TightVNC is a lightweight remote desktop application focused on performance with file transfer capabilities, making it suitable for Windows and Linux users. In contrast, KRDC offers better cross-platform support and built-in encryption, making it more secure and user-friendly, but it lacks some advanced features like file transfer and multi-session support.
