If you want to build true progressive web apps, use our open source platform.

https://qbix.com/platform

We spent literally YEARS on all aspects of making these progressive web apps, including:

* Making each component we build (chatrooms, image upload etc.) work out of the box on whatever environment it’s loaded. For instance resizing and cropping an image on the desktop involves the mouse wheel while the same thing on touchscreens involves the fingers. See this: https://vimeo.com/208438090

* Taking advantage of the latest changes like SFAuthenticationSession on iOS

* Writing our own cordova plugins when the existing ones were not working, available for free as open source on github

* We support ApplePay, AndroidPay, Web PaymentRequest for Chrome and Firefox on Android and desktop and even looking to do Safari for Mac.

* We support notifications on iOS and Android native apps, as well as Web Push for all web browsers that support it. And we plan to make encrypted notifications via VoIP on iOS and some tricks on Android.

* As time goes on we will add end to end encryption beyond what is available on the Web today, see http://qbix.com/blog

* Oh and we are in the process of building a mobile HTML editor that sucks less than all the others (though we have not freely licensed it yet! Contact us!) http://d3e.ru/sel/demo/#1

* We have instant personalization, invitations, access control. We have a passwordless authentication as invited users go to the site via a link that instantly confirms their number/email, see their friends who uploaded their address book, download the app and then use SFAuthenticationSession to continue where they left off.

* We plan to write our own mobile browser to make people have social experiences across websites without Facebook. We also speak with the SAFE Network team to add support.

* The former lead developer of the solid project (solid.mit.edu) has come on board to help us realize our vision for qbix platform 2.0 https://qbix.com/blog/2018/04/03/onward-to-qbix-platform-2-0...

I wish you'd linked to the github repo, which has the LICENSE file in it... first thing I looked for and had to click around a bit to find it.
