At GitHub, we’re building the text editor we’ve always wanted: hackable to the core, but approachable on the first day without ever touching a config file. We can’t wait to see what you build with it.

Teletype for Atom

Great things happen when developers work together — from teaching and sharing knowledge to building better software. Teletype for Atom makes collaborating on code just as easy as it is to code alone, right from your editor.

Share your workspace and edit code together in real time. To start collaborating, open Teletype in Atom and install the package.

GitHub for Atom

A text editor is at the core of a developer’s toolbox, but it doesn’t usually work alone. Work with Git and GitHub directly from Atom with the GitHub package.

Create new branches, stage and commit, push and pull, resolve merge conflicts, view pull requests and more — all from within your editor. The GitHub package is already bundled with Atom, so you’re ready to go!

Make it your editor

Packages

Choose from thousands of open source packages that add new features and functionality to Atom, or build a package from scratch and publish it for everyone else to use.

Themes

Atom comes pre-installed with four UI and eight syntax themes in both dark and light colors. Can’t find what you’re looking for? Install themes created by the Atom community or create your own.

Customization

It’s easy to customize and style Atom. Tweak the look and feel of your UI with CSS/Less, and add major features with HTML and JavaScript.

Under the hood

Atom is a desktop application built with HTML, JavaScript, CSS, and Node.js integration. It runs on Electron, a framework for building cross platform apps using web technologies.
