Atom is an open‑source, cross‑platform text editor developed by GitHub, designed to be deeply customizable through a vibrant ecosystem of packages and themes. It supports a wide range of programming languages and integrates with Git and GitHub for seamless version control workflows. Although officially sunset in December 2022, Atom remains usable and community‑maintained, offering a flexible environment for developers who value extensibility and a modern UI built on web technologies.
Nova is a code editor and lightweight IDE built exclusively for macOS by Panic, the makers of Transmit and Coda. It uses native Apple frameworks for speed and responsiveness, combining a text editor, file transfer client, and Git client in one focused workspace. Nova ships with built-in debugging, task runners for build and run commands, and live web previews that update as you type. Its extension system is written in JavaScript and covers everything from language servers to custom sidebars, and Nova includes first-class support for Rust, Swift, and C/C++ alongside general web development languages.
