As video chats become more popular, many applications are trying to incorporate this feature into their products. 

WebRTC, or Web Real-Time Communication, is a free and open-source program that provides real-time communication to web browsers and mobile applications using simple application programming interfaces or APIs. It enables audio and video communication within web pages by allowing the direct peer-to-peer connection, removing the requirement for plugins or native programs to be downloaded.

WebRTC: A History

WebRTC has been around for over a decade. WebRTC is used to improve the deployment of speech and video technologies within browsers and apps. WebRTC allows developers to construct contextual apps that send and receive information to users.

Eventually, WebRTC will help replace most native apps on mobile phones and tablets as it becomes more widely used and reliable. It enables video chats, file sharing, screen sharing, and broadcasting in web applications.

Here is how it all works technically....

Integrating WebRTC

ICE, or Interactive Connectivity Establishment, is a protocol for generating media traversal candidates in WebRTC applications. It can get sent and received via NATs, or Network Address Translators, using STUN and TURN.


Session Traversal Utilities for NAT enables programs to detect the presence and types of NATs and firewalls between them and the public Internet.


Traversal Using Relays over NAT is a technology that aids WebRTC applications in traversing NAT or firewalls. Clients can send and receive data through an intermediary server using a TURN Server.

WebRTC is definitely a promising technology and can be relied upon for years to come. The technology has been spearheaded by some of the internet's most well-known names, like Google and Mozilla. WebRTC also benefits from it's light weight access by end users, there are really no strings attached since users don't needs accounts or 3rd party services to use it. Security is also a benefit of WebRTC data delivery. 

When it comes to video conferencing, video/voice services, video chat, and embeddable video tools, there are many possibilities, and it might be difficult to choose the correct supplier. Applications like Zipcan are simple to set up and have a high customization level. While it is helpful to know about the details of WebRTC, it does require a LOT of work to build a new application with WebRTC at the core. A platform like Zipcan allows you to take advantage of WebRTC with significantly less development time and long-term management.


The pandemic impacted our expectations in the virtual world. Video chat, messaging, and virtual experiences are now expected in every website or digital product. WebRTC is likely to be the underlying tech of those initiatives.
