6 best Koala Inspector alternatives in 2026
Koala Inspector is a capable Shopify spy extension — but it is not the right fit for everyone. Here are 6 alternatives compared on price, features and who each one is actually for, including the cases where Koala Inspector is still the one to keep.
The best-known free Shopify spy extension, with 250,000+ users. Click the icon on any Shopify store to get bestsellers by estimated sales, theme and app detection, traffic estimates and live ads — plus two things most rivals lack: AliExpress supplier matching by image, and monitoring that alerts you when a tracked store changes a product or a price.
Why people look for a Koala Inspector alternative
-
Sales data costs $22 a month
Koala’s free tier covers browsing, theme and app detection and never expires — but the numbers most people install it for, the sales and revenue estimates, sit behind the $22/month plan. That is the single most common reason people start looking.
-
It stops at the extension
Koala advertises no searchable store database, no public API and no AI-assistant access. If you want to pull competitor data into a spreadsheet, a script or a Claude conversation, that is a gap — several tools below cover it.
-
Token packs on top of the subscription
Some usage is metered through one-time token packs from $3.99, so a heavy research week can cost more than the headline price suggests.
We build a competing tool, so read this with that in mind — which is exactly why every block below lists what the tool does worse as well as better, and why 4 of the 12 rows in the comparison table go against us.

Free trial, then paid
1. Store Detector
The closest like-for-like swap: the same one-click sidebar on any Shopify store, but the traffic and revenue estimates are in the free tier rather than behind $22/month, and the same data is also reachable as free ranking pages, a JSON API and an MCP server.
What you get
- Free core with no credit limits — the extension, the rankings and the API need no card
- One sidebar covers traffic, revenue, ads, apps, theme, bestsellers and SEO
- Section clone: lift a section from any store as working code
- A public JSON API and an MCP server, so Claude or ChatGPT can query the index directly
- Free ranking pages for every country and niche we hold — open, no login wall
What it does not do
- No ad creative library — we report that a store is advertising and how many ads are live, not the creatives themselves
- No email campaign archive; we detect the email platform, not the sends
- No supplier or AliExpress image matching
- Shopify only — WooCommerce, Amazon and TikTok Shop are out of scope
Pricing
The extension, every ranking page, all 17 free tools and the public JSON API are free with no account. Pro is $4.99/month billed annually ($59.88/year) or $9.99/month billed monthly, charged when you subscribe.
Best for
Anyone who wants the full per-store picture — traffic, ads, apps, theme, SEO — from a free tier with no search credits to run down, and who wants the same index reachable as open ranking pages, a JSON API and an MCP server rather than only through a dashboard.
2. PPSPY
Shopify spy + product research
A Chrome extension and web app built around 15-day AI sales tracking — it predicts a competitor’s orders over time rather than giving you one snapshot. Add product research by sales, revenue, price and category, store filtering by revenue, traffic and region, a store theme tool, an ad tracker, one-product-store discovery, a public API and an AI-assistant integration, over an index of 1M+ stores and 200M+ products.
Why it is on this list: The nearest match if what you actually wanted from Koala was sales numbers — PPSPY’s 15-day tracking gives you a trend for a competitor’s orders instead of one estimate.
Strengths
- 15-day AI sales tracking — a trend line for a competitor’s orders, not a single estimate
- Large index: 1M+ stores and 200M+ products
- Ads and Ad Tracker products alongside the store research
- One-product-store discovery and landing-page research
- A public API and an AI-assistant integration, which most spy extensions lack
Limitations
- A trial rather than a permanently free tier
- Credit- and tracker-metered, so research volume drives the tier you need
- Dropshipping-first: no section clone or on-page CRO checklist
Pricing
$39–$299/mo
Standard $39/month ($328/year), Pro $99/month ($832/year) and Business $299/month ($2,512/year), metered by trackers and monthly credits. Registration gives you a trial with no card required, but there is no permanently free tier.
Visit PPSPYBest for: Dropshippers who want to watch a competitor’s order volume move over a fortnight before committing ad budget to the same product.
