I've been publishing Chrome extensions for a while now, and the stats page in the developer dashboard always feels incomplete. You can download stats as a CSV, but making any sense from them is extremely hard and tedious.
So I built WebstoreStats over a weekend to scratch my own itch. You drop in your CSV exports, and it gives you a real dashboard.
Some stuff it figures out for you:
How many people see your extension in search, vs actually click through, vs install. Shows how many people actually convert.
Smoothed install trends so you're not squinting at random daily spikes trying to guess if things are going up or down
Which countries have good retention, and which ones uninstall fast
How quickly users pick up a new version after you push it
Whether people are disabling your extension over time
What % of people who land on your listing page actually hit install
You can also mark dates when you shipped an update or changed your listing — they show up as lines on the charts, which is super helpful for seeing "did that change actually do anything?"
No login, no server, free forever. It's a static site. Your CSVs get parsed in the browser, and that's it; nothing leaves your browser.
Would love to get feedback and see what more I can add.
