 KasmVNC provides remote web-based access to a Desktop or application. While VNC is in the name, KasmVNC differs from other VNC variants such as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB specification which defines VNC, in order to support modern technologies and increase security. KasmVNC is accessed by users from any modern browser and does not support legacy VNC viewer applications. KasmVNC uses a modern YAML based configuration at the server and user level, allowing for ease of management.
