- https://en.wikipedia.org/wiki/Remote_desktop_software - refers to a software or operating system feature that allows a personal computer's desktop environment to be run remotely on one system (usually a PC, but the concept applies equally to a server), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session (i.e., a running desktop) and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration.
- https://en.wikipedia.org/wiki/KVM_switch - with KVM being an abbreviation for "keyboard, video and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mice. Although multiple computers are connected to the KVM, typically a smaller number of computers can be controlled at any given time. Modern devices have also added the ability to share other peripherals like USB devices and audio.
- x11vnc allows one to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows.
Krfb Desktop Sharing

- https://en.wikipedia.org/wiki/Vinagre - a VNC, SSH, RDP and SPICE client for the GNOME desktop environment. It was included in GNOME 2.22. It has several features, like the ability to connect to multiple servers simultaneously and to switch between them using tabs, VNC servers browsing and bookmarking. In version 2.29 Vinagre added controlling frame compression, better scaling and color depth. Version 2.30 added improved SSH tunneling and better support for copy/paste features between client and server.

- noVNC - VNC client using HTML5 (WebSockets, Canvas) with encryption (wss://) support. There are many companies/projects that have integrated noVNC into their products including: Ganeti Web Manager, Archipel, openQRM, OpenNode, OpenStack, Broadway (HTML5 GDK/GTK+ backend), OpenNebula, CloudSigma, Zentyal (formerly Ebox), SlapOS, Intel MeshCentral, Amahi, Brightbox, Foreman, LibVNCServer, and PocketVNC.

Chicken - a VNC client for Mac OS X. A VNC client allows remote access to another computer over the network. Chicken is based on Chicken of the VNC.
- https://en.wikipedia.org/wiki/Remote_Desktop_Protocol - a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software. Clients exist for most versions of Microsoft Windows (including Windows Mobile), Linux, Unix, macOS, iOS, Android, and other operating systems. RDP servers are built into Windows operating systems; an RDP server for Unix and OS X also exists. By default, the server listens on TCP port 3389 and UDP port 3389. Microsoft currently refers to their official RDP client software as Remote Desktop Connection, formerly "Terminal Services Client". The protocol is an extension of the ITU-T T.128 application sharing protocol.
- FreeRDP - a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Enjoy the freedom of using your software wherever you want, the way you want it, in a world where interoperability can finally liberate your computing experience.
- rdesktop - an open source UNIX client for connecting to Windows Remote Desktop Services, capable of natively speaking Remote Desktop Protocol (RDP) in order to present the user's Windows desktop. rdesktop is known to work with Windows server versions ranging from NT 4 terminal server to Windows Server 2012 R2.
- https://wiki.archlinux.org/index.php/FreeNX - a GPL implementation of the NX Server and NX Client Components.
- https://en.wikipedia.org/wiki/Neatx - an open-source NX server based on NoMachine's NX technology.
- X2Go enables you to access a graphical desktop of a computer over a low bandwidth (or high bandwidth) connection. Multiple users/clients can access a single X2Go Server at the same time, with each user/client having an individual Desktop session by default - however, Desktop sharing (Remote Assistance) is possible, too (see below). For the graphical part of remote desktop sessions, X2Go uses No Machine NX3 technology under the hood.
- Linux Terminal Server Project - adds thin client support to Linux servers. LTSP is a flexible, cost effective solution that is empowering schools, businesses, and organizations all over the world to easily install and deploy thin clients.
"Most network adaptors, particularly those built into motherboards, have a network boot facility. The BIOS sends a specific DHCP request over the network, and the server runs a particular network bootloader (either Pxelinux or a version of Grub). ... LTSP starts off in the same way, but instead of loading a full system from the network-mounted drive, it sets up a very minimal system, with just the basics needed to boot the kernel, start the X display, and handle mouse and keyboard input (and usually the sound). Then it opens a desktop session using XDMCP (version 4) or ssh -x (version 5), which opens a desktop from the server on the thin client.
- ShareX - a free and open source program that lets you capture or record any area of your screen and share it with a single press of a key. It also allows uploading images, text or other types of files to over 80 supported destinations you can choose from.
