Exstats — Browser Extension Analytics for Chrome, Edge & Firefox

# Exstats > Exstats is a browser extension analytics platform that crawls Chrome Web Store, Edge Add-ons, and Firefox Add-ons daily, collecting ratings, users, reviews, categories, rankings, and more for 280,000+ extensions. It helps extension developers and marketers track performance, monitor competitors, research the market, and set up alerts — all from one dashboard. Key concepts: - A **Product** groups listings of the same extension across different stores (e.g. Chrome + Edge + Firefox) and optionally includes competitor extensions for side-by-side comparison - A **Listing** is a specific extension in a specific store — the atomic unit of tracked data - An **Alert** is a monitoring rule attached to a listing that notifies you on changes (rating drops, ranking shifts, field updates) via email or Slack, on a daily/weekly/monthly schedule - **Tracked Keywords** are search terms attached to a product, used to monitor your extension's ranking position in store search results across all three stores - Store metrics differ: Chrome shows weekly active users, Edge shows active install count, Firefox shows average daily users — Exstats shows each as-is without combining them ## Platform - [Products](https://app.exstats.com/products): Create products that group your extension listings across Chrome, Edge, and Firefox.
