What is a Shopify store analyzer? It is a tool that reads what a Shopify storefront already shows the public and organises it into one report. A good one answers four questions about any store you open: which theme it runs, which apps it has installed, what it sells and at what prices, and whether it is paying for ads. Koala Inspector is a free Chrome extension that does all four on any Shopify store you visit, with no login, no store access, and nothing to paste.
That list is deliberately short. Analyzing a competitor is not a research project, and treating it as one is why people give up. One merchant who studies stores for a living put it plainly on r/dropshipping: going through a store top to bottom was "eating 30-40 minutes per store" and still produced nothing useful, until they cut it down to a fixed handful of checks. Narrowing the questions is what turns two stores an afternoon into fifteen.
How to analyze a Shopify store, step by step
Run the four checks in this order every time. Each one narrows what the next one means, and the whole pass takes about four minutes.
1. Identify the theme
The theme is the foundation everything else sits on, so it goes first. Koala Inspector shows the active theme name on its first screen, with a link straight through to that theme in the Shopify theme store. Theme detection is free and costs no tokens.
What it tells you. A store on a free Shopify base theme is spending its money elsewhere, usually on ads or product. A store on a premium conversion theme has decided the storefront itself is the lever. And a heavily customised build tells you there is a developer on the payroll, which changes how realistic it is to copy them.
How to act on it. If a competitor's storefront converts and you are still choosing, start from their theme rather than from a gallery. You get the same section layout, the same mobile behaviour and the same speed profile on day one. Our free Shopify theme detector does this check without installing anything if you only need the name.
Across the Shopify stores Koala tracks, theme choice clusters hard around a handful of names:
Trademark leads with 886 stores, then Dawn at 755, Horizon at 404, Impulse at 292, Rise at 236 and Savor at 233. Those counts cover the stores Koala tracks rather than all of Shopify, so read them as what active stores keep choosing, not as a global census. The useful takeaway is that the field is narrow: your competitor is probably on one of ten themes, and you can have the same one this afternoon.
2. Read the app stack
Apps are the closest thing to a public statement of strategy a store makes. Koala Inspector lists every app the store has installed and groups them by job, with a link out to each one's Shopify App Store listing. App detection is free too.
What it tells you. Where the money and attention go. A store with a review app, an email and SMS app and a bundle builder has decided its growth comes from social proof, owned audience and average order value, in that order. A store with a page builder is testing landing pages. A store with a currency converter and a tracking app is selling internationally and expects the shipping questions.
How to act on it. Copy the categories before you copy the tools. Across the stores Koala tracks, the same jobs come up again and again:
| App | Stores running it |
|---|---|
| Judge.me Product Reviews | 2,396 |
| Klaviyo: Email Marketing & SMS | 1,872 |
| Shopify Inbox | 1,028 |
| Klarna On-Site Messaging | 1,018 |
| PageFly Landing Page Builder | 849 |
Reviews and email sit at the top by a wide margin. If a store you are studying skips both, it is leaving the two cheapest conversion levers untouched, and that is as useful a finding as anything it does run. Our free Shopify app detector runs the same check from a pasted URL.
3. Pull the catalogue and the price points
Now open the products view. You get the full catalogue, the likely best-sellers, the total product count, the price range from low to high, and the date the first product was published. Sort by date added to see what the store has been pushing lately, and favourite anything you want to check again next month. All of it is free, and you can export the list to CSV for 1 token.
What it tells you. The offer, and the margin they are chasing. A twelve-product store with one item at four times the price of the rest is a hero-product operation, and that one product is carrying everything. A 900-product catalogue with a flat price band is a volume play living on ad efficiency. Price range plus product count tells you which game you have walked into before you read a single product page.
How to act on it. Pull their price ladder and put it next to yours. If they anchor at $89 and you anchor at $39, you are not competing on the same shopper. Then run the arithmetic: our free Shopify revenue calculator multiplies traffic by conversion rate by average order value, so you can size the store from its own numbers rather than guessing.
4. Check what ads it is running
Last, look at what the store is paying to say. The Ad Campaigns view splits into Google and Facebook or Instagram, and each campaign card carries the URL, title, description and tags. It costs 2 tokens, so a free plan covers about seven ad checks a month.
What it tells you. Their tested messaging, handed to you. Ad copy is the one part of a competitor's marketing that has been through real money and real feedback. The angle they lead with is the angle that worked, and the offer in the ad is the offer they are willing to pay to promote.
How to act on it. Note the hook and the offer, then check whether the landing page matches. A store running a heavy discount in its ads while its site shows full price is testing a segment, and that gap is where you can undercut. In Koala's own ad-activity data the busiest advertisers are running dozens of Facebook creatives at once, so what you see is a portfolio of tests rather than one message.
Finish by adding the store to tracking if it is worth following. Shop Tracking costs 15 tokens per store and logs apps added or removed, theme swaps, new and dropped products, price changes and variant changes across more than ten event types. It is the one feature the free plan does not include; Premium covers up to 50 stores. This is the check that catches the thing you cannot catch by looking twice a year: one merchant spent three weeks debugging ads and copy before finding out a competitor had cut prices 22% the whole time.
Three questions people ask a store analyzer
Most searches that land here are really one of three specific jobs. Each has a short answer and a tool page that does only that job.
How do I check what theme a Shopify store is using? Open the store and click Koala Inspector; the theme name is on the first screen with a link to install it. It handles customised and renamed themes, and the two it cannot name are a fully bespoke build and a headless storefront, because neither is based on a standard Shopify theme. No install needed? Use the Shopify theme detector.
How do I see what apps a Shopify store uses? The Apps screen lists every installed app, grouped by type, with a "Get App" link to each listing. It is free and unlimited. From a pasted URL instead, use the Shopify app detector.
How do I estimate a Shopify store's sales? No outside tool reports exact sales, because only the owner sees the real dashboard. Koala Inspector gives you an estimated traffic and sales read modeled from public signals any visitor's browser can already see, sampled over time. Treat it as a range and a direction rather than a figure: a store reading around $40k a month is a $30k to $60k store, and three reads across three weeks tell you far more than one. To do the arithmetic yourself, use the Shopify revenue calculator, or see the full method on our Shopify sales tracker page.
What a store analyzer cannot tell you
Honesty here saves you from bad decisions later.
It cannot see inside the admin. Orders, customers, real revenue, ad spend and margin all live behind a login, and no browser tool reaches them. Sales and traffic figures are modeled estimates, useful for comparing two stores and for spotting a trend, and useless as accounting.
It cannot read a store that is not on Shopify. Open the extension on a WooCommerce or BigCommerce site and it says so rather than guessing.
It cannot name a fully bespoke theme, because there is no standard theme underneath to recognise.
And it cannot tell you whether a competitor is profitable. A store can look enormous and still be losing money on every order. What the analysis gives you is the shape of their operation: what they sell, at what price, on what foundation, with what tools, and what they are paying to say. That is enough to decide who is worth copying.
