Free, open source, hackable text editor
Atom is a free text editor that's modern, approachable, yet hackable to the core—a tool you can customize to do anything but also use productively without ever touching a config file.
Atom works across operating systems. You can use it on OS X, Windows, or Linux.
Built-in package manager
Search for and install new packages or start creating your own—all from within Atom.
Atom comes pre-installed with four UI and eight syntax themes in both dark and light colors. If you can't find what you're looking for, you can also install themes created by the Atom community or create your own.
Atom helps you write code faster with a smart, flexible autocomplete.
File system browser
Easily browse and open a single file, a whole project, or multiple projects in one window.
Split your Atom interface into multiple panes to compare and edit code across files.
Find and replace
Find, preview, and replace text as you type in a file or across all your projects.
