WhatsApp is the most sought after messaging application that has revolutionized the messaging app market. Several attempts have been made in vain to clone WhatsApp as a chat app, but none of them yielded the result. Despite introducing similar functionalities, no chat app has ever been able to topple WhatsApp’s supremacy as a chat app.
In order to build a chat app like whatsapp, one should have a detailed understanding of its functioning mechanism and technicalities.
How Whatsapp Messaging App is Working Technically?
WhatsApp uses Ejabberd (XMPP) server which facilitates instant message transfer between two or many users on a real-time basis. High reliability and sustainability even under peak traffic the reason why WhatsApp developers chose Ejabberd above anything else.
ERLANG is the programming language used to code WhatsApp. Code restructuring and some important changes were made to the Ejabberd server to achieve optimal server performance.
Further Erlang, Whatsapp’s programming language is agile to adapt to instant updates and hotfixes. This is what helps WhatsApp to quickly push the changes to live implementation without requiring restarts.
1. Insights on data transfer in WhatsApp
WhatsApp manages over 50 billion messages a day. The key to smooth data processing lies with the message queue length. The length of the message queue of all the processes associated with a node is monitored.
In case of multimedia messages, contents (audio, video, or image) are uploaded into a HTTP server and are linked with the content and then sent to the receiving node (receiver) in the form of a thumbnail. Based on the user’s preference the content can either be viewed or discarded.
2. Protocol used by WhatsApp
The primary protocol in use is XMPP (Extensible Messaging and Presence Protocol).DSL ensures network security and also helps in preventing private data transfer.
As and when message is sent, it is queued on the server. The message waits in the queue until the recipient reconnects to receive the message. As and when a message is delivered the sender gets notified by a double check mark near the message. After the delivery the messages are instantly deleted from the server memory.
This instant deletion from server memory helps WhatsApp keep its resources to a bare minimum.
Additionally, Whatsapp uses HTML5 WebSockets which communication technology which facilitates two-way communication.
3. Registration process of WhatsApp
Users can register for WhatsApp by entering their mobile number. On entering the number, the user will be sent a OTP which once verified by the device will initiate the user to the chat screen.
4. Database management
Mnesia DB handles the heavy-duty task of database management. Mnesia is a multiuser distributed DBMS which also happens to be the default DB of ERLANG. Mnesia helps achieve quicker request responses, thereby improving the overall efficiency.
FreeBSD is the OS upon which WhatsApp is built. Improvising on the ERLANG based applications and optimizing FreeBSD, WhatsApp is able to achieve better performance. For storing multimedia files, the app uses an exclusive web server YAWS.
Build a Whatsapp like Messaging App with MirrorFly’s In-app Chat SDKs!
Having discussed the technicalities of WhatsApp it is time to shift gears over analyzing the possibilities of creating a whatsApp alternative. There are plenty of secure messaging app in the market that appear to be perfect WhatsApp clones. The reality is many of the attempts of building WhatsApp like apps are failing because they do not follow the technical aspects.
But what if we buy a third-party API rather than building a chat infrastructure from scratch? Won’t that be successful? Without a doubt yes! And with chat API providers like MirrorFly, you can easily build a whatsapp-like chat app in the quickest time possible & with the features you need.
MirrorFly is known to be one of the #1 and leading provider of Saas & Self-hosted chat SDKs that is highly preferred by developers for its quick integration capabilities, high-end messaging features, ultra-low latencies, and high scalability.
Plus, you can build the best customizable chat solutions for Android, iOS, and web apps without compromising on the security part. MirrorFly’s self-hosted chat SDKs for mobile and web also come as an ideal choice to build white-label chat apps for a one-time license cost.
Framework & Architecture of MirrorFly
As and when a user triggers a message, the chat SDK sends a request to the Ejabbered server. In return the server checks for the availability of the recipient and if available, the delivery request is sent to the recipients SDK and then delivered. If the recipient is offline, the data is stored in the Ejabbered as message will be queued in the server.
Ejabberd, the open source Jabber server has been customized by Contus Fly to improve operational efficiency. The XMPP protocol has also been customized to speedup signing in and re-signing in sessions. To protect the app from DDOS attacks and to prevent account spoofing, this mobile chat app solution has been encrypted with HMAC.
Mnesia And MySQL
For data storing, Contus Fly makes use of both Mnesia and MySQL. While Mnesia is used to maintain user login sessions, MySQL contributes in maintaining the user details, right from account credentials to other personal data.
