For a Linux home lab needing virtual desktops, consider TigerVNC Xvnc. For Windows file transfer, consider TightVNC, allowing for the lack of built-in session encryption in Windows 2.8.88.

The short answer
TigerVNC has a viewer for Windows, macOS, and Linux; its server work focuses on Linux. TLS support in version 1.16.2 requires a build with GnuTLS. The server default also permits VncAuth. Debian, Ubuntu, and Fedora package TigerVNC; their versions can differ from upstream. See the versioned security details and package sources below.
TightVNC for Windows includes file transfer, which TigerVNC does not provide. TightVNC permits commercial use under the GPL at no charge. Its Windows 2.8.88 release does not encrypt session traffic. See the security limits below.

| Session encryption |
In 1.16.2 builds with GnuTLS, the server default offers TLSVnc and VncAuth; this does not require every connection to use TLS. TLSVnc uses anonymous TLS plus VNC password authentication. X.509 modes require certificate configuration. TigerVNC 1.16.2 SecurityServer.cxx . Only the first eight password characters are significant: TigerVNC 1.16.2 vncpasswd manual . |
Windows 2.8.88 has no built-in session encryption. See the TightVNC FAQ . |

Platform trade-offs
TigerVNC’s case
The TigerVNC 1.16.2 README marks the Windows server as unmaintained. Its viewer covers Windows, macOS, and Linux, but it has no file-transfer feature. Weigh those limits alongside the security modes above; platform coverage alone does not settle the choice.
TightVNC’s case
TightVNC for Windows runs as a service and transfers files between machines. Its licensing page permits commercial use under the GPL at no charge. The trade-offs are no built-in session encryption in Windows 2.8.88 and historical Java and Linux products. See TightVNC downloads and the TightVNC Windows installation guide.
Mobile viewer limit
Neither project lists an official mobile viewer among its current downloads: TigerVNC project downloads and TightVNC downloads.
Choose by situation
TigerVNC trade-offs
- Check which computer needs the server; TigerVNC Windows server is unmaintained in 1.16.2
- TLS support requires a GnuTLS build; the 1.16.2 server default also allows VncAuth
- You need headless virtual desktops (Xvnc)
TightVNC trade-offs
- Windows 2.8.88 has no built-in session encryption
- File transfer inside the session matters
- You deploy via MSI
