Web apps don’t even use half of the features available and that’s sad. I use a lot of recipe websites and almost not a single one uses the Wake Lock API to keep the screen on, which is really what you need when cooking. This is why people think native apps are better 😞

The killer feature of PWAs is not that they update automatically or they’re cross-platform. The absolute killer feature of PWAs is that they can be freely distributed without any app store dependency No risk that one party can kill your distribution and end your business. That’s a killer feature.

If your web app sends push notifications that don't show up on Samsung phones, here's what you need to know x.com/dannymoerker...

In an attempt to make the installation flow on iOS clearer, I added a wizard-like vertical progress stepper to the installation steps with screenshots. Hopefully, this will make it clear that there are more steps outside the viewport, and the user needs to scroll down:

I added the <geolocation> element to the Geolocation demo of What PWA Can Do Today. The benefit of this element is that you can simply click it again if permission was previously denied, so you don't have to dig through browser settings. 🧵1/2

Chrome 153 now supports the <camera> and <microphone> elements. These elements do the same as getUserMedia(), but when access is denied, you can simply click it again to grant access, so users don't need to dig through browser settings to reset permissions. Demo link👇

iOS27 beta 6 adds a weird blur to the top of the screen, but only when the PWA is added to the Home Screen 🤷‍♂️ Oh, and the Share option to add it to the Home Screen is in a different place, again...

By popular demand, I added a capabilities page to What PWA Can Do Today, which lists all capabilities on one page and indicates for each one if it's supported on your device. You can filter by support and search for capabilities. whatpwacando.today/capabilities/

Most PWA issues only appear at runtime: - Does it still work without network? - Does a new version activate cleanly? - Are users getting fresh files or old cached ones? - Can people actually install it? pwa.today tests that runtime behavior. Run a quick free check or add CI/CD audits. pwa.today

Whatsapp Web is now a PWA... but not on mobile 😞 It could be, but Whatsapp chose not to make it available on mobile, only on desktop. This reinforces the idea that PWAs are inferior to native apps. If Whatsapp doesn't do it, it's probably not possible, right? 🧵1/3

On iOS 26.5, you no longer need to add the meta tag <meta name="apple-mobile-web-app-capable" content="yes"> to show splash screens on iOS. This tag is deprecated since iOS 11.3, but it was still needed to show splash screens on iOS. Since iOS 26.5, this is no longer the case 🧵1/2

Out-of-order streaming HTML is coming to a browser near you! This means you can stream HTML to the browser in any order, which enables web apps to send the most important HTML first, regardless of where it is in the document. This is huuuuuge! 🧵1/3

I don’t think HTML-in-canvas is the biggest revolution in HTML right now. I think another feature is. One that will be truly revolutionary and that will have cross-browser support very soon. Details in tomorrow’s edition of Modern Web Weekly. Subscribe link 👇

Your web app can read and write files on the user’s device and request persistent storage so it’ll never lose data again, even if it’s not used for a while. Check the details in Modernn Web Weekly 73 Subscribe link 👇

Don't wait for iOS support to make your PWA installable. If we can teach users 4 clicks to add a web app to their favorites, we can teach them how to install a web app. Users are not unfamiliar with PWAs because of the lack of iOS support. It's because we don't build enough of them. 🧵 1/2
