Koala Inspector offers a free tier with 15 tokens per month (1 token per store analysis).
Their premium plan increased from $9.99 to $22/month in 2026 — a 120% price hike.
For unlimited free Shopify spy, AliShopping Tools offers app detection, store classification, and product catalog browsing with no monthly limits.
2
Can I spy on any Shopify store for free?
Yes.
Most Shopify stores expose their tech stack and product data publicly.
Free extensions like AliShopping Tools detect 200+ installed apps, classify the store type, and let you browse the product catalog — all without signup or token limits.
You can also manually check /products.json and view page source on any Shopify store.

What is the best free Shopify spy tool in 2026?
For app detection and store classification: AliShopping Tools (unlimited, free, 200+ apps detected).
For deeper analytics like traffic estimation and product history tracking: Koala Inspector (15 free lookups/month, $22/month for unlimited).
For general tech stack detection: BuiltWith or Wappalyzer (free tiers available).
Most dropshippers can cover their needs with AliShopping alone.
4
How do Shopify spy tools detect which apps a store uses?
Shopify apps leave fingerprints in a store's page source — JavaScript files, meta tags, and DOM elements with recognizable patterns.
Spy tools scan for these known patterns and match them against a database of Shopify apps.
For example, Loox adds specific script tags, Klaviyo injects tracking code, and Judge.me creates identifiable review widgets.
Extensions automate this detection across hundreds of patterns instantly.
5
Is it legal to spy on Shopify competitor stores?
Yes.
Shopify spy tools analyze publicly available information — page source code, product catalogs, and technology fingerprints that any visitor can see.
This is standard competitive intelligence, no different from visiting a competitor's physical store to observe their layout and pricing.
No private data, login credentials, or protected systems are accessed.
6
Koala Inspector used to be my go-to. Is AliShopping a real replacement?
For app detection, store classification, and product catalog browsing — yes, AliShopping covers those at zero cost with no lookup limits.
Where Koala Inspector still has the edge (on its paid tier) is historical traffic estimates and revenue projections.
If your main use case is 'what apps does this store run and is it a dropshipper or a brand,' AliShopping covers it without the $22/month.
7
What can free Shopify spy tools not do?
Free tools cannot estimate traffic volume, monthly visitors, or revenue — those require paid subscriptions and accuracy varies significantly.
They also lack historical product tracking (you see current state, not trends) and cannot access private store data like conversion rates or ad spend.
Treat free tools as a starting point for competitor research, not a complete analytics suite.
8
Is there a free Shopify spy tool with no usage limits?
Yes.
AliShopping Tools offers unlimited free Shopify store analysis — 200+ app detection, store classification (brand vs. dropshipper vs. hybrid), and product catalog browsing.
No tokens, no monthly caps, no signup required.
Koala Inspector's free tier limits you to 15 lookups per month; AliShopping has no such restriction.
Best Free Shopify Spy Tools in 2026: Analyze Competitor Stores Without Paying
Quick answer: AliShopping Tools gives you unlimited free Shopify store analysis — 200+ app detection, store classification, and product catalog browsing. Koala Inspector raised prices from $9.99 to $22/month in 2026; its free tier caps you at 15 lookups/month. For zero-budget competitor research, AliShopping covers app detection and store analysis. For deeper analytics (traffic, revenue estimates), you will need to pay. Install AliShopping Tools free →
Something is working for your competitor. Their store traffic is up, their product lineup changed recently, and you have no clear picture of what they are running. You could spend a week guessing — or you could look at what is actually installed, what products they added last month, and what apps they are using to convert visitors.
Shopify stores expose more than most operators realize, and the tools to read that data have gotten significantly better (and cheaper) in the past year. This guide compares the best free Shopify spy tools available in 2026, explains what each one actually does (and does not do), and helps you decide when free is enough — and when it is worth paying.
What happened: A dropshipper was trying to understand why a competitor store in the pet accessories niche was converting better than his own. He ran the competitor's URL through a free app detection tool and found they were running a review app, an upsell widget, and a currency converter — none of which he had installed. He added the currency converter that week (the most straightforward fix), and within two weeks saw a measurable drop in cart abandonment from his European visitors. He did not need traffic estimates or revenue projections — just the app list.

