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 to compare a release against a competitor over time.
Exstats fixes this by grouping the Chrome, Edge, and Firefox versions of an extension into one product view, alongside the competitors you want to watch. It tracks daily changes in installs, ratings, reviews, category rank, and search rank, then keeps up to a full year of history so weekly and monthly trends are visible at a glance. Email and Slack alerts fire on rating drops, rank shifts, and competitor updates so a regression does not sit unnoticed for a week.
Beyond your own products, the Extension Explorer indexes 280,000+ extensions with 30+ searchable fields and exportable CSV or XLSX, the Keyword Tracker suggests AI-generated keyword ideas and tracks rank by store, and the Store Trends dashboard reports category growth, rating distributions, and review activity across each store.
Handler is a vibe marketing agent for app marketers. It helps app teams find outlier TikToks, understand what makes them work, and turn proven patterns into clearer creative direction. Todayโs launch focuses on Handler and TikSpy: research winners faster, reduce manual scrolling, and know what to test next.
Exstats HandlerExstats'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.
Handler's answer:
Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.
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.
Handler's answer:
Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.
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.
Handler's answer:
Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from โwhat should we post?โ to clear creative direction based on real winning TikToks.
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.
Handler's answer:
Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.
Handler's answer:
Handler uses AI analysis, TikTok content research, video metadata extraction, creative pattern detection, and a web-based dashboard to help app marketers find and understand winning TikToks.
Handler's answer:
Handler is currently early, so we are not publishing customer names yet. The product is built for app founders, consumer app teams, growth marketers, and agencies working on TikTok-based app growth.
