Atom is multiplatform (Windows, Linux, and Mac) and allows cross-platform use for your projects. Customization is the IDE's biggest appeal: At time of writing, there are more than 2,000 packages and 600 themes.

• 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.
• Features AIM-65 Intel® Atom™ processor for Windows 10 IoT and AIM Android 6.0 8' WUXGA full HD display with scratch-resistant Corning® Gorilla® Glass 3.

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.
