Exstats is a platform that unifies browser extension analytics and market research across Chrome, Edge, and Firefox. It addresses the problem of fragmented data across different extension stores, making it difficult for builders to understand product performance, competitor activity, keyword relevance, and market changes. The main purpose is to bring all this information into one unified view for better market visibility. Key features include the ability to track your own extensions across Chrome, Edge, and Firefox. You can monitor competitors, including their ratings, reviews, rankings, and keyword positions. The platform provides access to explore over 280,000 browser extensions with advanced filters. Users can follow store and category trends to understand market movements. Additional capabilities include receiving daily updates on metrics, the ability to export data, and configurable alert systems. The platform keeps historical snapshots of data, allowing users to see trends over time for ratings, installs, users, and rankings. It pulls reviews into a unified view across all stores, eliminating the need to check each listing manually. The product works by collecting data from public extension store listings. Crawlers run once a day after midnight UTC to gather daily snapshots, keeping updates consistent and comparable. The approach normalizes data where fair comparison is possible, though it provides context for differences between stores, such as Chrome showing weekly users, Firefox having average daily users, and Edge being closer to installs/users. Benefits include saving time by eliminating manual checking across multiple stores. It provides better visibility into the extension market for product development and growth strategies. Use cases involve tracking extension performance, conducting competitor analysis, monitoring keyword positions, and observing store trends to inform business decisions. The target users are extension founders, indie makers, agencies, and teams that want better visibility into their market. It is built for anyone building or growing browser extensions. The platform covers Chrome Web Store, Firefox AMO (Add-ons), and Microsoft Edge Add-ons, providing a comprehensive cross-store analytics solution.
