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.

xterm is a terminal emulator for the X Window System, first released to emulate DEC VT102 and Tektronix 4014 hardware and provide a windowed interface for applications that cannot access X directly. Each xterm window runs as a separate process, locally or remotely, while sharing keyboard and mouse input with only the focused window receiving events. It implements ANSI/ISO color support via the “new” color model for background erase and recognizes most VT220 control sequences, along with select features from VT320, VT420, and VT520 devices. Over its history, xterm’s terminal description evolved from VT102 (pre-1996) to VT220 (1996–2012) and, since 2012, to VT420, ensuring compatibility with modern applications. Xterm remains actively maintained and extensible through companion tools like luit for encoding support and the X Toolkit for resource configuration, making it a complete, standards-compliant emulator for Unix-based environments.
