## What it is
noVNC is an HTML5 VNC client implemented as both a JavaScript library and a web application that runs in any modern browser, including mobile. It is typically paired with websockify, a proxy that bridges WebSockets to raw TCP VNC servers.

## Use cases
- access a remote desktop from a browser
- embed a VNC viewer in a web app
- provide browser-based console access to VMs
- view a remote Linux desktop on a tablet
- proxy VNC over WebSockets with websockify
- give cloud users noVNC console access to instances

## When to choose
- you need browser-based remote desktop access without installing a client
- you want to embed VNC viewing into a web application
- you need mobile browser support for VNC
- you need to bridge WebSockets to a TCP VNC server

## When to avoid
- you need high-performance native remote desktop with hardware acceleration
- you need protocols other than VNC such as RDP or SPICE
- you cannot run a WebSocket-to-TCP proxy near the VNC server
