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.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

Questions & Answers

As answered by people managing Exstats and KnowCSS.

What makes your product unique?

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.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.
