.

Firebase and Supabase can be categorized as "Realtime Backend / API" tools.

Some of the features offered by Firebase are:

• Add the Firebase library to your app and get access to a shared data structure. Any changes made to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.
• Firebase apps can be written entirely with client-side code, update in real-time out-of-the-box, interoperate well with existing services, scale automatically, and provide strong data security.
• Data Accessibility- Data is stored as JSON in Firebase. Every piece of data has its own URL which can be used in Firebase's client libraries and as a REST endpoint. These URLs can also be entered into a browser to view the data and watch it update in real-time.

On the other hand, Supabase provides the following key features:

• Full Postgres database
• Instant RESTful API
• Realtime notifications via websockets
