Hi Product Hunt 👋
I’m Artur, founder of Exstats.
I built Exstats because browser extension data is fragmented across Chrome Web Store, Microsoft Edge Add-ons, and Firefox Add-ons. If you’re building an extension, it’s hard to understand how your product is performing, what competitors are doing, which keywords matter, and how the market is changing.
Exstats brings all of that into one unified view.
With Exstats, you can:
* Track your extensions across Chrome, Edge, and Firefox
* Monitor competitors, ratings, reviews, rankings, and keyword positions
* Explore 280K+ browser extensions with advanced filters
* Follow store and category trends
* Get daily updates, exports, and alerts
It’s built for extension founders, indie makers, agencies, and teams that want better visibility into their market.
I’d love to hear your feedback, especially from anyone building or growing browser extensions. What would you want to track that extension stores don’t show today?
Thanks for checking it out.
Best,
Artur
@nowaffl this looks practical for extension teams. Comparing Chrome, Edge and Firefox in one place would save a lot of manual checking. Do you send alerts when a competitor suddenly moves in rankings or gets a spike in reviews?
Exstats
@busra_seker1 Yes, alerts are supported.
You can pick almost any metric to watch, like rankings, ratings, installs/users, or review count, and get notified when it changes.
For more specific cases, you can also set custom rules, like when a metric grows or drops by a certain percentage, crosses a threshold, or reaches a specific value. It’s all configurable in the alert settings.
The approach of normalizing extension store metrics into a unified dashboard is clever. Chrome Web Store doesn't provide a real analytics API, so you're likely scraping review counts and rating distributions yourself. We've dealt with similar data gaps when tracking third-party integration adoption across platforms. How do you handle rate limiting on store data collection, and do you support Firefox AMO alongside Chrome?
Exstats
@anand_thakkar1 Thanks, you’re right, Chrome Web Store doesn’t really provide an API for this. Finding a reliable way around that wasn’t exactly easy haha.
The data comes from public store listings, and we keep the collection fairly conservative. Metrics are refreshed on a daily schedule rather than continuously.
And yes, Firefox AMO is supported, along with Chrome and Edge.
Tracking extension metrics across the Chrome Web Store is harder than it looks without an official API. We've hit the scraped-data freshness problem in our own analytics work, where stale snapshots quickly become noise. How do you handle rate limits and anti-scraping on store crawlers, and do you normalize data across Firefox and Edge addon stores?
Exstats
@retain_dev Yeah, the lack of a proper Chrome Web Store API definitely makes this trickier than it should be.
For data updates, we keep things conservative and refresh everything on a daily schedule, which has been enough to stay stable without making the snapshots too noisy.
For normalization, we do it where comparison is fair. Ratings, reviews, and rankings map well, but users need context since Chrome shows weekly users, Firefox has average daily users, and Edge is closer to installs/users.
Most extension analytics tools stop at your own store listing. The competitor tracking angle is the more interesting half here.
How granular does it get on competitor data, are you pulling review sentiment and rating trends over time, or is it mostly install counts and category rankings? And does it cover both Chrome Web Store and Firefox/Edge, or Chrome only right now?
Congrats for the launch
Exstats
@fberrez1 Thanks, appreciate it!
All three stores are covered, Chrome Web Store, Firefox, and Edge.
On the competitor side, we track public store data and keep historical snapshots, so you can see trends over time for ratings, installs/users, rankings, and other key metrics instead of only seeing today’s numbers.
Reviews are already pulled into one unified view across all stores, so you don’t have to check each listing manually. Sentiment analysis isn’t live yet, but it’s on the roadmap and should be coming soon.
Exstats
@motionbyayo Thanks!
Yes, you can open a competitor and see historical charts for any available numeric metric, like rating, reviews, users, rankings, and so on.
So if a rating started dropping after a bad update, you should be able to see that trend over time, not just compare today with last month.
There are also pre-calculated 1d, 7d, and 30d changes for quick recent comparisons.
Congrats on the launch @nowaffl ! How exactly do you get the competitor info? And how real time is it?
Exstats
@aiswarya_s Thanks!
Competitor data is collected from public extension store listings. Crawlers run once a day after midnight UTC, roughly around the same time, to keep daily snapshots consistent and easier to compare.
So for now, metrics and alerts are updated daily rather than in real time.
Custom alerts for every metric sounds powerful. But the more you can track, the more noise you can create. What do people actually end up watching - is there a pattern in what turns out to be worth the alert? Congrats on the launch!
Exstats
@jared_salois Too early to say yet, the public launch just happened.
My guess is rankings and keyword positions, but we’ll see from real usage. And thanks for the kind words!
