What is Firebase? All the secrets unlocked

This article will provide an in-depth analysis of Firebase, significant pros & cons, pricing structure, and core features.

Developing robust and high-quality mobile applications is a proposition that requires a lot of dedication, but more importantly, a powerful and feature-rich development platform.

Firebase from the Google stable is one such platform that has won over developers across the globe. 

Firebase gives developers many options for creating highly functional and versatile web, Android, and iOS platform applications.

While there are several contenders in the app development space, Firebase is always conversing with the best currently available platforms. 

Read on to discover how Firebase works, gain some in-depth insight into Firebase and its capabilities.

What is Firebase and how it works?

What is Google Firebase? It is a mobile application development platform from Google with powerful features for developing, handling, and enhancing applications. Firebase is a backend platform for building web and mobile applications. (1)

Firebase is fundamentally a collection of tools developers can rely on, creating applications and expanding them based on demand.

Firebase aims to solve three main problems for developers:

  • Build an app, fast
  • Release and monitor an app with confidence
  • Engage users,

Developers relying on this platform get access to services that they would have to develop themselves, and it enables them to lay focus on delivering robust application experiences.

Some of the Google Firebase platform’s standout features include databases, authentication, push messages, analytics, file storage, and much more.

Since the services are cloud-hosted, developers can smoothly perform on-demand scaling without any hassle. Firebase is currently among the top app development platforms relied upon by developers across the globe.

Firebase History

Firebase history is quite fascinating, and as many startups has a lot of ups and downs. It originated from Envolve, a startup company established in 2011 by Andrew Lee and James Tamplin. (2, 3, 4)

The company offered an API for developers to facilitate online chat integration for websites. The founders of Envolve discovered that their chat service was being utilized for relaying non-chat messages.

Developers were relying on the platform for real-time application data syncing. Lee and Tamplin decided to differentiate the real-time architecture from the chat system, a move which led to Firebase being founded in 2011. The Firebase backend as a service platform was publicly launched in April 2012. 

The first Firebase product launched was the Realtime Database. It is an API for application data synchronization across Android, web, and iOS devices. Application developers can rely on the platform for creating collaborative real-time applications. 

The company accumulated seed funding of more than $1 million in 2012 from contributors including Greylock Partners, New Enterprise Associates, Flybridge Capital Partners, and Founder Collective. The company also raised series A funding of $5.6 million in June 2013 from Flybridge Capital Partners and Union Square Ventures. (5)

Firebase Authentication and Firebase Hosting were launched in 2014 by Firebase, establishing the company as a leading mobile backend as a service (MbaaS)

Firebase became a part of Google in October 2014, and it is now the Google BaaS platform. The technology giant then acquired Divshot, a web hosting platform that was then merged with Firebase. (6)

Firebase Advantages

Here are the top ten benefits of using Firebase.

  1. Free to start
  2. Development speed
  3. End-to-end app development platform
  4. Powered by Google
  5. Developers can focus on frontend development
  6. It’s serverless
  7. It offers machine learning capabilities
  8. Generates traffic to your apps
  9. Error monitoring
  10. Security

Want to know more? See details below:

1. Free to start

Firebase is free to start with and lets users log in with their Google account. (7)

The Spark plan is free and offers many features to help developers get started. Based on growing requirements, they can then opt for the Blaze Plan.

Getting started without any cost is definitely a good option offered by Firebase and one reason it is so popular. The Spark plan does have generous database read and write number limits.

The other advantage is that the Blaze Plan takes into consideration the original free limits.

For instance, let’s consider you will host 20GB storage on the Blaze Plan. The free limit covers 10GB, and that means Firebase will only charge you 10GB for the extra usage.

2. Development Speed

Firebase is a suitable application development option that can help developers drastically reduce the time to market for developing apps.

Usually, every developer needs access to the server and host for database and backend service creation and maintenance.

Hence having a backend developer and a frontend developer is necessary to build applications. It is true even for smaller applications where backend and frontend have to cooperate at different stages.

Having frontend and backend developers can often result in errors and issues that can cause application problems increasing development cost and complexity.

However, using Firebase lets frontend developers manage all work and reduce the time needed to reach completion. That’s all thanks to ready-to-use services for data storage, authentication, notifications, analytics, and more.

On top of that, Firebase provides multiple ready-to-use services that will avoid a developer creating boilerplate code, reinventing the wheel, and start a backend from scratch.

Frontend developers won’t have many problems integrating Firebase into their codebase, thanks to its high-quality SDKs, detailed documentation, and vibrant community.

3. All in one platform (wide number of services)

Firebase also gives developers a comprehensive list of products to aid them in the development process.