3. TrendTrack
Store database + ad & email spy
The most feature-complete of the store-database platforms: 5M+ stores and 250M+ ads, with a shop database you can filter by niche, country and growth, an ad library, a BrandTracker that follows a competitor’s spend and hooks, shop analytics, and an email library that archives the campaigns brands send. It also ships free Shopify app and theme detectors, a free Chrome extension, and an MCP integration for Claude and ChatGPT.
Why it is on this list: A step up in scope: it also ships a Chrome extension and app/theme detectors, and adds an ad library, an email archive and a 5M-store database — for $42/month rather than $22.
Strengths
- Email library — an archive of the campaigns a brand actually sends, which almost nobody else has
- Ad library across 250M+ ads, plus BrandTracker for spend, hooks and landing pages
- 5M+ store database with niche, country and growth filters
- Shopify app and theme detectors, plus a free Chrome extension
- An MCP integration, so Claude or ChatGPT can query stores, ads and emails directly
Limitations
- No permanently free plan — the cheapest ongoing tier is $42/month on annual billing
- Per-seat pricing at $20 on top of the plan
- Result limits (shops, ads, email) are tiered, so the cheapest plan caps how much you can pull
Pricing
$42–$105/mo
Starter $42, Pro $63 and Business $105 per month on annual billing ($50 / $75 / $125 monthly), plus a custom Enterprise tier. 15% off quarterly, 30% off annual, and $20 per extra seat. There is a free Chrome extension and a free signup, but no permanently free plan.
Visit TrendTrackBest for: Agencies and funded DTC teams that need ad creatives and email campaigns archived alongside store data, and have a research budget to match. The email library in particular is something Store Detector does not offer.
4. Dropship.io
Product research + store & ad spy
A product-research platform that has pivoted hard toward TikTok Shop. It combines a product database, sales tracking, a Facebook ad library with an advertiser tracker, a shop library you can filter by revenue and growth, a Magic AI lookalike search by image or video, and a 350,000-creator library. 100,000+ users and 4.8/5 on Trustpilot.
Why it is on this list: Worth a look if your research is drifting toward TikTok Shop, which Koala does not cover at all.
Strengths
- Deep TikTok Shop coverage — revenue, daily sales and growth, where most Shopify tools have none
- Ad library with an advertiser tracker and spend in USD
- Magic AI lookalike search from an image or a video
- A 350,000-creator library for influencer sourcing
- Free Shopify theme detector, and a Chrome extension for ad spend and store analysis
Limitations
- No permanently free plan — a trial, then $26/month at the cheapest on annual billing
- Credit-metered: every Product, Shop, Creator and Ad Library view costs a credit, so heavy research months hit the cap
- Product-research first — thinner than a spy extension on a single store’s app stack and SEO
Pricing
$26–$49/mo
Annual billing is $26, $34 or $49 per month for Basic, Standard and Premium; monthly is $39, $59 or $99. Usage is credit-metered — product, shop and ad library credits, plus caps on tracked shops.
Visit Dropship.ioBest for: Dropshippers whose next product is coming from TikTok Shop rather than Shopify, and who want creator sourcing in the same tool.
5. SellerCenter
Multi-platform spy + sourcing
The broadest surface area in this list: a web app plus two Chrome extensions (ShopifyHunt for stores, AliNiche for AliExpress) covering Shopify, Amazon, Wish, Shopee and Lazada. It adds 15-day sales tracking, ad intelligence across Facebook, TikTok, YouTube and Instagram, and 1688/Taobao image sourcing. 1.4M+ users.
Why it is on this list: Keeps Koala’s AliExpress sourcing idea and widens it — 1688 and Taobao image search, plus Amazon, Wish, Shopee and Lazada.
