Yes! We're working hard to add support for Microsoft Windows devices - we hope to release an alpha version soon.

We don't have plans to target Linux in the near future. Right now we are focused on developing a Windows version of the Feather runtime environment and adding Windows and Mac support for popular Flutter plugins.

The Feather App Store is currently free for all developers. In future we plan to charge a 5% fee when your end users make a purchase in a Feather app.

Yes, you distribute your binary executable any way you like - for example, you can upload it to the Mac App Store or put it on your website.

Feather is actually based on the flutter-desktop-embedding project. Currently for Mac it offers the same features plus:
(a) More functionality like copy and paste, mouse wheel and escape key
(b) More supported plugins like shared_preferences, url_launcher, google_sign_in
(c) An easy way to publish your app and push updates to end users

Feather is still in alpha testing phase - this means it is not yet stable enough for publishing large-scale reliable apps. Please subscribe to our email newsletter below to be notified of beta and stable releases. In the meantime try deploying internal or small-scale test apps.
