What is a VNC Client?

Applies to CrossBrowserTesting SaaS, last modified on January 19, 2022

When you request a Live Test for a specific operating system and browser to test your web page, a new instance is created on our servers which can be viewed and interacted with via a remote client. Since we use a VNC (Virtual Network Communication) server to deliver this service, a VNC client is required to access the session. We offer two different in-browser VNC clients. They are convenient to use since you can just request a test session and interact with it without leaving the page. These are the current offerings:

  • WebRTC client – uses Web Real-Time Communication framework

  • HTML5 Client – uses canvas element with websockets (for performance related controls, see Performance Tips)
