Atom is a discontinued open-source text editor that's deeply hackable and customizable, built for developers who want to tailor their coding environment using web technologies.

---

🚀 Overview

Atom, launched by GitHub in 2014, is a free and open-source code editor designed to be the 'hackable text editor for the 21st Century.' It addresses the limitations of traditional editors by allowing full customization through JavaScript packages, themes, and keybindings, making it approachable for beginners yet powerful for experts.

The project solves the need for a modern, extensible editor that feels native on desktop while leveraging web tech. It was built for software developers, open-source contributors, and anyone in the coding community wanting to build software more easily. GitHub created it to grow the creator community, but discontinued it in 2022 to prioritize VS Code and cloud tools like GitHub Codespaces.
