6 best SellerCenter alternatives in 2026

SellerCenter is a capable multi-marketplace research suite — 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 SellerCenter is still the one to keep.

SellerCenter Multi-platform spy + sourcing sellercenter.io

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 people look for a SellerCenter alternative

Three products, not one

The workflow is split across a web app and two separate Chrome extensions — ShopifyHunt for stores and AliNiche for AliExpress. That is three surfaces to learn and keep installed.
Breadth over depth on Shopify

Covering Shopify, Amazon, Wish, Shopee and Lazada means no single one gets the depth a focused tool gives it. If you only sell on Shopify, most of that surface area is not for you.
Credits, not seats

Every tier is metered by monthly credits — 1,000 on the free plan — and most features cap the display at 300 items. The bill tracks how much you look, not what you are trying to answer.

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.

#1 · Best free all-rounder for Shopify Shopify spy extension + free rankings

1. Store Detector

One extension, one sidebar, Shopify done properly — traffic, revenue, ads, apps, theme, section clone, bestsellers and SEO, with no credit meter on lookups. Note the prices match: SellerCenter Basic and Store Detector Pro are both $4.99/month annual. No multi-marketplace coverage and no supplier sourcing here, so it is a narrowing rather than a widening.

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.

Best for supplier matching

2. Koala Inspector

Shopify spy extension

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 it is on this list: Keeps the AliExpress sourcing in a single extension with a free tier.

Strengths

AliExpress supplier matching by image — find who actually makes the product
Store monitoring with alerts on product and price changes
A free tier that never expires for theme and app detection
CSV and Excel export

Limitations

Sales estimates sit behind the $22/month tier — over four times Store Detector Pro
Some usage is metered through one-time token packs on top of the subscription
No searchable store database, public API or AI-assistant access is advertised
No section clone or on-page SEO/CRO checklist

Pricing

Free · $22/mo

A free tier that never expires covers browsing, theme and app detection. Sales estimates and the advanced panels are $22/month, with one-time token packs from $3.99.

Visit Koala Inspector

Best for: Dropshippers who want to trace a product back to its AliExpress supplier and be alerted when a competitor changes a price. That supplier match is a real capability Store Detector does not have.

Best for sales tracking

3. 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: Shopify-focused product research with 15-day sales tracking.

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 PPSPY

Best for: Dropshippers who want to watch a competitor’s order volume move over a fortnight before committing ad budget to the same product.

Best for TikTok Shop research

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: Published pricing, an ad library, and TikTok Shop instead of Wish and Shopee.

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.io

Best for: Dropshippers whose next product is coming from TikTok Shop rather than Shopify, and who want creator sourcing in the same tool.

Best all-in-one, if the budget is there

5. 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: If you want one deep platform rather than five shallow ones, with ads and email archived.

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 TrendTrack

Best 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.

Best for B2B lead generation

6. StoreLeads

Ecommerce store database (B2B)

Not a dropshipping spy tool — a data platform for prospecting and market research. 13.7M+ stores across 408 platforms (2.9M of them Shopify), 40+ attributes per store, 60 search filters, CRM enrichment into HubSpot, Salesforce, Outreach and Pipedrive, an API, and historical app install and uninstall timelines. Bought mostly by agencies, Shopify app developers and equity funds.

Why it is on this list: The multi-platform answer done at data scale — 408 platforms, 13.7M stores, with an API.

Strengths

By far the largest index — 13.7M active stores across 408 platforms, and 1.7B products
Historical app install and uninstall timelines, which nothing else here offers
Theme, theme vendor and theme style tracked alongside apps and third-party tech
CRM enrichment straight into HubSpot, Salesforce, Outreach and Pipedrive
A mature API built for bulk export, plus 60 search filters

Limitations

Starts at $75/month and runs to $950 — priced for sales teams, not merchants
The free account is a limited preview, not a working free tier
Built for prospecting, not for judging whether a product is worth selling
No ad or creative intelligence is advertised

Pricing

$75–$950/mo

Premium $75, Pro $250, Elite $450 and Enterprise $950 per month. A free account gives a limited preview; API access starts at the Pro tier.

Visit StoreLeads

Best for: Agencies and Shopify app developers who need lead lists, firmographics and CRM enrichment. If your job is selling to merchants rather than competing with them, this is the right tool and Store Detector is not.

Built from each vendor’s own public marketing, checked 2026-08-02. “Not advertised” means the capability is not claimed on their site — not that it is missing. Prices drift; check the vendor before you buy.

So which one should you pick?

There is no single best SellerCenter alternative — there is a best one for the job you are doing. Find your row.

You only sell on Shopify

Store Detector

Goes deeper on Shopify than a five-marketplace tool can, and does not meter your lookups. Same $4.99 if you upgrade.

You research across marketplaces

SellerCenter

Stay. Amazon, Wish, Shopee and Lazada in one place is genuinely its own thing.

You need 1688 or Taobao sourcing

SellerCenter

No Shopify-focused tool on this page does image sourcing from 1688 or Taobao.

You want platform coverage as data, not a UI

StoreLeads

408 platforms with an API and CRM enrichment — from $75/month.

Frequently asked questions

What is the best SellerCenter alternative for Shopify only?

Store Detector. It is Shopify-only by design, which is why it can go deeper per store — section clone, SEO/CRO checks and an app stack read — and it is free.

Does Store Detector cover Amazon or Wish?

No. The index is Shopify. If cross-marketplace coverage is the reason you use SellerCenter, none of the Shopify-focused tools here replace it — StoreLeads is the closest at the data layer, covering 408 platforms.

Which alternative includes supplier sourcing?

Koala Inspector matches products to AliExpress suppliers by image. Store Detector does not do supplier sourcing at all.
