What is Web Real-Time Communication (WebRTC)?


Communication has advanced significantly. The time when it took forever to communicate a message, let alone receive feedback, has long since passed. Real-time communication is the norm today. Several technologies are referred to here that enable instantaneous live information transfer.

There is very little to no delay in real-time communication, which is instantaneous. The World Wide Web is only one example of how widely this groundbreaking technology has been embraced. Real-Time Communication is available in the browser after you enter WebRTC.

What is Web Real-Time Communication (WebRTC)?

A real-time communication and media sharing platform called WEBRTC is accessible without plugins. It uses HTML5, Javascript, and application programming interfaces (APIs) to include data sharing, audio/video streaming, and other features without needing extra plugins.

Workers presently look for a direct, trustworthy, and consistent experience while using the conferencing frameworks given by their boss because of the interoperability of the current, rising smartphone market. By laying out a norm for media spilling across internet browsers and gadgets, WebRTC answers this need and makes it conceivable to begin meetings with just a tick instead of installing extra software.

What does WebRTC do?

  • Users can connect using WebRTC without downloading any other plugins or add-ons (such as Skype or WhatsApp)
  • Since the technology enables live browser interaction, customer service can use this functionality to deliver real-time responses to inquiries
  • In actuality, there is a tonne of services employing WebRTC as a business model, providing browser-based live communication services to people worldwide
  • WebRTC is a technology that extends beyond online conversation and can be used for screen sharing and file exchange

Which browsers support WebRTC?

Fortunately, Google and several well-known web browsers collaborate to support the WebRTC protocol.

1. Google Chrome

Since its release in 2012 as version 17 of Chrome, Google Chrome is the first browser on our list that supports WebRTC. Without specialized client programs, no browser could provide video calls before that. The sheer concept of audio and video capture capabilities and their direct playing in the browser has so been hailed by users.

2. Mozilla Firefox

Beginning with its 18th Aurora version, the WebRTC protocol is supported by Mozilla Firefox, a browser that at first required manual configuration to enable video calls.

3. Opera

The 18th edition of Opera, published in December 2013, added support for the WebRTC standard, just like the aforementioned browser. The getUserMedia API interface, which is a built-in component of WebRTC, was enabled by default in this release. The Opera web browser accessed the user’s webcam and microphone via this interface.

4. Safari

A Safari browser upgrade was made available by Apple in September 2017. In the desktop version of Safari 11, full support for WebRTC was included. The fallback mechanism in earlier versions of Safari was the WebRTC or Flash Player plugin.

5. Microsoft Edge

Microsoft Edge for Windows 10 now supports WebRTC thanks to version 15019, which was released in January 2017. The default setting for WebRTC in that build was on.


The goal of WebRTC is to make it possible to create real-time communication applications for mobile platforms, IoT (Internet of Things) devices, and browsers that are rich, high-quality, and optimized for use on the web.
