Hey everyone!
I recently made a cross platform GUI application for node-webkit that streamlines the process of exporting your web app to a standalone app. It basically removes the need to dabble with the command line, auto generates the json file from options selected, zips your project up and adds it to the node-webkit executable automatically. You can also export to multiple platforms simultaneously. I made this app for myself because I found manually packaging the node-webkit app every time I changed something to be cumbersome, so I thought I'd share it with the interwebs :)
On the page, you'll find pre-built binaries for Windows, Mac and Ubuntu. The UI is the same for all platforms and it makes it much easier to export your web application.
Please add an issue to the github page if you run into any bugs. This is a beta software, but it should be stable to use.
Anyway, enjoy! :)