Chat logs are a key for instant messaging applications. In order to save chat history between several nodes, Contus Fly has deployed . This database offers a good read write speed thus helping users to retrieve chat logs as and when they need.
Amazon S3 Bucket
Multimedia messages including audio, image, video are saved in Amazon S3 bucket. Registration for the app usage can be done in multiple ways including mobile number, email, user name password and social login.
WebRTC is a source code that is used to build real-time communication (RTC) in browsers and mobile app. Contus Fly has inbuilt WebRTC that allows its users to have VOIP (voice over the internet protocol) voice/video calls in their messaging app
MirrorFly’s chat SDKs lets you defend your chat platforms from any type of third-party intrusions, attacks, spam, and unwanted content with stringent security protocols like E2E, AES-256 bit, and TLS/SSL. Furthermore, its APIs are compatible with industry-regulatory standards like HIPAA and GDPR too thus protecting user sensitive data from exposure.

Frequently Asked Questions (FAQs)
Is WhatsApp chat FREE?
WhatsApp is FREE to download from Google Play Store or App Store. It lets you send and receive unlimited messages, media, and documents using your phone’s internet connection. Therefore, you need not be concerned about the limitations on the number of text messages when chatting on the app.
Are WhatsApp Chats Secure?
Yes. WhatsApp chats are secure because of the end-to-end encryption between users’ communication. The chats, images, audios, videos, calls, files and other media or documents you share with others in Whatsapp are completely safe due to the end-to-end encryption security.
Also, Whatsapp’s programming language – Erlang offers OTP framework, Process isolation and Immutable data structures
What are the security risks of WhatsApp?
There are 3 major security and compliance issues with Whatsapp app: lack of transparency, limited capacity to analyze data at scale and absence of archiving features.
How to design a chat application like whatsapp?
1. Analyze the Whatsapp source code
2. Plan your app idea based on the source code
3. Choose the platform – iOS, Android or Web
4. Plan the user experience (UX)
5. Add the messaging features
6. Publish your app on Play Store or App Store
Is there a good alternative to WhatsApp?
Whatsapp is a popular messaging app with voice and video call features, but there are many other apps like Signal, Telegram and Wire that offer similar messaging features with end-to-end encryption, just like Whatsapp. If you’d like to build a whatsapp alternative on your own, you should consider a readily-available white-label chat solution like MirrorFly. So, you can reduce development time, customize the chat features and host the chat SDK on your own servers.
How safe is a self-hosted chat app?
A self-hosted chat app can provide robust security and privacy as it lets you take complete control of the chat infrastructure. You can implement multiple encryption layers, multi-level authentication and periodic updates to resolve potential security risks.
WhatsApp recently gave a surprise with the calling feature but many users have experienced issues with it. If a Whatsapp like app is not able to come up with a smooth calling function how are the chances for a clone to provide this feature well?
Of course, it is possible. The voice call mishaps may be due to two main reasons, protocol selection and compression selection. Protocols (ex: SIP, WEBRTC) and audio compression formats (ex: Speex, G711) are those which determine the quality of a voice call in VoIP applications. The geeks at WhatsApp could be working on these two factors to set the quality right.
Moreover, if apps like Viber and Skype are able to provide uninterrupted voice calls, why other players cannot?
So finally, the world renowned $16 billion whatsapp is made from a opensource!!!
Apart from the ‘No Ads Policy’ what makes WhatsApp so special?
Mobile number based user registration. That’s the best idea which differentiated Whatsapp from rest of the instant messaging application in the market.
There are many criticisms on the new interface change of WhatsApp? Photo and video sharing experience also seems to be a bit slow? Why is that?
For sure, the slow photo and video sharing experience is not the resultant of the new user interface design change. May be it would have created a visual disconnect for the users as they would have got more used to the old design, but it has got nothing to do with the app’s performance.
Each platform (iOS, Android, Windows) uses different compliers and so the execution time for an action will differ based on it. So, if a file share is done between two nodes, each belonging to different mobile platforms (ex: iOS and Android), there could be a bit of time taken by either one or both of the compliers to process it.
Doc & pdf files unable to share on whatsapp. Is it possible to fix on clone app?
yeah of course! Exactly for that reason we have customizable option in contus fly. Not only for files sharing, we can provide customization solutions to meet your demands!
All along I was not aware of the technical functionality of whatsapp. Thankfully after reading this blog I have got a clear idea about this chat application.