What Shopify Spy Tools Actually Do
Before comparing tools, understand what "spying" on a Shopify store means in practice. These tools analyze publicly available information — they do not hack into anything or access private data.
App detection. Shopify apps leave fingerprints in a store's page source — JavaScript files, meta tags, DOM elements. Spy tools scan for these patterns and tell you which apps a store is running. If every successful store in your niche uses Loox for reviews and ReConvert for upsells, that is actionable intelligence.
Store classification. Is this store a brand, a dropshipper, or a hybrid? Classification tools look at product sourcing patterns, shipping origins, and catalog structure to make this determination.
Product catalog analysis. Most Shopify stores expose their product catalog through /products.json and collection pages. Spy tools present this data in a browsable format — prices, launch dates, variant counts.
Tech stack identification. Beyond Shopify apps, tools can detect the theme, payment processors, analytics tools, and marketing pixels a store uses.
Traffic and revenue estimation (paid only). Some tools estimate a store's traffic volume and revenue. These require paid subscriptions and the accuracy varies significantly — treat estimates as directional, not precise.
Free Tools Compared
AliShopping Tools — Unlimited Free Spy
AliShopping is primarily known as an AliExpress product research extension, but it includes a full Shopify spy module that works on any Shopify-powered website.
What you get for free (no limits):
200+ app detection. The extension scans page source for known Shopify app fingerprints and reports which apps are installed. This covers review apps (Loox, Judge.me, Stamped), upsell tools (ReConvert, Bold), analytics (Lucky Orange, Hotjar), marketing (Klaviyo, Omnisend), and more.
Store classification. Identifies whether a store operates as a brand, dropshipper, or hybrid based on observable signals — product sourcing patterns, shipping information, and catalog structure.
Product catalog browsing. View the store's full product list with pricing and basic product data.
Live sales tracking. See real-time purchase activity on Shopify stores, updated every 30 seconds.
What AliShopping does not have:
No traffic estimation or monthly visitor counts.
No revenue or sales volume projections.
No historical product tracking over time (you see current state, not trends).
No competitor comparison dashboards across multiple stores.
How it works: Install the Chrome extension, visit any Shopify store, and a toolbar appears at the bottom of the page automatically. No signup, no account, no tokens, no monthly limits.
Koala Inspector — The Established Player (Now $22/Month)
Koala Inspector has been the dominant Shopify spy tool for years, with 250,000+ Chrome Web Store users. In early 2026, they raised pricing from $9.99/month to $22/month — a 120% increase that sent many users searching for alternatives.
Free tier (15 tokens/month):
Each store analysis costs 1 token.
15 lookups per month is enough for occasional checks but not for systematic competitor research.
Core features available: app detection, theme identification, basic store data.
Paid tier ($22/month):
Unlimited lookups.
Deeper Shopify-specific analytics.
Product tracking and historical data.
Traffic estimation (accuracy varies).
Best-selling product identification.
Honest assessment: Koala Inspector has more Shopify-specific depth than AliShopping on several features. Their best-seller detection, product tracking over time, and traffic estimation are capabilities that AliShopping does not offer. If you are a full-time dropshipper doing daily competitor analysis across dozens of stores, Koala's depth may justify the $22/month.
But if your primary need is "what apps does this store use?" and "is this a dropshipper or a brand?" — AliShopping covers that completely, with no token limits and no monthly fee.
BuiltWith (Free Tier)
BuiltWith is a general technology profiler, not Shopify-specific. It detects the tech stack of any website — CMS, hosting, analytics, advertising tools, payment systems.
What it does well: Broad tech stack identification. Useful for understanding the full technology picture beyond just Shopify apps.
What it lacks for Shopify spy use: No Shopify app-specific detection depth, no store classification, no product catalog analysis. It will tell you a store runs Shopify and uses Google Analytics, but it will not tell you they use Loox for reviews with a specific review display widget.
