About the Custom Chat and Messaging Application

Chat applications are the primary mode of modern communication. There are many popular options out there — WhatsApp, Messenger, and Telegram are a few examples. Social media platforms also have a chat interface built into them.

We took inspiration from these platforms when creating our very customizable version of a chat application. The chat app contains all the features needed to build a modern chat app.

We have used React Native for frontend. For the backend, we used Firebase and CometChat API.

How much time will it take to customize the chat and messaging app like WhatsApp?

The cost of developing a customizable chat and messaging app like WhatsApp and Telegram can vary depending on the specific features and functionalities required. For a basic text chat app, the development time can take around 6-12 weeks, including testing.

However, for apps that require additional features such as video chat, file sharing, or real-time location tracking, the development time can be longer. More complex features may require integration with third-party APIs or the development of custom APIs, which can increase the development time and cost. It is important to engage with a skilled and experienced development team to accurately estimate the development cost and timeline based on the specific requirements of the project.
