Firebase vs XMPP Protocol: Build a Realtime Chat App in 2025
Published On February 5th, 2025 Communication
When it comes to real-time chat app development, the question that always remains constant is whether XMPP is good for instant messaging or Firebase.
The battle between Firebase vs XMPP has always been a fierce one for both Android and iOS. This leaves developers at the crossroads of choices, whether to choose Firebase for building chat systems or XMPP?
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.
| Google Firebase | XMPP |
|---|---|
| Developed by Google | Developed by an open-source community – Jabber |
| No customizations available | Fully customizable codes |
| 100 real-time connections free | Unlimited connections are free due to cloud hosting |
| Quick to set up and use | Difficult setting up |
| In-built database | Open-source database |
| JSON storage data | XML 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 product which helps developers to build and manage Android and iOS mobile apps. It offers features like real-time databases like Cloud Firestore, Cloud functions and messaging services.
Google Firebase helps developers build their apps faster in a most secure way. Firebase offers instant messaging infrastructure to build a custom chat app from scratch or using Firebase Chat SDK.
Owing to its quick scalability and collaborative ability with other Google consoles, it has become the first choice for most mobile app developers.
To make the comparison between XMPP and Firebase easier and the judgment to the point, let us divide the points of comparison into 5 factors:
- Protocol
- Setup Convenience
- Performance
- Platform Flexibility
- Security
- Complete Source Code
- Lifetime Data Ownership
- Deploy on Own Server
Basics of Firebase Chat
Below are a few benefits and specifics of the Firebase chat and video call app development framework.
1. Performance
Firebase for chat apps uses WebSockets and MongoDB for real-time database management. They are powerful, facilitate high performance, and offer total control across the database.
Also, Google Firebase for instant messaging has a range of Google suite applications that can be easily integrated for cloud hosting to performance monitoring.
2. Flexibility
Google Firebase cloud messaging gives the flexibility to customize data structures and supports the integration of additional features to the app as and when needed.
Firebase Chat SDK infrastructure 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 voice and video calls for Android do 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 among Firebase and XMPP, 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.
Basics of XMPP (Extensible Messaging and Presence Protocol)
Below are a few benefits and specifics of an XMPP protocol that comes to help developers to build messaging using XMPP chat SDKs.
1. Performance
XMPP for live chat can develop high-end applications and scale applications from a few users to lakhs of users quickly.
It allows coders to give standards-based presence, indicating messaging apps that thousands of users use simultaneously for instant messaging and file-sharing.
2. Flexibility
XMPP chat enables developers to create multiple functionalities on top of XMPP.
Also, it allows for extending the instant messaging functionalities that go beyond messaging, like chat rooms, network management, content syndication, file sharing, gaming, collaboration, geolocation sharing, video calling, audio messaging, and SIP connections, among many others.
3. Protocol
XMPP Chat SDK has a set of standard protocols that works with any XMPP server. Users or developers can apply this protocol to their database to exchange messages and conversations for better collaboration. Also ensure the network security using DSL to prevent the private messages.
4. Set-up Convenience
XMPP is more convenient compared to the Google Firebase. Since the infrastructure offers extreme accessibility for the developers builds the complete chat and messaging solution.
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 prevent data interception.
Now, how do 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, let’s look up XMPP vs WebSockets instant messaging protocol comparison. We can say XMPP is more extensible and flexible with high-end security features when compared to WebSockets. In contrast, a 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
- Both offer strong and reliable options to build real-time chat apps for iOS and Android.
- XMPP has a rich feature suite and supports multimedia formats
- Both are difficult to code and more.
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)
What is Firebase In-App Messaging?
Firebase in-app messaging is a protocol that supports chat app development by sending them targeted and contextual messages directly within the app. With Firebase, you can customize your messages as banners, images, or models.
Why Use Firebase for Chat?
Firebase chat helps to manage the stable connection of the users. Also, Firebase handles secure management such as users signing in, email or password verification, social media or anonymous authentication.
Is Flutter good with Firebase for building messaging app?
Yes, Flutter with Firebase is good for building messaging apps since it supports cross-platform compatibility, real-time database, and strong authentication for the app’s security and privacy.
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.
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, when building your real time chat app, you can implement End-to-end encryption on a XMPP server using plugins and extensions like OpenPGP and OMEMO.
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.