An interesting article about creating chat app. Technically the points which describes protocol & registration process management are absolutely made a clear pixel on security. Worth Reading!!!
Surfed many blogs to know about Whatsapp technical features but did not get a clear note.After reading this blog, now had a clear perspective about the working functionality of whatsapp.u ‘ve explained clearly about Whatsapp API, protocol, DBMS.Very useful..Thank you
why whatsapp used ejabbered as a specific opensource? when other messenger apps like line, wechat develop their own?
ejabbered is the most robust server and is capable of handling multiplethreads, single chat, group chat, media, attachments sharings and so on. Group chats can be done as well as single message can be broadcast across multiple contacts. Ultimately, its reliability to manage mobile network’s disconnection, message deliveries, consistent conversation on any online device makes it a sturdy choice.
The tendency for software companies to develop competitive chat application like whats app is high. Your ideas were nice , hope there will be more features than whats app. It will be useful if have provided any demo link.
How WhatsApp style apps created by contus fly can stand out in clutter?
Basically it follows whatsapp’s technicalities, elegant & simple UI, easy customization along with a instant support. So there is nothing to worry. Any part of it can be customized quite easily.
Glad to see you guys are using the same architecture as Whatsapp, which can make you standout from other under-performing chat apps. Good move contus!.
Is it possible to develop an instant messaging app as a hybrid one and still expect the performance level of whatsapp?
A very exhaustive post and worth reading. But what will be the time duration taken to create whatsapp clone?
Great post! I finally understood the working of WhatsApp, but I have a slightly different need and wuld like to know how Contus could help me with that.
I have a query desk and we wanted to provide users with the feature of sending us queries via WhatsApp too, but will I be able to redirect messages coming from customers to different employees for simltaneous resolution, using Contus?
We are glad that you like the post. And to answer your question we need a bit more technical clarity. We have escalated your requirement to our technical team and one of our experts will be in touch with your shortly. You can directly contact us @ firstname.lastname@example.org
how to conite the online bulk sms to whatsapp need help send details in the my mail
Whatsapp is a social messaging app and its specialty is being cost free and ad-free. Whatsapp doesn’t support SMS campaigns and so it cannot be used to send bulk SMS for any commercial purposes. The only way to do it is to make use of the ‘Broadcast’ feature which will allow you to send messages to all your WhatsApp contacts at one go.
Unlike the group chats or messages, the recipients will not be aware of the others to whom the messages have been sent.
Ramanathan I have a whatsapp-like app I want to design and I need a programmer who makes use of erlang.
i liked the post, but how much does it costs to create a messaging app
Hai Ram, I have a doubt on Whatsup functionality…I Tried to use a same number for whatsup in two different mobiles,while adding same number on second mobile first one is automatically getting logout.how this happening..How wahtsup server validating the mobile number and devices.
Well, I’d like to mention that certain technicalities of Whatsapp are not transparent. Validating mobile numbers in different mobile devices is something which the techies at whatsapp haven’t revealed yet.
Thanks for useful information …but can you tell me the procedure to get my whats up data lost from my phone
Hey buddy, your data once lost, either by deleting it manually or losing it while uninstalling and re installing whatsapp cannot be recovered.
Data lost while uninstalling Whatsapp can be recovered using the ‘Recover’ option which prompts you to recover the previously held while reinstalling Whatsapp.
Is it possible to have in a chat application, the option of getting notifications on the persons who have seen a chat message in a group like it is in Google Hangouts?
Yes. Actually it is one of the prominent features in chat applications that complement group discussions. Each user will have an ID and once a message has been sent in a group chat, a single tick will be displayed indicating that is has reached the server.
A double tick appears when it is sent to the particular user’s mobile device and when seen by the user, the double tick turns blue. It is more similar to that of whatsapp’s message acknowledgement system.
Hi Ramanathan, I need your help with a project I’m working on with similar features. I sent an email to email@example.com. Hope we can connect soon. thanks
Sure. Thanks for writing to us. We’ll inform our experts to get in touch with you soon.

Here the facts about creating a clone app like whatsapp sounds interesting and I thoroughly enjoyed the post and its worth read!
hi ! i want to know whats app used Local notification or Push notification in iPhone app ?
Normally local notification is used and push notification will be sent to user when they are in offline.
very interesting blog and very intuitive information. thanks much.
re: The app on the mobile device requests for a unique key from WhatsApp. This ditches out the dependency of WhatsApp being used on the device.