Firstly, two database options are Firestore and Firebase’s Realtime Database. Likewise, Firebase lets you perform effortless cloud media storage and enables serverless application development through integrated Cloud Functions.

Firebase covers the entire application development cycle, and the platform contains features to build, release and monitor applications. Also, as the last step of the application development cycle, it provides tools to engage users and keep them using it.

4. Powered by Google 

Firebase is powered by Google, one of the most prominent and trusted names in the world of technology.

Since its acquisition, Firebase has gone through a series of changes and developments and become the reliable platform it is today. It harnesses the power of the Google Cloud and many of Google’s services. 

Firebase is now part of the Google Cloud Platform, works in perfect harmony with other Google Cloud services, and integrates with plenty of third party services. (8, 9)

Since Firebase’s acquisition, Google is heavily investing in the platform and delivering a more robust product. 

5. Focus on frontend development 

Developers worldwide prefer Firebase as it lets them focus on creating frontend code for mobile applications.

Firebase reduces the need to develop boilerplate backend code, pushing back the development completion date for applications.

Firebase makes application development convenient and helps to keep costs low.

Using Firebase also allows developers and companies to standardize the backend environment under a single and easy to learn technology.

A backend pattern decreases the amount of training required to support it and lets frontend-focused developers perform most activities.

6. It’s serverless

Scaling up and down servers it’s not an easy task! In particular, scaling up a database cluster is challenging and optimizing the performance for huge workloads requires experienced engineers.

Firebase solves this problem and provides an entirely serverless environment.

Firebase comes with a serverless architecture that requires users to pay based on requests, and there is no requirement to manage or worry about server infrastructure.

It is different from a conventional server, which has to stay functional at all times.

Firebase users are charged only when the server is being utilized due to its serverless nature.

As a result, there are fewer concerns related to scaling due to better efficiency.

Developers get freedom from taking a hands-on approach to handling DevOps, setup, infrastructure, and capacity planning.

7. Machine Learning

Machine learning is on the edge of remodeling the information technology sector. In countless ways, it’s already started.

According to Gartner, 30% of businesses will use ML in one part of their processes. (10)

Firebase is also advantageous as it offers developers the option to rely on machine learning.

ML can be utilized by both iOS and Android developers regardless of their level of experience.

Firebase comes with an ML kit with readily-available APIs for different mobile platforms features like text identification, face detection, image labeling, barcode scanning, and more.

Developers can opt for Cloud or on-device APIs based on their application development requirements.

8. Generate traffic 

Firebase facilitates app indexing to let users reengage Google Search users by providing app links on Search. (11)

Application ranking can also be enhanced on Search once by indexing an application, which helps your app gain exposure to new users who can install it.

Developers can rely on the Android Instant App that can be utilized for accessing application content.

9. Monitor Errors 

Firebase’s Crashlytics feature is a fantastic tool to find and fix issues in a fast way. Firebase can monitor both non-fatal and fatal errors, and reports are generated based on how errors affect users’ experience. (12)

10. Backups 

Firebase ensures optimal security and availability of data with the help of regular backups. (13)

The apps are protected from any possibility of data loss by relying on the automatic backup feature of this platform.

Users of the Blaze plan can easily configure the Realtime Database for taking automatic backups. Clicking the Backups tab of Firebase Database gives one access to the auto-backup settings.

Firebase Limitations

Although it’s a fantastic platform, Firebase also has some downsides.

  1. It’s not Open-Souce
  2. Vendor Lock-In
  3. Firebase does not work in many countries
  4. Only NoSQL databases are available
  5. Slow Queries
  6. Not all services are free to start
  7. It’s not cheap and pricing is difficult to forecast
  8. Runs only on Google Cloud
  9. Dedicated Servers & Enterprise Support are not an option
  10. Does not provide GraphQL APIs
Firebase Alternative Today

Let’s explore the limitations of Firebase in more granularity below:

1. It’s not open-source

Firebase is not an open-source option for mobile application development, making it a suboptimal option for many developers.

Users are unable to modify Firebase source code due to it being closed-source. Many developers who like Firebase features end up using other platforms due to this limitation. 

Although the platform is not open-source, it’s important to emphasize that many libraries and SDKs are available on GitHub. (14

This may be the largest limitation of Firebase and prevents the community from improving the product, increasing the flexibility levels and self-hosting options for developers that cannot afford Firebase pricing.

Please refer to the article Firebase Open-Source Alternatives for options that do not work with proprietary technologies.

2.  Vendor Lock-In

Another major deterrent to using Firebase is the fact that it has vendor lock-in.

