N1 is an open-source mail client built on the modern web with Electron, React, and Flux. It is designed to be extensible, so it's easy to create new experiences and workflows around email. N1 is built on the Nylas Sync Engine, which is also open-source free software.

You can download compiled versions of N1 for Windows, Mac OS X, and Linux (.deb) from https://nylas.com/N1. You can also build and run N1 on Fedora. A Fedora distribution is coming soon! On Arch Linux, you can install n1 or n1-git from the aur.
Plugins lie at the heart of N1 and give it its powerful features. Building your own plugins allows you to integrate the app with other tools, experiment with new workflows, and more. Follow the Getting Started guide to write your first plugin in five minutes. To create your own theme, go to our Theme Starter guide.
If you would like to run the N1 source and contribute, check out our contributing guide.
We're working on building a plugin index that makes it super easy to add them to N1. For now, check out the list below! (Feel free to submit a PR if you build a plugin and want it featured here.)
