See any VNC server's desktop in real time. Fast VNC Viewer is a lightweight Windows remote desktop client built on a pure C VNC/RFB engine (RFC 6143) — connect to a machine, watch its screen update live, and control it with your own mouse and keyboard. WHY Most remote desktop tools are heavy, subscription-based, or need software on both ends. Fast VNC Viewer speaks standard VNC, so it works with the VNC server software you already run — Linux, Raspberry Pi, home lab, lab machines, or a friend's box. No accounts, no cloud middleman, no monthly fee. The screen stream is rendered frame by frame with dirty-rect updates, so only the pixels that actually change get redrawn. The result is a responsive, low-bandwidth viewer that feels like the real desktop. KEY CAPABILITIES ★ Real-time remote desktop — live framebuffer rendering over standard VNC (RFB 3.3/3.8) ★ Full mouse control — left and right buttons and position are forwarded to the remote machine ★ Keyboard forwarding — letters, digits, arrows, F-keys and modifier keys are translated to X11 keysyms automatically ★ Clipboard to remote — selected text can be pushed to the remote desktop with one action ★ Password-protected servers — VNC DES authentication built in ★ LAN or internet — reaches VNC servers on your network or anywhere on the internet ★ Live status bar — connection state, remote resolution and FPS at a glance ★ Remembers your last connection — host, port and password are saved locally PERFECT FOR • Managing Linux boxes, Raspberry Pis and home lab machines • Jumping into a lab or classroom computer across the room • Light remote support without installing agent software • Kiosk and appliance consoles that expose VNC • Quick check-ins on headless machines MODERN WINDOWS EXPERIENCE Built with Windows 11 design (WinUI 3) and a clean, fast interface.
