Answer

Can a PWA access the camera?

Short answer

Yes. A PWA can access the camera, microphone, geolocation and file system through the same Web APIs a regular website uses (getUserMedia, showOpenFilePicker, Geolocation). Every capability requires explicit user permission and works cross-platform, though a few APIs (Bluetooth, USB, NFC) are still Chromium-only.

What works everywhere

Camera and microphone (getUserMedia), geolocation, notifications, share sheet, clipboard read/write, screen wake lock.

What is Chromium-only

File System Access API (full read/write), Web Bluetooth, Web USB, Web NFC, contact picker.

iOS Safari caveats

getUserMedia works but requires HTTPS and a user gesture. Screen recording via getDisplayMedia is desktop-Safari only.

A PWA (Progressive Web App) is a regular website that meets three technical criteria — HTTPS, a Web App Manifest and a service worker — so browsers let visitors install it on their home screen. Once installed, it launches like a native app, works offline and can send push notifications.

Do PWAs work on iPhone?

Yes. Since iOS 16.4 (March 2023), iPhone and iPad support the full PWA feature set: install to home screen from Safari, standalone launch, offline via service worker, and Web Push notifications. The install step is manual — Safari does not show a browser prompt; users must tap Share → Add to Home Screen.

Does a PWA help or hurt SEO?

A PWA does not directly change your Google ranking. Googlebot indexes your HTML the same whether or not you have a service worker. The indirect effect is Core Web Vitals: repeat visits from installed users have near-zero TTFB and better INP, which improves your CWV score and, over time, ranking.

What are the requirements for the Chrome install prompt?

Chrome fires beforeinstallprompt when the site is served over HTTPS, links a valid manifest with name, start_url and 192px + 512px icons, registers a service worker with a fetch handler, and passes a user-engagement heuristic (typically one interaction and ~30 seconds of use). Any failing criterion silently blocks the prompt.

Can PWAs accept payments?

Yes. A PWA can accept payments through any standard web checkout — Stripe, PayPal, Adyen — and can also use the native Payment Request API to surface Apple Pay on iOS 16.4+ and Google Pay on Android. There is no App Store 30% cut because payments run through the web, not through a native store SDK.
