Simple Steps to Build a Video Chat Application

In today’s blog discusses what it takes to develop a video chat application – insights on design, features, and tech stack included.


Step 1: Focus on Target Audience

 The style and features of the video chat application vary according to the target audience and the kind of video chat app they demand.

Make sure to invest in additional data encryption and make sure the video quality is excellent.

Your project requirements and product features should be based on the target audience needs, not your personal assumptions only.


Step 2: Focus on Product Features and Requirements List

 If you want to develop a video chat app that stands out from the crowd and offers a superior and more engaging experience compared to popular choices like Skype?


Here are some video chat app features to consider:


  • Group calling
  • End-to-end encryption or advanced security protection
  • Smart PDF annotations/presentation sharing
  • Video call preview
  • Screen/desktop sharing
  • The popular video chat apps are often paired with text messaging as well
  • Custom filters, edits, and animations
  • Allow users to watch and comment on videos together
  • Video stories
  • Live-streaming functionality
  • Instant video messaging 
  • Advanced privacy 


Step 3: Role of WebRTC

 The vast majority of video chatting apps are built with the help of WebRTC – an open-source project that powers up mobile (and desktop) apps with real-time communication capabilities through numerous APIs. The project is supported by the likes of Google, Mozilla, and Opera, which says a lot about the APIs quality.

In contrast, WebRTC-based communication offers advantages that solve these issues of infrastructure and scalability. WebRTC is capable of greatly reducing server-side load strength in establishing efficient peer-to-peer communications, which in turn yields speed and performance when engaging in communications that are heavy on bandwidth such as video and voice. WebRTC also yields a reduction in the cost of providing communication services like voice and video calls are able to rely on peer-to-peer connectivity.

These advantages make WebRTC-based solutions not only much more capable of scaling but also highly dependable from an infrastructure standpoint. For businesses utilizing these solutions, reliance on peer-to-peer ensures that the impact on service due to increased server-side stresses on bandwidth is not an issue.


Step 4: App Design

 Keep the UI simple and uncluttered.

  • Create a contact book/frequent callers list.
  • Include a minimal number of controllers onto the screen and store the rest hidden in the menus.
