1. PPSPY
PPSPY tracks a Shopify competitor’s sales with its own AI estimate of orders, gives a 15-day sales report, and filters stores by revenue, traffic, theme and apps. It also finds best sellers and one-product stores.
- Sales figures are its predictions, not store data
2. ShopHunter
ShopHunter estimates a Shopify store’s revenue, orders and average price, with historical sales trends, best sellers and Facebook ads, and filters products by sales speed and store size.
3. Sitepeel Shopify theme detector
Paste any store page to see its theme name, version and Theme Store page, or a note that it’s a custom theme. The tech stack checker adds the libraries and analytics it can see.
- No sales, revenue, traffic or ads data
- It names the theme, not the apps or changes a store added
When Koala Inspector is the better pick
- You want best sellers, apps and theme in one Chrome extension, free
- You like app and theme detection that costs no tokens
- You want to watch up to 50 stores on Premium
- You can live with estimates: its listing says sales and traffic are not verified numbers
Which one should you pick?
Questions
Is Koala Inspector free?
Yes, it has a free plan with store structure, app and theme detection, best sellers and 15 tokens a month for deeper data. Traffic, ads and suppliers cost tokens.
How much does Koala Inspector cost?
Premium is $22 a month with 220 tokens. Extra token packs cost $3.99 for 10, $6.99 for 25 and $11.99 for 100, and they don’t expire.
Are Koala Inspector’s sales numbers accurate?
They’re estimates. Its own listing says sales and traffic figures aren’t verified numbers, so use them to compare stores, not as exact results.
What happened to Commerce Inspector?
We found no Chrome listing under that name on November 5, 2026, and its domain redirects to a page that says “Site not found”. We couldn’t confirm why.
Does Sitepeel show Shopify sales?
No. Sitepeel’s free Shopify theme detector names the theme, its version and its Theme Store page. For sales estimates, use one of the research tools above.
