# VncProxy
An RFB proxy, written in go that can save and replay FBS files
* Supports all modern encodings & most useful pseudo-encodings
* Supports multiple VNC client connections & multi servers (chosen by sessionId)
* Supports being a "websockify" proxy (for web clients like NoVnc)
* Produces FBS files compatible with [tightvnc's rfb player](https://www.tightvnc.com/rfbplayer.php) (while using tight's default 3Byte color format)
* Produces FBS files compatible with tightvnc player (while using tight's default 3Byte color format)
* Can also be used as:
* A screen recorder vnc-client
* A replay server to show fbs recordings to connecting clients
