Types & Unique Selling Points of Video Chat Apps
Before we move on to explain how to make a video chat app from both the business and technical points of view, let’s first identify the main solution types.
This can help you understand the differences between options and clarify your intentions for a similar project.
There are three main types of video calling application, including apps for video conferencing, communication, and entertainment.
Let’s discover each video chat app type.
Conference Video Call Apps
Video conference call apps improve collaboration and speed up the process of communication between colleagues, especially when it’s needed to support people in different locations.
These video conferencing services allow users to have around 500 participants at the same time. The main requirement for building this kind of solution is high-quality video and audio calling, and the adjustment based on the speed of the internet connection.
Examples: Zoom, Google Hangouts, Google Duo, Skype, Microsoft Teams, Google Meet
Video Calling Apps
This type of apps for video conferencing allows for face-to-face video calling in everyday life. These solutions for video calling have limited capabilities. In most cases, you cannot use these grouped video calling apps for work; therefore, they are best suited for personal communication.
For example, WhatsApp only allows for four participants, and Facebook limits the number to eight at a time.
Examples: WhatsApp, Facebook Messenger, Viber, Telegram
Video Chat Apps for Entertainment
Video chatting apps can also be used for entertainment or even online dating. You may also check out how to make a dating app that utilizes instant messaging.
A great example is Houseparty, a video calling app serving as a networking service for group video chats between friends. Users receive a notification when their friends are online and available for a group video call.
Examples: Houseparty, Discord

How Does a Video Chat App Work, Technically?
Video calling is very similar to regular phone calls. In addition to hearing the other person’s voice, you can also see them. Many video calling apps also provide some additional services, including video sharing, group video calls, etc.
From a technical point of view, WebRTC is the most popular technology used to build video chat applications.
WebRTC (Real-Time Communication) is an open-source internet protocol that allows users to arrange real-time video calls using simple APIs.
This technology is used to implement a Peer-to-Peer connection without the help of a third-party web server. At the same time, WebRTC can transmit media content.
In a nutshell, WebRTS can be used together with four APIs:
- MediaStream – this API enables chatting between clients using either a microphone or a video camera.
- RTCPeerConnection – this API is responsible for the security of video calls, as it enables audio and video data transfer with encryption support and access control.
- RTCDataChannel – this API provides a Peer-to-Peer communication network for data generalization.
- OpenTOK – this is actually not an API, but a PaaS platform and an open-source library that can be used to enable cross-platform video chats.
If you want to know more about video call app development like Google Meet, the technology described above powers this solution.
Below, you can see how video calling works with a Peer-to-Peer connection structure:
Here is how the connection between two clients is established:
- The first client sends a so-called Offer to another client via a server (PeerConnection Observer).
- The second client (Remote Peer) sends a reply to the Offer via the server as well.
- The Peer-to-Peer connection is established between the clients.
After the initial exchange of Offers, the server may then allow for further development into a video chatting app, as the data can still be transferred even with the disabled server.
The next involvement of the PeerConnection Observer is required only to properly close the connection, add new members to a group video call, and to perform actions that go beyond information exchange between two clients.
How to Make a Video Chat App: Strategy Development [Steps 1-4]
The process of video calling app development consists of 8 major steps:
- Defining the value proposition
