Is Firebase Good for Backend?

Backend as a Service (BaaS) is taking web and app development by storm. With no maintenance, great scalability, and easy frontend integration, it’s hard not to see the appeal.

Google’s Firebase is one of the top BaaS offerings. Let’s see what features it provides, how it stacks up against a custom backend, and whether you should use it for your next project!

Firebase Core Features

Firebase has a lot going for it – including a slew of managed backend products/services, multi-platform frontend SDKs, great docs, support, community, and more!

Firebase Products

Firebase products come in 3 categories – Build, Release & Monitor and Engage.

The Build category includes everything you need to build a functional backend for your app. This includes real-time databases like RTDB or FirestoreCloud Functions for running custom backend code, Authentication solution for registering users with traditional methods or OAuth, static hosting, file storage, and many more!

The Release & Monitor category is especially important to mobile app developers, coming with tools for monitoring your app’s overall performance.

Here you can find integrated Google Analytics and Performance Monitoring tools to keep track of your users and their experiences. Apart from that, Firebase will help you configure your app and roll out new features, thanks to tools such as Remote Config and App Distribution.

Lastly, products from the Engage category will help you better interact with your users. Thanks to Crashlytics and A/B Testing, your app will be more stable, while Dynamic Links and Cloud Messaging will keep your users in the loop with notifications and shareable content.

Firebase SDKs and Community

With Firebase being a tightly integrated product, its SDKs play as important of a role as the products they integrate with.

Firebase Official SDKs are available for iOS, Android, JavaScript, C++, and Unity and include easy-to-use APIs for applicable products.

Apart from that, many other tools are available, such as Firebase CLI, Firebase UI, and framework bindings for, e.g., Flutter, React, or Vue.

All these first-party tools make development much faster and easier. Add to that the in-depth documentation, introductory guides, and tons of additional resources from the Firebase community, and working with Firebase should be a blast!

Is Firebase Good for the Backend?

Before using Firebase as your backend, there are some things you need to consider.


While Firebase is very scalable and versatile, it comes at a price. The pricing model used is based on your usage (pay-as-you-go) and charges for things like bandwidth, storage, read/write operation, etc.

With that said, using, e.g., Firestore, which charges per read/write operation, for a real-time chat app might be suboptimal. The same can be true for your custom use-case, and if multiple Firebase products turn out the same, you might need to look for a different backend solution.

To be fair, Firebase is still a good option for a great many apps and usually scales gracefully. With its generous free tierand several completely free products such as Authentication, Firebase is attractive for new app developers and start-ups.


Beyond pricing, the other thing to consider is the Firebase feature set. While things like real-time database, hosting, storage, and authentication should be enough in most cases, it doesn’t always have to be this way.

While good for one-time tasks, Cloud Functions can’t replace continuously running servers or complex cloud infrastructures. You should keep current Firebase features in mind and decide whether your app can work with them.

Integration and Maintenance

Firebase, like many BaaS platforms, shines when it comes to implementation and ongoing maintenance.

With Firebase, you don’t have to worry about implementing, scaling, or maintaining the backend at all and can focus solely on the Frontend. And even there, with Firebase SDKs, integrating different backend products shouldn’t be a problem.

Firebase scales very well and very far, being able to handle millions of users. With that said, at such a large scale, you might benefit more from using the more performant or more versatile infrastructure.

Can Firebase Replace Custom Backend?

With all these pros and cons in mind, can Firebase truly replace custom backend? It depends.

For the vast majority of apps and use-cases, Firebase is an excellent choice. You can start with its free tier and don’t need to worry about maintenance or scalability. It’s great for small to medium developers as it allows them to lower initial costs while focusing on providing the best user experience.

When working on a heavy real-time app like chat, or some other highly collaborative experience, Firebase is still an option, though it might be a bit pricy.

In this case, you can still stay with Firebase and optimize your usage of its products. You can also search for completely different backend solutions, or use Firebase alongside something else to get the best of both worlds.

Always consider your budget, the required feature set, and how much maintenance you’re willing to do on your own before making a decision.

The only scenario where Firebase might not be the best pick is for highly custom use-cases or huge apps.


In summary, Firebase is a great option for your next backend. It can offer an excellent experience for many use-cases, thanks to its vast portfolio of managed services, simple SDKs, and pay-as-you-go pricing. Just be sure to manage your expenses and consider the app’s functionality beforehand.
