![]() WhatsApp then stores this encrypted message on their servers until it’s delivered to the recipient. When you send a message, it gets encrypted using a specific encryption protocol (more on that next). Ideally, this means that only the original sender and the true recipient of the message can read the message in plain text. Keep in mind that, while XMPP is one of the most popular messaging protocols for chat apps, it is definitely not the only option for choosing a messaging protocol. ![]() The server then forwards this status to the original sender letting them know that the message was received by adding the “checkmark” icon next to the successfully sent message. Once a message is successfully retrieved by the client, a success status is sent back to the WhatsApp server. All the sent messages are queued on the servers until the client opens or reconnects to this socket to retrieve the messages. The XMPP on the client opens an SSL socket to the WhatsApp servers. WhatsApp uses a highly modified version of XMPP on an Ejabberd server (more on that later) to communicate with the clients. Which Messaging Protocols Does WhatsApp Use? In fact, WhatsApp only stores messages until they are received at which point they get removed. ![]() Since it would be a waste of resources to download all the messages from the cloud every time you open the app, WhatsApp chooses to store the messages locally. SQLite is a stand-alone, self-contained, relational database that is meant to be embedded into applications-which means it lives on your device. In addition to the programming language itself, another important technology that WhatsApp uses on the frontend is an SQLite database. Here's a list of all the supported platforms with the front-end language(s) that were used to build each one: They actually built a native app for each platform. With so many supported platforms, you may have guessed that WhatsApp would be a hybrid app. Up until 2017, you could even use WhatsApp on a BlackBerry. It has an iOS app, Android app, desktop app, web app, and Windows Phone app. The first part of the WhatsApp system design that a user interacts with is the mobile or web app. Let’s start with the frontend and work our way to the hardware on the backend. However, as companies do update their tech stack frequently, this information is subject to change. To the best of our knowledge, this information is accurate. Disclaimer: We scoured the internet to collect every resource on WhatsApp architecture design and have compiled and summarized it here. If you’ve ever wondered about the top dog in the chat app world, keep reading. We’ll answer all the above-mentioned questions and more. In this article, we are going to take a deep dive into WhatsApp’s architecture and system design. How does it handle so many concurrent users and messages? What kind of frameworks and programming languages enable that kind of scale? How do they keep all that data secure? So many questions! With such almost-astronomical traffic, one can’t help but wonder how WhatsApp works - its system design, server architecture, technology. According to Mark Zuckerberg, over 100 billion messages are sent over WhatsApp every day. WhatsApp is the most popular messaging service in the world.