It is a significant issue that stops some developers from opting for the platform. Not having access to source code can be quite difficult for some developers.

In particular, for large apps, moving out to other vendors is not an easy task, and to make this move, the entire backend would need to be rebuilt from scratch.

3.  Firebase does not work in many countries

Firebase is a subdomain from Google, and the official website is https://firebase.google.com and blocked in many countries.

Google is blocked and can’t be reached in countries like China, along with other Google services, because China has obstructed the URIs with *.google.com and *.googleapis.com.

For a complete list of countries, please refer to the Transparency Report. (15)

4. Works only with NoSQL Databases

Both Firebase database options, Firestore and Firebase Realtime Database, offer a NoSQL structure, and there is no option to use a relational database. (16, 17)

  • Complex Queries

Another challenge users face with NoSQL database is the implementation of complex queries.

Although Firebase made significant improvements on Cloud Firestore in comparison to the RTDB, running complex queries is still a challenge for certain users.

Firebase Complex Query

The example above extracted from StackOverflow delineates the challenges faced by a user moving from Parse to Firebase. (18)

Examples of the user’s issues are related to filtering, combining filters, and combining multiple queries.

Even though there is a solution for this situation and a user can craft complex with Firebase, the implementation may not simple for a beginner using the platform. 

  • Transactions

There is an interesting thread on StackOverflow that discusses how Firebase Realtime Database handles ACID properties. (19)

Even though it will support transactions, developers will have to execute their own code, unlike a traditional relational database, causing their systems to be more complicated. (20)

Firebase ACID Properties
  • Data Migration is not easy as using a SQL database

According to the article 5 Reasons Not to Use Firebase, with Firebase, a user can’t deal quickly with data-migration similar to a simple SQL database.

Firebase uses JSON, and there are virtually no SQL features, so migrating from the database will not be as easy.

5. Slow Queries

Not all databases are ideal for all use cases, and Cloud Firestore is no exception.

Although it’s a fantastic solution to scale your apps, provide offline query support and real-time updates, it has limitations as well. (21)

Some examples are:

  • Write frequency limited to 1 per second;
  • There is no native aggregation queries;
  • Maximum API request size 10 MiB;
  • Document size limit is 1 MiB;
  • Maximum concurrent connections 1M;
  • Query flexibility;
  • Queries slow performance.

There are two great articles to read to know more about Firestore limitations. The first great post is The top 10 things to know about Firestore when choosing a database for your app and the second one Why is my Cloud Firestore query slow.

6. Not all Firebase services are free to start

Although most of the services are available under the Spark Plan, there are some exceptions to this rule. Examples are Cloud Functions and Machine Learning. (7)

Cloud Functions are only available on the Blaze Plan, and a user cannot try the service under the Spark Plan.

It’s important to emphasize a free quota for Cloud Functions, but charges will happen under the Blaze Plan as soon as the user exceeds the free limit.

The second example of service not available under the Spark Plan is Cloud Vision APIs under the Machine Learning feature. This service is only available to Blaze Plan users and charges $1.5/k APIs.

7. It’s expensive and pricing is hard to predict

Firebase is a feature-rich mobile application development platform but also an expensive one for some. It does offer a free plan, but that comes with some restrictions.

It is a reason why many developers end up settling for self-hosting applications with options like Digital Ocean, AWS, or Google Cloud.

Firebase adds value on top of a pure IaaS provider, but the convenience comes at a price. Generally speaking, self-hosting an application will be cheaper than using Firebase. (22)

So, before going for Firebase, please make sure you correctly compare the upfront costs of setting a cluster at an IaaS provider and the on-going costs (servers + additional engineering costs) of maintaining the servers versus running the application directly on Firebase. 

The other aspect that makes Firebase expensive is that it is a proprietary technology, requiring a return on the engineering investment. On the other hand, open-source technologies can use the power of community-based development and deliver more affordable solutions.

Firebase provides services in a usage-based pricing model, and it is hard to cap pricing. There are no fixed pricing plans for the platform, and keeping track of resource usage can be a hassle.

Estimating the costs of Firebase can prove to be difficult for some users, especially when the scalability requirements cannot be predicted. The pricing is complicated, and Firebase has specific pricing for every feature.

Keeping the costs under a threshold can be quite challenging with the platform, and there is no easy way to cap or put hard limits on the bill.

With that said, there are ways of setting budgets, usage alerts, and even explicitly capping the number of requests thanks to Google Cloud integration. However, they require you to go beyond Firebase and are a bit complex to set up.

