Build Secure Chat App

When it comes to real-time chat app development for iOS or Android, the battle between Firebase vs XMPP has always been a fierce one. 

This leaves developers at the crossroads of choices, whether to choose XMPP to develop a feature-rich chat app or build a solid messaging app for Android using Google Firebase.

So, to help ease this difficulty, we join hands in this quest of finding the right chat application framework by giving a head-on-head comparison between the two.

No customizations availableFully customizable codes
100 real-time connections freeUnlimited connections are free due to cloud hosting
Quick to set up and useDifficult setting up
In-built databaseOpen-source database
JSON storage dataXML storage data

The above distinction can be a generic one. Hence, we will see the flexibility, requirements, functionalities, performance, and a lot more between XMPP vs Firebase in the section below:

What is Google Firebase?

Firebase is Google’s own cloud-based application development framework to build high-quality mobile apps. This framework makes use of WebSockets and MongoDB.

Plus, Firebase offers app builders an app development structure consisting of analytics, messaging, databases and crash reporting logs.

Owing to its quick scalability and collaborative ability with other Google consoles, it has become the first choice for most mobile app developers.

Editor’s Note:

Did you know that in May 2023 alone, Google’s Firebase dominated the market as the preferred framework for building over 6,030 Android apps using its SDK?

To make the comparison easier and the judgment to the point, let us divide the points of comparison into 5 factors:

  • Protocol
  •  Setup Convenience
  • Performance
  • Platform Flexibility
  • Security

Must-know Basics About Firebase!

Below are a few benefits and specifics of the Firebase chat app development framework.

1. Performance

Firebase uses WebSockets and MongoDB for real-time database management. They are powerful and facilitate high performance and offer total control across the database. 

Also, Google Firebase has a range of Google suite applications that can be easily integrated for cloud hosting to performance monitoring.

2. Flexibility

Google Firebase gives the flexibility to customize data structures and supports the integration of additional features to the app as and when needed. 

It also allows developers to test and see the results live in action before rolling out the update.

This is of great help in real-time communication instances like WhatsApp, Facebook Messenger, etc. where messaging cannot be stopped to update new features.

3. Protocol

Firebase does not have any set of protocols. The user should define the database structure and assign the messaging information. 

The advantage of the Firebase in chat app is that the user can decide what should be In and Out of the database structure.

4. Set-up Convenience

On the scale of setup convenience, Google Firebase is easy and quick to market. It requires minimal procedures to get the app up and going.

5. Security Features

Similar to XMPP, Google Firebase also offers SSL encryption and allows developers to build custom-defined concepts of security and rules that help in securing data manipulation in the NoSQL Firebase database.

Well these being said, I think it would be great if we shed some light on the glimpse of Xmpp in the XMPP vs Firebase concept too, just to get to know the technology.


What is XMPP?

XMPP (Extensible Messaging and Presence Protocol) is an open XML technology that enables real-time communication for iOS, web, or Android chat apps. 

Apart from creating chat applications, XML technology can be used to create apps for customer support, ticketing, and more. 

Further, XMPP’s security and reliability features are the best and have made it the obvious choice for building real-time chat applications like WhatsApp

Another great facet about XMPP is that it is a living standard that is constantly made better by a thriving community of developers.

Must-know Basics About XMPP!

Below are a few benefits and specifics of an XMPP protocol that comes to help developers to build XMPP chats using SDKs.

1. Performance

XMPP’s USP lies in its ability to develop high-end applications and to quickly scale applications from few users to lakhs of users. 

It allows coders to give standards-based presence indicating messaging apps that thousands of users can use simultaneously for communication and file-sharing.

2. Flexibility

XMPP enables developers to create multiple functionalities on top of XMPP. 

It also allows for extending the instant messaging functionalities that go beyond chats like chat rooms, network management, content syndication, file sharing, gaming, collaboration, geolocation sharing, video calling, audio messaging, VoIP among many others.

3. Protocol

XMPP has a set of standard protocols that works with any XMPP server.  

The user can then apply this protocol to their database to exchange the messages for easy communication. And also ensure the network security using DSL to prevent the private messages.

4. Set-up Convenience

Though XMPP stands as an open-source framework, its setup is a bit time consuming primarily because of its additional features. 

5. Security Features

XMPP can be made to behave like a separate company intranet. This feature makes it a perfect pick to build enterprise communication channels. Also, XMPP can be secured with additional security measures like TLS and SASL which prevents data interception.

Now how does Google’s Firebase and open-standard XMPP stand tall against each other?
Should you build your chat app with firebase or XMPP? Let’s discuss further.

Building a chat application using firebase iOS or Android chat application using XMPP are entirely different scenarios. We are getting to the ground-zero of that question in this write-up. This is a close inspection of Firebase and XMPP for building real time chat apps.

Now, if we look up for xmpp vs websockets instant messaging protocol comparison – we can say XMPP to be more extensible and flexible with high-end security features when compared to websockets whereas  websocket gets connected with multiple users easily using lower latency lacking in security.

Final Verdict

Well, by now we would have an idea of the prime highlights of XMPP vs Firebase, and choosing which is the best can be a difficult option as

So, it is best you make a wise decision in choosing the framework. And if you are going ahead with APIs, look for providers that offer chat SDKs with XMPP and Firebase integration.

All the best!

Frequently Asked Questions (FAQs)

Is Firebase a backend or database?

Firebase includes both backend and database. This backend-as-a-service platform includes a real-time NoSQL database popularly known as the Firebase Realtime Database. When you build a chat app using firebase, this cloud-based DB lets you store and sync data in real-time and also provides backend services like authentication, database management, chat analytics, storage, hosting and more.

Does Firebase need coding?

Yes, you need coding skills to implement Firebase services on your real time chat apps effectively. Apart from firebase implementation, you’ll need to write codes for defining the functions you want on the Firebase cloud servers.

Is XMPP end-to-end encrypted?

No, XMPP is not  end-to-end encrypted, because the XMPP server which connects the communication devices has access to plaintext. This means, any message that is transmitted through the XMPP is not ciphered. However, you can implement End-to-end encryption on a XMPP server using plugins and extensions like OpenPGP and OMEMO, when building your real time chat app. 

Is XMPP deprecated?

No, XMPP (Extensible Messaging and Presence Protocol) is not deprecated. It is still actively used as an open standard protocol to build instant messaging and online presence indicators in iOS, web and Android chat apps.
