Quality standard

Simple awards, verified evidence

Awards make strong PWA experiences easy to recognize without turning an app page into a technical report.

App-Grade
A complete, polished PWA foundation with working install information and a checked mobile experience.
Fast
Live field data
Real-user Core Web Vitals (LCP, INP, and CLS p75) from the Chrome UX Report, refreshed periodically.
Modern Install
A verified integration with an experimental modern web installation mechanism.
What makes an app App-Grade
Every check must pass. A declaration only counts when the crawler can verify the important parts.
  • A valid manifest with a clear app name
  • An explicit, stable app ID
  • An explicit start URL that launches successfully
  • An app-like window mode
  • A decoded 512px or larger manifest icon
  • A manifest description and a verified manifest screenshot
  • A successful mobile render without serious horizontal overflow
How checks are handled

Evidence, not assumptions

PWAStore checks manifest data, fetched assets, and a real browser render. A declaration alone does not prove that an app works.

Missing data is neutral

An app is never shown as slow because field data is unavailable. Missing measurements are not converted to zero.

Checks are versioned

Every assessment records when it ran and which evaluator version produced it, so criteria can improve over time.

Experimental means experimental

Modern Install recognizes detected integration. It does not promise support in every browser or on every device.

The public award explains the result in plain language. Its details sheet shows the checks behind that result and when they were last completed.
