noVNC: HTML VNC Client Library and Application


$3

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).

Many companies, projects and products have integrated noVNC including
OpenStack,
OpenNebula,
LibVNCServer, and
ThinLinc. See
the Projects and Companies wiki page
for a more complete list with additional info and links.

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

$3

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.

$3

* 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!
