Firebase Open Source Alternatives in 2023
The Best Firebase Open Source Alternatives

This article will explore ten of the best Firebase open source alternatives. The list includes Back4App, Parse, Kuzzle, CloudFoundry, etc.

Firebase is a leading mobile and web application development platform that Google acquired in 2014. It is ideal for startups, SMEs, and new developers to build web, Android and iOS applications.

This highly scalable platform enables the coders to create applications quickly within less budget. In this regard, Firebase offers a variety of products, including Realtime Database, Cloud Firestore, Test Lab, Cloud Messaging and much more.

However, companies want to try Firebase open-source alternatives because of some limitations associated with this program. For that reason, this article displays one of the top open-source alternatives to Firebase with all of their characteristics and pricing structures. This guide will also represent the core features and drawbacks of Firebase.

Firebase Core Features

Here are the core features of Firebase:

Free to Start Platform

Firebase is an ideal platform for startups and developers who are looking for free software to build, host and run their web and mobile applications. Indeed, the Spark plan of Firebase is entirely free to use, and you can even integrate it with a variety of Google Cloud products without paying anything.

This plan provides 10 GB hosting storage, 1 GB database storage and 5 GB cloud storage. Please read Firebase Pricing Explained to know more.
