A hackable text editor for the 21st Century
Atom is a free and open-source text and source-code editor for macOS, Linux, and Windows with support for plug-ins written in JavaScript, and embedded Git control. Developed by GitHub, Atom was released on June 25, 2015.
On June 8, 2022, GitHub announced Atom's end-of-life, occurring on December 15 of the same year, justifying its need "to prioritize technologies that enable the future of software development", specifically its GitHub Codespaces and Visual Studio Code, developed by Microsoft which had acquired GitHub in 2018.
