Emacs is a text editor, code development IDE, and, perhaps, a hidden operating system, which runs on several operating systems regardless of the machine type. The main
ones are: GNU, GNU/Linux, FreeBSD, NetBSD, OpenBSD, macOS, MS Windows, and Solaris.

Emacs /ˈiːmæks/ is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on its direct descendant, GNU Emacs, continues actively as of 2018.

Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macros to automate work. Implementations of Emacs typically feature a dialect of the Lisp programming language that provides a deep extension capability, allowing users and developers to write new commands and applications for the editor. Extensions have been written to manage email, files, outlines, and RSS feeds, as well as clones of ELIZA, Pong, Conway's Life, Snake and Tetris.