If a unique number is generated from whatsapp server and sent to the device, where does this unique number store on the device? will it not be deleted once the app is uninstalled? The reason i asked this because, on whatsapp initial registration, the “resend sms” button was disabled for 2 hours. I deleted the app and reinstalled it. Even after that, it was disabled for 2 hours.
How does whatsapp recognizes each device as unique?(i read that, earlier it used to mobile number+ IMEI code as username/pwd). But this is changed i guess as per your statement.
can you throw some inputs on this. thank you.
Thank You So Much!

Hi Ramanathan, We know that WhatsApp is a modern day mailing system, with phone number / OTP and an encrypted code acting as the recipient mail id. What happens if I uninstall WhatsApp and install and register again with
1. Original number …. Can I see / get back all my old messages / conversations?
2. Install with a different (known / friend’s) number.
If the friend’s number also uninstalls WhatsApp, will there be a clash? CAn I get to see friend’s old conversations / messages?
Yes, you can get back your messages but before you need to sync your WhatsApp account with your Gmail id that your conversation and media will be stored on google drive. And If you want to you back up your friends WhatsApp conversation you need to know his/her Gmail account Id and password and add it on your mobile phone and sync it with WhatsApp. And you will be able to recover the conversation if it would exist.
can u please help me in code of how to send push notifications from ejabberd server to android app when app is offline like we receive notifications in whatsapp and facebook
Hello. Of course not, because its not stored on server, as e-mail service used to do. (Use to do.). You can receive the messages, received after the registration proccess. But i think only one mobile phone number can be logged on account. There also is another permisions level for its accounts, if you activate it, need to re authenticate to use that phone number. If you reinstall, the backup database can be opened on your phone, its end to end encrypted. That means, the backup database is encripted, and key exists only on the phone that creates it. Go do something better, try to go fishing ..
I intend to use WhatsApp for my private business with a company well known to everyone and I need a private discussion with an expert like yourself. How can I do that?
could u provide the time taken of a message to travel from one phone to another. factors affecting it and how we can measure the latency?
during the backup of my chats & images the backup is not completing successfully on my drive.it shows massege like unfortunately whattsapp not responding.
Hi Ramanathan, how does one create settings similar to those on WhatsApp where one can change their account name and mobile no?
i loved your articles about How server of WhatsApp works , even I have posted one blog on the same: techgigi.com/how-whatsapp-server-works/ . hope you will also like my info too…
you are my inspiration, keep about keep updating your blogs ….

Hi: do you know if group data (name of the group and members) are stored in the whatsapp servers? Or are also a app-side?
I didnt understand your business model, I have few questions:
1. Is it like this, we give a requirement, you make the modification for the clone, and host it, we pay monthly?
2. Will you provide the source code?
3. Who will manage the security issues like hacking threats?
4. Can we brand it in our name? Can we host the app in platforms like PlayStore in our name?
Sorry, I am new to it, so these questions.
Thanks in advance.
1) It is a one-time payment.
2) If you want to develop the chat app for your business, We will provide full access to source code.
3) After the development, we provide the technical support as long as you need!
4) Yeah, It’s Whitelabel Solution.
Why Erlang was chosen for WatsApp?? If instead at server side the implementation was in C++ then how will you rate the performance and hardware usage/requirements for Erlang vs C++ ??
What Is price for white label chat app like whatsapp
Its Really amazing article for people like us. I’ve a doubt , can we clone the whats app with different configurations like language will be Java , server will be Apache Tomcat or Jboss ? Because you defined each and every technologies for improving the performance of whats app so changing the technologies will give impact on the application ?
What will be the market cost for developing a whatsapp clone?
Hi McKinley. Thanks for writing to us.
Obviously the answer will be unanimously the same “It depends upon your requirements”. Tell us your requirements and we can help you in knowing the cost.
Hi, guys please let me know, Is it possible to target the multiple countries with their actual time in Whatsapp?

Hi Ramanthan, i have one doubt.. if whatspp is not storing text messages in their server after it is sent..then how the cyber cell monitors the unwanted messages in whatsapp??
Can u pls explain it technically.?
Hey man, sorry that we cannot answer your question technically as it is completely up to the cyber cell. Whatsapp stores the backup of data sent, be it text message or any multimedia content, only till the time recipient accesses it. Once it is done or when you get a double tick, all the data will be deleted from Whatsapp’s server.
Please I need someone who can develop a whatsapp-like app. If u can get me someone who is good with erlang I will be happy, thank you.
