How MongoDB is better than Firebase?

Developed by Google and launched in 2017, Firebase quickly syncs data via Android, iOS, and JavaScript SDKs, allowing for expressive queries that scale with the size of the result set . Users who don’t require real-time data syncs might still benefit from the one-time reads feature.

As a default Firebase database has no security , it’s the development team’s responsibility to correctly secure the database prior to it storing real data. In Google Firebase, this is done by requiring authentication and implementing rule-based authorization for each database table.

MongoDB is a more robust document database known for high performance and best-in-class security , and has several advantages over Firebase. For example, MongoDB can be operated on-premise or in the cloud (using MongoDB Atlas, or self-managed cloud MongoDB), while Firebase is purely a cloud database service.
