Updated yesterday. Ext Watch checks public store pages itself. The numbers are from that check, not live usage.

What this page does not cover

Written reviews come from licensed review data, not from scraping the store’s review pages, so we may hold only part of them and developer replies may be missing. We don’t track store ranking history or look inside the extension’s code. The store’s user count isn’t total installs ever, and it isn’t revenue.

Related products and access lists are starting points for research, not recommendations or safety checks.
