How does it get its popularity?

The big glimpse of this best messaging app and one of the top social media platforms is that it works across every smartphone. It is nearly free which means barring the low cost of a basic mobile data plan- unlike SMS text. WhatsApp reformed the SMS style that Skype did for international phone calls. Such reformations are necessary for the ever-changing technological environment.

WhatsApp, if compared to every year’s progress, is packed with many more features now that people from every country or region are leveraging. It remains clean, fast, and simple. Moreover, it’s the best chat app for sharing multimedia pictures, audio, and video.

Erlang:

We might not be aware of Erlang as it’s very unheard of in the times. Let’s know what it is. It is a general-purpose and concurrent languages such as Java, C#, JavaScript, Python, and many more. It is used on the server-side in WhatsApp. It contains built-in support for concurrency, distribution, automatic crash recovery. Message passing (IPC) is the core feature of Erlang.

PHP:

PHP is an open-source, free server-side scripting language, that is built for developing websites and web applications. So, this best chat app has used PHP in it.

XMPP:

XMPP protocol is majorly used by WhatsApp for the instant messaging backend. It’s having the "Extensible Messaging Presence Protocol" where the client generates a connection with the XMPP Server and keeps it open till the requirement fulfillment.

MNESIA:

WhatsApp uses the MNESIA platform to manage hundreds of millions of users. It is the multi-user distributed DBMS built in Erlang. The major advantage of using it can be held comprehensibly onto the disk and in memory. It is best to get quick requests time

FreeBSD:

FreeBSD is the well-known OS distribution that is used to power desktops, modern servers as well as embedded platforms. FreeBSD acts as an excellent performance of OS, that’s why popular applications use this. Infact, it provides better security than Linux.

Yaws:

Yaws (Yet another webserver) is the high-performant multi-threaded web server, which is written totally in the Erlang language. It is suited for dynamic web applications for content too. It performs under high concurrency as it uses a lightweight threading system that can work efficiently with any database.

Facebook Data Server:

WhatsApp runs IBM SOFTLAYER cloud, which is a well-known cloud hosting company but got shifted to Facebook's own Data Center later on.

So, this best messaging app uses all the above-mentioned technologies to come out as the best one.

How To Develop a Messaging App like WhatsApp?

Step 1: Analyze the Market need

Current market analysis is important when you give a thought to developing the best messaging app. Knowing the predictions can help you include those features which might not be currently present in the app like WhatsApp.

Step 2: Select the app module which suits your business

Requirements need to be fulfilled when you’re trying to develop an app like WhatsApp-I.e., the best messaging app. You need to start thinking about how it will work like.

This app will need a Login panel, main screen, privacy policy screen, contact section, and much more in it.

Should we choose the app module or say wireframe, which is different from the business and app functionalities?

I would suggest not making this mistake as this will bring your app to another track which will not be good for your business and this will not be beneficial too. So, select the app module very wisely.

Step 3: Choose Trending & Must-Have WhatsApp Features

While start giving a push to the development process of the WhatsApp-like app, choose the features of the app. It will save time and will work much better when you further explain to the development team or the offshore developers.

Make sure that you choose the trending features for your WhatsApp. We know these days AI/ML, and technologies such as chatbots are trending and these can help in retrieving out-of-the-box features.

Skilled developers know what cross-development technologies would be needed in building an Android app like WhatsApp. I would say here mobile app developers mostly use Flutter, Java, Swift, and React Native technologies to develop chat apps like WhatsApp.

WhatsApp from Meta instead of WhatsApp from Facebook

Do you know WhatsApp has made a big change in its footer to reflect the latest company change?

Do you know what it now displays?

“WhatsApp from Meta” rather than “WhatsApp from Facebook”.

Facebook is now known as Meta after the recent big announcement.

So, when WhatsApp meta is here, you will find no one whose mind doesn’t click.

Not only WhatsApp but apps namely, Instagram, Facebook Messenger, and other apps have started showing the company’s new Meta branding tag over both Android and iOS devices. This update came just after Facebook announced its new name as Meta and talked about the Metaverse they are going to work on. Now, if you notice, every app by Meta has started its branding on the splash screen.

Undoubtedly, WhatsApp Meta plays a major role in the global areas that are important to Meta's future growth. Currently, by putting monetization efforts on hold, Meta has its focus on the future of international, cross-platform communications. With the acquisition of WhatsApp Meta, the company is certain to reach a number of people, and Meta will surely find a way to eventually cash in.

The alternatives of WhatsApp

Telegram

Telegram Messenger has been known as the best WhatsApp competitor for a very long time now. This is known as the open-source and best messaging app and people majorly use it as the WhatsApp alternative. It is packed with similar and usual messaging features like WhatsApp.

On the other hand, the Signal Foundation is providing its very own messaging app like WhatsApp. It is the Signal Private Messenger. Signal brings out several benefits in terms of security whenever compared to WhatsApp. It provides self-destructing messages and is the best advantage one could expect from any messenger app, that provides almost similar features to WhatsApp. It also offers screen security (to prevent anyone from taking screenshots) and much more into the list. The war doesn’t end here among the Signal vs WhatsApp users.