Strengths
- Covers five marketplaces — Shopify, Amazon, Wish, Shopee and Lazada — not just Shopify
- Ad library across Facebook, TikTok, YouTube and Instagram
- 1688 and Taobao image sourcing, alongside AliExpress
- Shopify theme and app detectors, plus 15-day sales tracking with AI order trends
- A permanently free tier, and paid tiers that start at the same price as ours
Limitations
- Split across a web app and two separate extensions rather than one sidebar
- Breadth over depth — less detailed on a single Shopify store than a focused spy tool
- Credit-metered, with 300-item display limits on most features at the free tier
Pricing
Free · $4.99/mo
A permanently free tier with 1,000 credits a month, then Basic $4.99/month annual ($9.99 monthly), Pro $14.99 ($29.99) and Expert $49.99 ($99.99), metered by monthly credits. The Basic tier is priced identically to Store Detector Pro.
Visit SellerCenterBest for: Sellers researching across Amazon, Wish, Shopee or Lazada as well as Shopify, and sourcing from 1688 or Taobao rather than AliExpress alone.
6. BrandSearch
Store database + ad spy
A brand library of 7.5M+ Shopify stores and 160M+ ads, aimed at teams with real ad spend. Its Spectre AI tracks a competitor’s ads and landing pages daily, swipe files let you keep the creatives you want to model, and there is a free Chrome extension plus an API and MCP integration. Used by 50,000+ marketers including 7- and 8-figure brands.
Why it is on this list: If the panel you used most in Koala was live ads, BrandSearch shows you the creatives themselves rather than a count.
Strengths
- Very large ad index — 160M+ ads with AI-assisted discovery
- Spectre AI tracks competitor ads and landing pages daily, with AI-ready JSON export
- Swipe files for the creatives worth modelling
- Brand library filterable by revenue, traffic and ad activity, across Meta, Google and TikTok
- Free Chrome extension, plus an API and MCP integration
Limitations
- Pricing is not published — you have to start a trial to find out what a tier costs
- No permanently free plan, only a trial
- Ad-first: the store-side detail is thinner than a dedicated Shopify spy tool
Pricing
Free trial, then paid
Three tiers — Starter, Outscaler and Agency — with monthly or yearly billing (roughly three months free on annual). No figures were published on their pricing page when we checked; the tiers are described by limits, from 15K stores on Starter to unlimited above it.
Visit BrandSearchBest for: Media buyers who need to see and save competitors’ actual ad creatives and landing pages every day. Store Detector reports ad activity but does not archive the creatives.

So which one should you pick?
There is no single best Koala Inspector alternative — there is a best one for the job you are doing. Find your row.
You want Koala’s core, without the $22
Store Detector
Same sidebar workflow, traffic and revenue in the free tier, plus rankings, an API and MCP access.
You need AliExpress supplier matching
Koala Inspector
Stay put. Image-based supplier matching is a real Koala capability and Store Detector does not have it.
You want a competitor’s order trend
PPSPY
15-day AI sales tracking is built for exactly that question.
You need ad creatives, not ad counts
BrandSearch or TrendTrack
Both archive the creatives. Store Detector reports ad activity and says so plainly.
Frequently asked questions
Is there a completely free alternative to Koala Inspector?
Store Detector is free with no card and no trial clock: the extension, the traffic and revenue estimates, every ranking page, all 17 free tools and the public JSON API. Koala also has a free tier that never expires, but its sales estimates are on the $22/month plan. SellerCenter runs a permanently free tier too, capped at 1,000 credits a month.
What does Koala Inspector do that Store Detector does not?
Two things, and they are genuine. Koala matches products to AliExpress suppliers by image, and it monitors tracked stores and alerts you on product and price changes. Store Detector has neither — if either is central to your workflow, Koala is the better tool.
Can I use both?
Yes, and plenty of people do. They are both Chrome extensions and they do not conflict. A common pattern is Store Detector for the store read and the rankings, Koala when you need to trace a product back to a supplier.
Does Store Detector estimate sales like Koala does?
It estimates monthly visits and gives a modelled revenue range with a confidence indicator, plus a 12-month traffic trajectory. Both tools are modelling from external signals — neither sees a merchant’s real Shopify dashboard. Our methodology page shows exactly how ours is built.
