TurboVNC
What TurboVNC is
TurboVNC is free remote-display software designed for demanding 3D and video workloads. It sends framebuffer updates through the RFB protocol and works with VNC distributions that support Tight encoding. Accelerated Tight encoding plus SIMD-accelerated JPEG and zlib processing handle compression. VirtualGL integration can provide GPU-accelerated OpenGL across a complete TurboVNC session, supporting remote 3D applications over different networks. Security options include SSH and multi-level SSH tunneling, TLS encryption, and configurable authentication policies. Servers can add TOTP two-factor authentication through the OATH Toolkit PAM module. Built-in WebSockets support allows noVNC and other browser viewers to connect without a proxy. TurboVNC supports Linux, macOS, Windows, and web browsers. Official support covers RHEL and Ubuntu LTS on x86-64 and AArch64, with macOS and Windows supported for the viewer. Other environments receive community support or may require a paid support contract.
