A multi-platform HTML5 application wrapper.

Zephyros is a library/framework which provides a native application shell for HTML5 desktop apps.

Zephyros enables you to create your GUI in HTML5/CSS and write your application logic in JavaScript. For operating system functionality which can't be accessed normally by JavaScript, Zephyros provides an easily extensible native layer.

Currently, Mac and Windows are supported. The Linux version still lacks implementation of some native features, but if you don't need them, you're good to go. (Please note, however, that the Linux version uses GTK3 and the default branch no longer builds on Linux because CEF introduced an incompatibility; for Linux, please use the develop-cef2623 branch.)

On Windows and Linux, the Chromium browser is used via the Chromium Embedded Framework (CEF); on Mac you have the choice between CEF and the native WebView, which is based on Safari. Note that if you want to publish and sell your app on the Mac AppStore, you should use WebView (using CEF will most likely get the app rejected).

This project is similar to Adobe's brackets-shell or Github's Electron. The differences are that Zephyros gives the option to use WebView on Mac (for compatibility with the AppStore), and that Zephyros provides (in our opinion) a more easily extensible JavaScript extension ("native") layer.

Another difference is that Zephyros is packaged as a library (a static library on Windows and a framework on Mac, against which you link your own app), so whenever Zephyros is updated you only need to update the library, not your source code. (In release 1 of Zephyros, this was different; Zephyros was the base on which you could build your app (just like brackets-shell). If you're looking for that, you can still find it in the "Release-1" branch.)

In addition, Zephyros comes with built-in licensing allowing you to build demo and paid versions of your app, and the in-app updater Sparkle / WinSparkle.

Please have a look at the Wiki for instructions how to create your Zephyros apps.

The project is licensend under the MIT license.
