Progressive Web App (PWA)

Using a PWA allows Kasm to provide a similar experience to that of a mobile app installed from an App Store.

Benefits for the user:

  • Small size - you aren’t installing a full application.

  • Instant updates - It’s still a website, so updates to the site are available immediately to the PWA.

  • Add to homescreen - Just as you would any application.

  • Tabless window - No more annoying browser bars reducing useful space available.


Unfortunately PWA installation isn’t universal across platforms or even devices on platforms. Some platforms prompt you to install the app when you visit a site that has PWA functionality, some just show it in the browser bar, and some don’t show anything at all (iOS).


Using Chrome on Android tends to give the best PWA experience, and will pop up with an option to install the PWA when you go to the site. With Firefox, you need to click on the three dots next to the browser bar and then go to Install App, this also works with Chrome if you close the prompt and then later decide you want to install it.


Installing on Android


iOS doesn’t give any indication that a PWA is available and a PWA can only be installed via Safari.

  1. Open Safari and navigate to the site.

  2. Click on the Share icon.

  3. Scroll down until you find the option “Add to Home Screen” and click on it

  4. Click the “Add” button


Installing on iOS

Desktop Browsers

Safari on MacOS does not give an option to install a PWA at all at this time.

All other browsers seem to show the option both in the browser URL bar or as an option when you click the three dots.
