Video calling app development is an emerging trend in the modern world. It has enabled people to connect with each other in a more convenient and efficient way. This technology has become increasingly popular among people of all ages, especially the younger generations. As a result, many businesses have been looking to capitalize on this trend by developing their own video calling apps. 

Types of video calling apps

There are several types of video calling apps available, including:

  • Consumer Video Calling Apps: These apps are designed for personal use and allow users to make one-to-one video calls. Examples include Skype, FaceTime, and WhatsApp.
  • Business Video Calling Apps: These apps are designed specifically for businesses and offer features like screen sharing, recording, and the ability to host large meetings with hundreds of participants. Examples include Zoom, Cisco Webex, and Microsoft Teams.
  • Social Video Calling Apps: These apps are designed for social interaction and allow users to make group video calls with friends and family. Examples include Houseparty, Google Duo, and Facebook Portal.
  • Healthcare Video Calling Apps: These apps are designed for telemedicine and allow patients to have virtual consultations with healthcare providers. Examples include Teladoc, Doctor on Demand, and Amwell.
  • Virtual Event Platforms: These apps are designed for hosting virtual events and webinars. They offer features like live streaming, Q&A, and interactive polls. Examples include BlueJeans, GoToWebinar, and ON24.

However, developing such an app is not an easy task. It requires a great deal of technical knowledge and expertise in order to create a successful video calling app. Fortunately, there are software development companies out there that specialize in this area. Plavno is one such company that has been helping businesses develop their own video calling apps for years.

Tech stack to develop a video calling app

To develop a video chat app, you will need the following technological stack


  • HTML/CSS/JavaScript: For designing the user interface and implementing the basic functionalities.
  • WebRTC (Web Real-Time Communication): A technology that enables real-time communication between two browsers.
  • JavaScript frameworks such as React, Angular, or Vue.js: To build a user-friendly and responsive frontend.


  • A server-side programming language like Node.js, Python, or Ruby on Rails.
  • WebRTC signaling server: To manage the communication between the clients.
  • A database such as MongoDB, MySQL, or PostgreSQL to store user data and session information.
  • Infrastructure:
  • Cloud services such as AWS, Google Cloud, or Heroku for hosting the backend and storing the media streams.
  • CDN (Content Delivery Network) for reducing latency and improving the video quality.

Additional Tools:

  • Version control system such as Git for code management.
  • Task management tools such as Trello or Asana for project management.

Please note that the exact requirements may vary depending on the specific requirements of your video chat app. However, the above stack should provide a good starting point for building a functional video chat app.
