LibVNCServer/LibVNCClient are cross-platform C libraries for implementing VNC server and client functionality using the RFB protocol. LibVNCServer supports WebSockets so browser-based viewers like noVNC can connect.

Use cases

embed a VNC server into my C application
implement a VNC client in C
expose a framebuffer over the network for remote viewing
connect to a VNC server from a browser via WebSockets
add remote desktop functionality to an embedded device
build a custom RFB protocol client or server

When to choose

you need VNC/RFB server or client capability in a C or C++ program
you want browser-based VNC access via WebSockets
you're targeting embedded or cross-platform environments
you need broad RFB security type and encoding support

When to avoid

you want a ready-to-use standalone VNC server application rather than a library
you need a modern remote-desktop protocol like RDP or SPICE
your project cannot accept GPL-2.0 licensing
you're working outside C/C++ without binding effort
