UltraVNC is a free, open-source VNC (Virtual Network Computing) suite for Windows comprising a VNC Server, Viewer, Repeater proxy, and Single Click (SC) lightweight server. It implements the RFB protocol to view and control a remote computer's screen, keyboard, and mouse over a network or the internet.

Use cases

  • remotely control a Windows PC from another computer
  • provide remote IT support to customers without installing software
  • connect to machines behind NAT or firewalls via a repeater
  • view and manage multiple remote desktops in tabs
  • transfer files to and from a remote computer
  • set up a free self-hosted alternative to TeamViewer

When to choose

  • you need free, open-source remote desktop access for Windows machines
  • you support customers who need one-click, no-install remote connections
  • you must traverse NAT/firewalls using a repeater or reverse connections
  • you want VNC features like file transfer, chat, and MS-Logon authentication

When to avoid

  • you need cross-platform server support (UltraVNC is Windows-only)
  • you need a polished commercial-grade remote support product with session recording
  • your environment requires modern encrypted-by-default protocols like RDP or proprietary solutions out of the box
