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.
If you are a noVNC developer/integrator/user (or want to be) please join the noVNC discussion group.
If you want to show appreciation for noVNC you could donate to a great non- profits such as: Compassion International, SIL, Habitat for Humanity, Electronic Frontier Foundation, Against Malaria Foundation, Nothing But Nets, etc. Please tweet @noVNC if you do.

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:
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.
novnc_proxy 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/novnc_proxy --vnc localhost:5901
If you don’t need to expose the web server to public internet, you can bind to localhost:
./utils/novnc_proxy --vnc localhost:5901 --listen localhost:6081
Point your browser to the cut-and-paste URL that is output by the
script. Hit the Connect button, enter a password if the VNC server has one
configured, and enjoy!
Running the command below will install the latest release of noVNC from Snap:
sudo snap install novnc
You can run the Snap-package installed novnc directly with, for example:
novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH
If you want to use certificate files, due to standard Snap confinement restrictions you need to have them in the /home/<user>/snap/novnc/current/ directory. If your username is jsmith an example command would be:
novnc --listen 8443 --cert ~jsmith/snap/novnc/current/self.crt --key ~jsmith/snap/novnc/current/self.key --vnc ubuntu.example.com:5901
The Snap package also has the capability to run a ‘novnc’ service which can be configured to listen on multiple ports connecting to multiple VNC servers (effectively a service runing multiple instances of novnc). Instructions (with example values):
List current services (out-of-box this will be blank):
sudo snap get novnc services
Create a new service that listens on port 6082 and connects to the VNC server running on port 5902 on localhost:
sudo snap set novnc services.n6082.listen=6082 services.n6082.vnc=localhost:5902
(Any services you define with ‘snap set’ will be automatically started) Note that the name of the service, ‘n6082’ in this example, can be anything as long as it doesn’t start with a number or contain spaces/special characters.
View the configuration of the service just created:
sudo snap get novnc services.n6082
Disable a service (note that because of a limitation in Snap it’s currently not possible to unset config variables, setting them to blank values is the way to disable a service):
sudo snap set novnc services.n6082.listen='' services.n6082.vnc=''
(Any services you set to blank with ‘snap set’ like this will be automatically stopped)
Verify that the service is disabled (blank values):
sudo snap get novnc services.n6082
