What are the limitations of the PWA Client App compared to the other solutions?

  1. As of now (2021 February) the app cannot run on device startup. You have to start it manually.
  2. It cannot go fullscreen automatically – only if the user gives permission by a single click.
  3. If you want to get screenshots from the device, you have to manually give permission.
  4. It has limited access to device hardware. For example to serial or USB connection.
  5. And if it has access, the user has to give explicit permission either only once or sometimes on every app start.

Why would you choose the PWA Client App over its Android, Windows, etc version? And who should choose this?

If you have a shop/company/restaurant etc where you have a maximum number of 5 to 10 screens and they do not need to access any special hardware capabilities (for example using the serial bus) then
it is very tempting to choose the PWA Client App because it is fast, reliable and very easy to install / setup. If you do not mind turning on each of your devices in the morning and clicking a few times
to have the app running flawlessly all day long then this solution can be perfect for you.

The future of the PWA technology

Google, Microsoft, Intel, and Samsung run a joint effort to close the gaps between the capabilities of the web and native apps thus there will always be a few more new things that PWA apps can do in the future.

One more thing to mention

In 2021 the Chrome browser lets you use the most web technologies needed by web apps, but the app runs in Edge, Safari, Firefox, Opera, and Samsung browser too just to name a few.
Basically, all modern browsers are and will be good in the foreseeable future.
