Most browser extension developers ship the same product to Chrome, Edge, and Firefox, then try to track its performance across three separate developer dashboards, three different review feeds, and three sets of keyword rankings. The data is fragmented, history is short, and there is no easy way...

As answered by people managing Codility and Exstats.
Exstats's answer:
Exstats treats an extension as one product across stores, not as three separate listings on three sites. The Chrome, Edge, and Firefox versions sit in one row, and history, reviews, alerts, and competitor data flow from there.
Exstats's answer:
Exstats started because developers shipping browser extensions kept running into the same wall. The Chrome Web Store, Edge Add-ons, and Firefox Add-ons each give publishers a siloed view with short history, no competitor data, and no way to compare a release against a rival over time. Teams that maintained extensions on more than one store ended up checking three dashboards a day and keeping competitor numbers in spreadsheets. We built Exstats so an extension and its store versions live in one place, with daily history, alerts, and competitor tracking built in.
Exstats's answer:
Unified multi-browser view. Exstats is the only dashboard that groups the Chrome, Edge, and Firefox versions of an extension into one product, with shared history and shared alerts. Most analytics tools cover only the Chrome Web Store, or split the three stores across separate sites.
Full year of daily history. Stores show current numbers and a short trail. Exstats keeps daily snapshots for up to a year so weekly and monthly trends, rating regressions, and competitor launches are visible at a glance.
Reviews from every store in one table. Chrome, Edge, and Firefox reviews sit in one sortable, filterable table, so a developer can read a week of feedback without rotating between three dashboards.
Keyword tracking with AI suggestions. Search rank is tracked per store with daily change indicators, and the keyword tool suggests new keywords from competitor listings rather than expecting the developer to bring a complete list.
Exstats's answer:
Exstats is built for the people shipping and growing browser extensions.
The core audience is independent extension developers and small product teams who need one place to watch installs, ratings, reviews, and keyword rank for their extensions, on whichever stores they publish to.
A second audience is extension growth and marketing specialists who track competitor launches, rating shifts, and category trends on behalf of clients and need a single view across Chrome, Edge, and Firefox rather than three separate workflows.
A third audience is product and engineering teams at companies whose extension is a meaningful acquisition or retention surface, who need daily alerts, exportable data, and API access for internal dashboards.
