Question 1

What does the PWA Readiness Checker test?

Accepted Answer

It checks the core requirements for a Progressive Web App: HTTPS, a linked web app manifest (manifest.json), a registered service worker, a viewport meta tag, a theme-color meta tag, an Apple touch icon, and a favicon. Each check returns a pass, fail, or warning with a fix suggestion.

Question 2

Why does my site fail the service worker check?

Accepted Answer

The service worker check detects whether a site registers a service worker by examining the page source for a serviceWorker.register call. If your site uses a framework that registers the service worker at runtime (e.g. after JavaScript executes), it may not be detected. You can add a service worker manually or use Appifya to generate one automatically.

Question 3

My site uses HTTPS but the check failed — why?

Accepted Answer

Some sites block external requests (CORS, firewalls, Cloudflare bot protection). If the checker cannot fetch your page, it will report the check as blocked rather than failed, and your actual HTTPS status is still valid.

Question 4

What is a web app manifest and why does it matter?

Accepted Answer

A web app manifest is a JSON file (manifest.json) that tells the browser your app's name, icons, theme color, and display mode. Without it, browsers cannot offer an "Add to Home Screen" prompt and your site cannot be installed as a PWA.

Question 5

How do I fix the issues the checker finds?

Accepted Answer

Each failed check includes a specific fix suggestion. For missing manifests, use the free Manifest Generator tool. For missing icons, use the Icon Generator. For a complete PWA setup including service worker and APK export, use the Appifya builder.
