In the history of the world’s messaging apps, WhatsApp is one of the most popular chat applications. The primary benefit of WhatsApp is that you can send and receive messages in a variety of file types across many devices for free.

What Is the Technical Foundation of the Whatsapp Messaging App?

WhatsApp provides real-time messaging between two or more users using the Ejabberd (XMPP) Server. The creators of WhatsApp picked Ejabberd above other options because of its strong dependability and long-term stability, especially during periods of heavy demand.

The ERLANG programming language was used to construct WhatsApp. The Ejabberd server has been reorganised and many significant adjustments have been made to ensure optimum server performance.

Erlang is ideal for rapid upgrades and bug fixes. This is how WhatsApp can swiftly transmit live updates without needing a restart.

1. Insights on WhatsApp’s Data Transfer

WhatsApp sends and receives about 50 billion messages every day. The message queue’s length is important for timely data processing. All processes linked to a node’s message queue are time stamped.

In multimedia communications, the material (audio, video, or picture) is uploaded to an HTTP server, linked to, and then sent as a thumbnail to the receiving node (receiver). The material may be viewed or deleted at the user’s discretion.

2. WhatsApp’s Protocol

XMPP is the most commonly used protocol (Extensible Messaging and Presence Protocol).

DSL enhances network security without imposing restrictions on the transmission of sensitive data.

Messages are queued on the server as they are transferred. The message has been queued for delivery and will not be sent until the recipient reconnects. When a message is successfully sent, the sender is alerted by a double check mark next to the message. When messages are delivered, they are immediately deleted from the server’s memory.

Due to this rapid erasure from server memory, WhatsApp’s resources are kept at a minimum.

Additionally, Whatsapp makes use of HTML5 WebSockets, a two-way communication method.

3. How to Register for WhatsApp

WhatsApp users may sign up by inputting their phone number. Once they have entered their phone number, the user will get an OTP that is validated by the device, which will lead them to the chat page.

4. Database Administration

Mnesia DB is responsible for database administration. Mnesia is a distributed database management system with a multi user interface that also serves as the default database for Erlang. Mnesia accelerates the completion of queries, hence increasing overall efficiency.

WhatsApp is based on the FreeBSD open-source operating system. The performance of WhatsApp has been improved by optimizing ERLANG-based apps and FreeBSD. The application makes use of YAWS, a one-of-a-kind web server, to store multimedia files.

Before you begin developing an app like WhatsApp, it’s essential to realize that WhatsApp is a service, not an application. Once an application is developed, it must retain its original functionality.


The cost of a Whatsapp Clone App Development is determined by the functionality added to the app. Consider the design and development time when estimating the cost of an app. The total cost of developing an app is the sum of the design and development charges. When an application is complete, infrastructure expenses must be considered.

The features that make a whatsapp clone app perfect are:

Let’s begin by compiling a list of desirable characteristics for your WhatsApp clone:

Management of accounts

Because the service is for both the platforms of iOS and Android, users must be able to register and log in on a variety of devices. Both features may be made to work in conjunction, for example, by using the user’s mobile phone number as a username.

Account cancellation

Some users (hopefully a very small percentage) may be dissatisfied with our service and request that their account be deleted, for example, owing to concerns about data privacy.

It would be incredible if users could back up their messages, contacts, and files and have them transferred so that they could be accessible from whatever device they logged in with.


Although this function seems basic, nothing could be farther from the truth. When you stop to analyze it, there are a plethora of little details to consider for such a straightforward concept:

  1. Text message transmission
  2. Are you looking to share audio or video files with others?
  3. What if you wanted to send your uncle a photograph of your new drill but didn’t want to exchange phone numbers? Sharing relationships may be beneficial.
  4. Would you want to show your buddy the location of your meeting? Simply inform others of your present location.
  5. Receipts for reading and verification of delivery
  6. Finally, but certainly not least, group discussions!


It is necessary that the app synchronises with the user’s phone contact list in order to avoid the user manually adding friends and contact groups. It should be possible to search for friends inside a contact list and to apply profile images to specific contacts and groups. Contacts must be able to be saved as favourites and be prohibited from sending unwanted messages inside the app.

While platform-specific notifications are essential, the following must also be designed and coded:

  1. Pop-up windows
  2. Banners
  3. Vibration and noise
  4. Tones
  5. Notifications inside the application

Individual and group interactions nearly always need unique notifications.

  1. Settings
  2. Tones of contact/group
  3. Chat options
  4. The size of the textA
  5. few sentences
  6. Keyboard shortcuts are visible on-screen
  7. Configuration of personal privacy
  8. Retrace your steps to the last time you were noticed.
  9. Receipts are required to be read.
  10. Photographs of individuals
  11. Backgrounds for Chat
  12. Variations in Status
  13. Preferences for Notification
  14. Design Obstacles
