Free and paid alternatives to the Koala Inspector extension, for bulk research, traffic and revenue, and no-install workflows.
Koala Inspector is a Chrome extension that inspects one Shopify store at a time. If you want web-based access, bulk research, or traffic and revenue estimates, SalesTracker and the tools below cover those gaps.
Koala Inspector is handy for a quick look at the store in front of you, but it is built around three constraints: it is a browser extension you have to install, it works on one store at a time as you browse, and it surfaces on-page details rather than estimated traffic and revenue. The alternatives below are grouped by which of those limits they solve.
| Koala Inspector | SalesTracker | |
|---|---|---|
| Access | Browser extension (install required) | Web-based, paste any URL, no install |
| Scope | One store at a time, as you browse | Any domain + a 550K-store directory & leaderboards |
| Data | On-page store details | Adds estimated traffic & revenue |
| Sign-up | Account / extension needed | No signup for the core free checks |
Live example: as of Jun 2026, the highest-traffic store in our dataset is headphonezone.in (~2,982,229 monthly visits). The 550K+ figure reflects AI-powered analysis of multiple public sources. Traffic and revenue are directional estimates, not exact totals.
| Tool | Why switch from Koala | Pricing |
|---|---|---|
| SalesTracker | No extension; bulk + traffic/revenue | Free core; paid revenue depth |
| PPSPY | Adds product & sales research | Freemium |
| Commerce Inspector (Shine) | Deeper SKU-level detail | Paid (premium) |
| ShopHunter | Tracks sales over time | Paid |
| Dropship.io | Dropshipping product hunts | Paid |
| BuiltWith | Multi-platform tech lookups | Free + Paid (enterprise) |
Koala runs as a browser extension on one store at a time and focuses on on-page details. SalesTracker is web-based, paste any domain, no install, and adds the two things an extension can't: estimated traffic and revenue, and a searchable directory of 550K+ Shopify stores. Best when you want to research many stores, not inspect one.
Where Koala shows you what one store has on a page, PPSPY leans into product discovery and store sales estimates, useful if your goal is finding products to sell, not just inspecting a storefront. Freemium, popular with dropshippers.
A step up in depth from an on-page extension view: also offered as Shine, it focuses on SKU-level data across a large set of stores. A fit when Koala's quick snapshot is not granular enough for merchandising research.
Koala gives a one-off snapshot of the store you are viewing; ShopHunter is built to monitor store sales continuously. Choose it when you need an ongoing trend rather than a single point-in-time check.
Pairs product research with store tracking in one workflow, aimed at dropshippers hunting winning products, a broader job than Koala's single-store inspection.
Koala is Shopify-only; BuiltWith profiles technology across any platform, with limited free lookups. Reach for it when you need a broad tech-stack view rather than Shopify-specific sales signals.
Pricing and free-tier availability change often, confirm current details with each vendor.
Start with the Shopify Traffic Checker to size up any store, the App Detector to see its stack without an extension, or browse the Shopify stores directory. For the full landscape, see our best Shopify spy tools comparison.
Koala Inspector is a browser extension used to inspect individual Shopify stores while you browse them. It is a popular, convenient way to look up a single store on the fly, which is also why people seek alternatives that work differently, such as web-based tools that check any domain without an extension or research many stores at once.
SalesTracker is a strong free alternative for a different workflow: its traffic checker and store, theme, and app detectors run in the browser with no extension and no signup for the core checks, and it covers 550K+ Shopify stores, useful when you want to research many stores rather than inspect one at a time.
Common reasons map to Koala's design: it is a browser extension (some want a web tool), it inspects one store at a time (some want bulk research or a directory), and it shows on-page details rather than estimated traffic and revenue. The right alternative depends on which of these limits matters most for your workflow.
Yes. Web-based tools like SalesTracker let you paste a domain and get results without installing anything, which is convenient for repeated or bulk research and works on any device. Extension-based tools like Koala are handy for inspecting a single store as you browse, but require the extension and a visit to each store.
Traffic and revenue numbers from any Shopify research tool are estimates derived from public data, so treat them as directional indicators of scale rather than exact figures. Cross-checking a store across traffic, apps, and theme gives a more reliable picture than any single metric.
