ThinLinc is a cross-platform remote desktop server developed by Cendio AB. The server software and the users' main desktops run on Linux, but Windows applications and desktops can be accessed using the included integration with Remote Desktop Services or Citrix XenApp, or third-party programs such as Wine, Codeweavers CrossOver, or desktop virtualization software. Clients are available for Linux, Windows, OS X, and a number of thin clients.
ThinLinc uses SSH for transport encryption and authentication, and VNC for graphics, keyboard and mouse. Access to client devices is provided through different open protocols such as PulseAudio for sound (playback and recording), NFS for file system access (using a user space NFS server), and Telnet/RFC2217 for serial port access. Access to a client side Smart Cards is provided via the PC/SC interface using a proprietary protocol.
High performance graphics
Starting with version 3.0.0, JPEG compression and decompression has been accelerated using the SIMD extensions present in modern CPUs. Given a reasonable fast server, client, and network, it is possible to play back motion graphics in full screen mode. This can be done without any client side video decoder software or specialized handling of video. These performance enhancements also means that ThinLinc works very well in conjunction with the VirtualGL software, which provides hardware accelerated OpenGL on the server side. This allows 3D applications such as Google Earth to run with good performance. For example, the National Supercomputer Centre in Sweden (NSC) is using ThinLinc to run applications in their cluster remotely.
Many universities use ThinLinc to make system administration more centralized or only to make remote access to their computer systems available for students and staff. Example: Universität Zürich, Institut für Mathematik, Danmarks Tekniske Universitet, Luleå University.
The customers are generally organizations with extensive in-house knowledge of how to set up advanced computer systems, but partners like Paradigmo  and others  resell the product as a part of a complete solution.
Open source software
ThinLinc includes many components that are Free and open-source software and Cendio AB, the developer, is a driving force in many of those projects. Notable projects that are used are TigerVNC, rdesktop, OpenSSH, and PulseAudio. Source code is provided in the same archives as the binary versions.
