Competitor data, right in your browser
Stop guessing, start selling.
See what any Shopify store sells, which apps it runs, and where its traffic comes from. Koala Inspector puts that data one click away.
The data you need, before you spend a dollar
Most merchants pick products by gut feel, then find out six weeks later the market was already crowded. The ones who grow fastest start by studying what already works in their niche.
Analyze. Learn. Grow.
What Shopify spy tools actually do
A Shopify spy tool reads the publicly accessible signals a store sends out: its theme, installed apps, product catalog, pricing, traffic sources, and ad creatives. You visit a store, the tool surfaces the data, and you make faster, cheaper decisions because of it.
The alternative is manual research: opening dozens of tabs each morning, trying to track price changes, guessing whether a product is selling or just sitting. It eats a chunk of every day, and you still miss competitor moves that matter. A dedicated tool compresses that into seconds and runs it against any store you point it at.
Practically, this means you can check a competitor's best-sellers before adding a product to your catalog, confirm which theme converts for a given niche before paying a designer, and see which ad angles a competitor is testing before you write your own copy.
Five ways spy tools move the needle
Each of these replaces a decision you'd otherwise make without real data. The combination adds up fast.
Finding Winning Products
Pull up any Shopify store and see which products are moving. Skip the guesswork and stock what already has proven demand.
Checking Apps and Themes
See the exact theme and apps a competitor runs. Know what's powering their store before you build your own.
Ad Analysis
Find out where a store gets its traffic and browse their active Facebook and Instagram ads. Use that to sharpen your own campaigns.
Tracking Sales
Watch how competitor stores perform over time. Spot their peak selling periods and understand when discounts kick in.
Setting the Right Prices
See what other stores charge for the same or similar products. Price confidently instead of guessing what the market will accept.
Taken together, these five data points replace weeks of trial and error with actual evidence. Every product choice and every ad dollar gets grounded in what already works rather than what might.
Why merchants choose Koala Inspector
Koala Apps has built Shopify research tools since 2018. Today more than 250,000 merchants use Koala Inspector to study competitors and validate products before committing budget.
Koala Inspector works as a Chrome extension, so you're already on the page when you want the data. Open a Shopify store, click the extension, and you see the theme it runs, every app installed, the top-selling products, estimated traffic sources, and active social ads. There's no separate dashboard to visit or CSV to export.
The free plan covers the basics. Premium ($22/month) adds 220 renewing tokens for deeper product research, sales estimates, the full ad library, and advanced store tracking, and you can top up anytime with one-time token packs ($3.99 to $11.99). For a lot of merchants the free tier alone handles day-to-day competitor checks, which is rare among spy tools that gate almost everything behind a subscription.
Questions? The Koala Apps team is reachable directly, and the extension is updated continuously based on what merchants ask for.
