noVNC: HTML VNC Client Library and Application

Description

noVNC is both a HTML VNC client JavaScript library and an application built on top of that library. noVNC runs well in any modern browser including mobile browsers (iOS and Android). We have a wiki with lots of helpful information. noVNC has a sister project websockify that provides a simple such proxy.

News/help/contact

The project website is found at novnc.com. Notable commits, announcements and news are posted to @noVNC.

Browser Requirements

noVNC uses many modern web technologies so a formal requirement list is not available. However these are the minimum versions we are currently aware of:

• Chrome 49, Firefox 44, Safari 10, Opera 36, IE 11, Edge 12

Server Requirements

noVNC follows the standard VNC protocol, but unlike other VNC clients it does require WebSockets support. Many servers include support (e.g. x11vnc/libvncserver, QEMU, and MobileVNC), but for the others you need to use a WebSockets to TCP socket proxy. noVNC has a sister project websockify that provides a simple such proxy.

Quick Start

• Use the launch script to automatically download and start websockify, which includes a mini-webserver and the WebSockets proxy. The --vnc option is used to specify the location of a running VNC server:

  ./utils/launch.sh --vnc localhost:5901

• Point your browser to the cut-and-paste URL that is output by the launch script. Hit the Connect button, enter a password if the VNC server has one configured, and enjoy!

Integration and Deployment