Best for: Supplementing a Shopify-specific tool with broader tech context.
Wappalyzer (Free Tier)
Similar to BuiltWith — a general web technology identifier. Detects CMS, frameworks, analytics, and marketing tools.
Free tier: 50 lookups/month.
Same limitations as BuiltWith: General tech detection, not optimized for Shopify-specific intelligence. Will not classify stores, detect Shopify apps by name, or analyze product catalogs.
Manual Methods (No Tool Required)
You can spy on Shopify stores without any extension at all:
/products.json — Append this to any Shopify store URL to see their full product catalog in JSON format. Shows product names, prices, variants, images, and creation dates.
/collections/all — Browse all products organized by collection.
View page source — Search for Shopify.theme to identify the theme, look for known app script patterns (e.g., loox, judgeme, klaviyo).
Check /robots.txt — Reveals some structural information about the store's URL setup.
Limitation: Manual methods are time-consuming and require you to know what to look for. Extensions automate this detection across hundreds of known patterns instantly.

When Free Is Enough (and When It Is Not)
Free tools cover your needs if:
You are researching competitors occasionally — checking what apps successful stores in your niche use before building your own store.
You want to classify stores quickly — is this a brand, dropshipper, or hybrid?
You need app stack intelligence — which review app, which upsell tool, which email marketing platform.
You are on a budget and cannot justify $22/month on a spy tool before your store generates revenue.
You should consider paid tools if:
You do competitor research daily across dozens of stores and need tracking over time.
You need traffic and revenue estimates to size market opportunities.
You want best-seller detection to identify which products drive the most revenue for a competitor.
You are an established store operator where the cost of $22/month is negligible compared to the intelligence value.
Is There a Free Shopify Spy Tool Alternative?
If you have been using Koala Inspector as your primary Shopify spy tool, the 2026 price increase from $9.99 to $22/month may have you looking for a free alternative. The good news: a free Shopify spy tool with no usage caps does exist.
AliShopping Tools offers a complete Shopify spy module at zero cost — no tokens, no monthly limits, no signup required. The extension detects 200+ Shopify apps, classifies stores as brand, dropshipper, or hybrid, and lets you browse the full product catalog with pricing data. For the core spy workflow that most dropshippers need daily — "what apps does this store run, what do they sell, and what kind of operation is this?" — AliShopping covers it completely without any paywall.
Koala Inspector still offers capabilities that AliShopping does not: traffic estimation, revenue projections, best-seller identification, and historical product tracking over time. These are genuinely useful features for power users doing deep competitive analysis. But they sit behind the $22/month paid tier. The free Koala tier (15 lookups/month) is too limited for systematic research.
The practical free Shopify spy tool strategy: install AliShopping Tools for unlimited daily competitor checks (app detection, store classification, product browsing), and reserve Koala's 15 free monthly tokens for the specific stores where you need traffic estimates or historical data. This combination gives you broad coverage at zero cost and targeted depth when it matters.
The Koala Inspector Price Hike: What It Means for You
Koala Inspector's move from $9.99 to $22/month reflects a common pattern in Chrome extension monetization — build a user base with affordable pricing, then raise prices once users are locked in.
For users who relied on Koala's free tier (previously more generous), the 15-token monthly limit makes systematic research impractical. You can check a handful of stores per month, but building a competitive intelligence habit requires more than that.
This is why free alternatives matter. AliShopping's Shopify spy module does not have Koala's full depth on features like traffic estimation and product history tracking. But for the core spy workflow — "what apps does this store use, what do they sell, and is it a real brand or a dropshipper?" — AliShopping delivers that with zero limits and zero cost.
The practical approach for most dropshippers: use AliShopping for unlimited day-to-day competitor checks, and save Koala's 15 free tokens for the stores where you specifically need deeper analytics.

Koala Inspector remains the deeper tool for traffic estimation, revenue projections, and product history tracking. If those features drive your business decisions, the paid tier may be worth it. For everyone else, AliShopping's free Shopify spy covers what you actually need.
