About Chrome-Stats
Marketplace data for extensions and apps
Chrome-Stats tracks public marketplace data for browser extensions and mobile apps so developers, researchers, organizations, and users can inspect store-level counts, historical trends, ranking signals, and safety-related metadata in one place.
Public store coverage
We collect public listing data from Chrome Web Store, Edge Add-on Store, Firefox Add-ons Store, Google Play Store, and Apple App Store.
Historical snapshots
Public statistics pages are built from stable daily snapshots, and each snapshot is available as a CSV export.
Risk context
Risk indicators combine public marketplace data with observable technical metadata such as permissions, host permissions, manifest data, and historical changes.
How Chrome-Stats works
Chrome-Stats crawls public store pages, category and collection pages, listing surfaces, and store sitemap feeds where they are available. We normalize the resulting records into a common model for analytics while preserving store-specific distinctions such as Android download ranges, browser-extension user counts, and Apple device support.
Store-provided values can be rounded, delayed, localized, region-specific, or temporarily unavailable. For that reason, Chrome-Stats counts should be treated as third-party marketplace estimates rather than official store totals.
Some extensions or apps may not appear on Chrome-Stats even if they exist in a store. This can happen when a developer requests removal from the website.
