Your competitor's Shopify store is doing something right. They are running apps you have never heard of, using a theme that converts, and selling products you did not know were trending.

You could guess what they are doing. Or you could look.

Spying on Shopify stores is standard practice in e-commerce. Every serious dropshipper and brand operator studies their competitors. The question is whether you pay $22/month for the privilege or use free tools that cover most of what you need.

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 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:

1. /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.
2. /collections/all — Browse all products organized by collection.
3. View page source — Search for Shopify.theme to identify the theme, look for known app script patterns (e.g., loox, judgeme, klaviyo).
4. 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.

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.

Bottom Line

You do not need to pay $22/month to spy on Shopify stores in 2026. Free tools cover the essentials — app detection, store classification, product browsing — and AliShopping Tools does it with no monthly limits.

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.

The best competitive intelligence tool is the one you actually use. If cost is the barrier, remove it.