To best manage your spending, you should use Firebase features optimally. Examples include optimizing your Cloud Function code for quicker runtimes and correctly deciding between RTDB and Firestore. For example, use RTDB to handle small but high-throughput data and Firestore for larger data sets or when requiring complex querying.

In the past, Firebase used to offer the Flame plan. That was a fixed price $25/month plan, but it was retired in January 2020. (23, 24)

The change in the pricing structure caused inconveniences for some users, and the movement to the Pay as you go increased the charges in some situations. To know more about this topic, please read the article Firebase Costs Increased by 7,000%!

Please note that not necessarily a usage-based structure is bad! Most IaaS providers like AWS or Azure use this principle as well.

On the positive side, it will charge you exactly the resources you consume and provide a greater level of granularity.

Please make sure you understand how the billing works before committing to this model and monitor your costs regularly to avoid unexpected charges by the end of the month.

8. Runs only on Google Cloud

Firebase is now a part of Google, and its infrastructure runs entirely on the Google Cloud. (25)

There is no option to run Firebase on other cloud providers like AWS, Azure, or Digital Ocean.

Firebase limits the level of flexibility in terms of hosting options. Firebase does not provide server-level access, and problems may arise if customizing server settings is necessary.

9. Lack of Dedicated Servers and Enterprise Contracts

Firebase users do not have the option of dedicated servers or enterprise contracts. (23)

Firebase Enterprise Contracts

Not providing dedicated servers is a significant limitation. The only way to use Firebase is over a serverless structure that offers less flexibility than a fully dedicated cluster structure.

Also, sharing resources may not deliver optimal performance due to noisy neighbors.

A serverless environment is an excellent option for apps, that workload fluctuates over time. For instance, peaks and valleys during the day or the week.

Imagine a restaurant booking app; a serverless environment will work fine for this app because it will guarantee all server resources are allocated automatically during the peak periods on Friday/Saturday night.

On the other hand, several applications’ workload will not fluctuate that much but may require tailor-made security settings or some server-level access. A serverless structure will not be adequate for this scenario, and dedicated hosting a more suitable option.

Firebase does not offer enterprise pricing plans, contracts, or assistance, which is a significant issue for many potential users. However, the Blaze plan can be considered a suitable option for the need of developers with enterprise-level needs. 

10. Does not provide GraphQL APIs

Firebase does not provide GraphQL APIs as part of the standard setup. Although there are workarounds for GraphQL implementation with Firebase, REST is still the platform’s default option.

To know more about GraphQL and Firebase, please check this question on StackOverflow. (26)

Firebase Pricing

Firebase offers a free and a usage-based plan for its users. However, there is no fixed and uniformly priced plan for users to pick up and get started. (7)

(Free Plan)
The Spark Plan of Firebase is available for free, with 10 GB hosting, SSL, multiple websites, custom domain, and several other offerings.

It has some useful features like Firebase ML, Realtime Database, Cloud Firestore, and Test Lab.

These are some of the options one can avail with the Firebase Spark Plan. 
(Pay as you go)
The Blaze Plan from Firebase is available under a pay as you go, flexible pricing model.

It comes with all Spark Plan features along with some extra ones to improve the development experience.

With this plan, users have to pay $0.026/GB for hosting and the same for every GB of storage.

Many of the Spark Plan restrictions are lifted with the Firebase Blaze plan.

The Blaze Plan calculator available on the Firebase website can be a handy tool for calculating the estimated costs. 

The Free plan has some restrictions and, for example, does not give developers access to Cloud Functions.

Blaze is the pay as you go pricing plan with segmented pricing for different feature sets, i.e., Cloud Firestore, Cloud Functions, Authentication, Hosting, Firebase ML, Realtime Database, and Storage.

  • Firebase Always Free Services

Firebase is generous with its array of Always Free services that help many developers get started with their application development projects.

This article explained Firebase, its advantages, downsides, pricing structure, core features, and best alternative platforms.

Firebase is Google’s mobile app development platform. Its advantages include an end-to-end development environment, faster time to market to create apps, and scalable infrastructure. Although it’s a fantastic product, Firebase has downsides. It’s a closed-source platform, has vendor lock-in, and only provides NoSQL databases.

Pricing wise Firebase operates under two different plans. The first one is Spark that provides a generous free tier and encompasses most of Firebase features. The paid plan is called Blaze and works under a usage-based model and charges the application based on the used workload.

Firebase divides its features into three main categories; Build, Release & Monitor, and Engage. These are all employed across various stages of an app development cycle.

There is plenty of competitors to Firebase, and the more prominent ones are Back4app, Backendless, AWS Amplify, Kinvey, and Parse.

Hopefully, this article will help you to understand Firebase better and make an informed decision to use or not this service.
