A website cannot force a universal install prompt. Chromium browsers may expose an install button when their criteria are satisfied, while Safari uses Share and Add to Home Screen flows.
The test reports the public signals that influence those flows and explains where manual user guidance is still necessary.
Browsers implement PWA installation and operating-system integration differently. Manifest quality, service worker behaviour and user engagement can all affect the available UI.
Treat the matrix as practical readiness guidance rather than a promise that every device will show the same button.
Short answers about what the public tool checks and what remains under browser or website-owner control.
No. Safari does not expose the same cross-origin install prompt used by Chromium. Users must open the original website and choose Add to Home Screen.
Browser heuristics, previously installed state, engagement, policy and platform differences can suppress the prompt even when manifest signals look correct.
No. It is a read-only inspection. Installation always happens on the original website under browser control.
