ThinVNC - Web Remote Desktop

ThinVNC is a web remote access client (browser-based, HTML5). It's an improved version of the standard VNC protocol. It covers all the same scenarios, but shows a much better performance, without the need to install a PC client or any browser plugin. Once you install ThinVNC on the PC or Laptop that acts as "server", you just need a web browser to connect. Access your desktop and files remotely (even from mobile devices) and work as if you were just in from that computer. ThinVNC is a pure web Remote Access implementation (HTML5 & AJAX based). The web client works on any HTML5-compliant browser such as Chrome, Firefox, Safari, Opera, IE, or Edge. NOTE: This project was the first version of Thinfinity VNC. Visit our website try out the most recent version of this product and check our other virtualization, WFH, and RDP solutions.
