## noVNC: HTML5 VNC Client
### Description
noVNC is a HTML5 VNC client that runs well in any modern browser
including mobile browsers (iPhone/iPad and Android).
Notable commits, announcements and news are posted to
@<a href="http://www.twitter.com/noVNC">noVNC</a>
There are many companies/projects that have integrated noVNC into
their products including: [Ganeti Web Manager](http://code.osuosl.org/projects/ganeti-webmgr), [Archipel](http://archipelproject.org), [openQRM](http://www.openqrm.com/), [OpenNode](http://www.opennodecloud.com/), [OpenStack](http://www.openstack.org), [Broadway (HTML5 GDK/GTK+ backend)](http://blogs.gnome.org/alexl/2011/03/15/gtk-html-backend-update/), [OpenNebula](http://opennebula.org/), [CloudSigma](http://www.cloudsigma.com/), [Zentyal (formerly eBox)](http://www.zentyal.org/), [SlapOS](http://www.slapos.org), [Intel MeshCentral](https://meshcentral.com), [Amahi](http://amahi.org), [Brightbox](http://brightbox.com/), [Foreman](http://theforeman.org), [LibVNCServer](http://libvncserver.sourceforge.net) and [PocketVNC](http://www.pocketvnc.com/blog/?page_id=866). See [this wiki page](https://github.com/kanaka/noVNC/wiki/ProjectsCompanies-using-noVNC) for more info and links.
### Features
* Supports all modern browsers including mobile (iOS, Android)
* Supported VNC encodings: raw, copyrect, rre, hextile, tight, tightPNG
* WebSocket SSL/TLS encryption (i.e. "wss://") support
* 24-bit true color and 8 bit colour mapped
* Supports desktop resize notification/pseudo-encoding
* Local or remote cursor
* Clipboard copy/paste
* Clipping or scolling modes for large remote screens
* Easy site integration and theming (3 example themes included)

See more screenshots <a href="http://kanaka.github.com/noVNC/screenshots.html">here</a>.
### Browser Requirements
* HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS
Safari, Opera 11+, Internet Explorer 9+, etc.
* HTML5 WebSockets: For browsers that do not have builtin
WebSockets support, the project includes
<a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in
WebSocket support.
* Fast Javascript Engine: this is not strictly a requirement, but
without a fast Javascript engine, noVNC might be painfully slow.
* I maintain a more detailed browser compatibility list <a
href="https://github.com/kanaka/noVNC/wiki/Browser-support">here</a>.
### Server Requirements
Unless you are using a VNC server with support for WebSockets
connections (such as [x11vnc/libvncserver](http://libvncserver.sourceforge.net/) or
[PocketVNC](http://www.pocketvnc.com/blog/?page_id=866)),
you need to use a WebSockets to TCP socket proxy. There is
a python proxy included ('websockify').
### Quick Start
* Use the launch script to start a mini-webserver and the WebSockets
proxy (websockify). 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. Enter a password if the VNC server has one
configured. Hit the Connect button and enjoy!
