PuTTY
PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator. PuTTY is a client program for the SSH, Telnet, Rlogin, and SUPDUP network protocols. These protocols are all used to run a remote session on a computer, over a network. PuTTY implements the client end of that session, the end at which the session is displayed, rather than the end at which it runs. In really simple terms, you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else. All of PuTTY's settings can be saved in named session profiles. You can also change the default settings that are used for new sessions.

Alacritty
Alacritty is a modern, cross-platform terminal emulator powered by OpenGL that delivers GPU-accelerated performance with sensible defaults and extensive configuration. Rather than reimplementing functionality, it integrates seamlessly with other applications to provide a flexible feature set without sacrificing speed. Supported on BSD, Linux, macOS, and Windows, Alacritty is considered beta and still under active development, yet it already serves many users as their daily driver terminal. Key features include Vi Mode for moving around and creating selections using vi bindings; a Search function for querying text within the scrollback buffer; Regex Hints that mark patterns for mouse or keyboard interaction; and Multi-Window support to improve resource usage by running on a single process.

WezTerm
WezTerm is a high-performance, cross-platform terminal emulator and multiplexer built in Rust that delivers GPU-accelerated rendering, including ligatures, color emoji, true color, dynamic color schemes, and hyperlinks, and modern windowing controls such as panes, tabs, and multiple windows on both local and remote hosts. Its single-process multiplexer provides scrollback, searchable history, mouse integration, Quick Select mode for rapid selection, Copy mode, shell integration, support for the iTerm image protocol, SSH connectivity, serial ports, Arduino devices, and workspace/session management via Lua-configurable scripts. Configuration is handled through a wezterm.lua file with hot-reload support, while a rich command-line interface (wezterm cli) lets you spawn programs, manipulate tabs and panes, and set domains. WezTerm adheres to ECMA-48 and xterm conventions for full ANSI/ISO compliance and offers native UI integration using platform-specific APIs.
