The best ecommerce data providers, compared honestly
By the OpenData team · 15 Nov 2026
The honest short answer: the best ecommerce data provider depends on whether you need a store list, a technology lookup, or sales contacts — and the pricing models differ more than the data does. OpenData charges per row, from $4.00 per 1,000 full records and no subscriptions; Store Leads, BuiltWith and Wappalyzer charge $75–$295 a month (vendor-reported, checked 2026-11-15).

First, separate the three categories
Providers get compared as if they were interchangeable, but they sell different things. Store databases (OpenData, Store Leads) sell lists of operating online stores with filters like platform, country and technology. Technology lookup tools (BuiltWith, Wappalyzer) identify what a given website runs and build prospecting around that. B2B contact databases — Apollo is the best-known example — sell people: names, job titles and contact details at companies. That is a different category with different data, and it is not scored in this comparison.
If your job is to get the stores in this niche, in this country, on this platform, you want a store database. If your job is to find every site using one particular technology, a lookup tool fits better. Buying the wrong category is the most common way this spend gets wasted.
OpenData — pay-per-row store data
OpenData lists 1,504,744 verified ecommerce stores across 1,554,041 tracked domains (snapshot 15 Nov 2026). Verified means each storefront was fetched and at least one ecommerce technology was detected; every record carries its source URL and last-observed date. 205,297 stores include a public business email and 111,859 a store-published business phone. The Shopify list alone holds 269,688 verified stores.
Pricing is per row only, with no subscriptions and no fixed packages: full records with public contacts cost $4.00 per 1,000 rows, dropping $0.50 per volume step to $2.00 per 1,000 above 500,000 rows, and platform- or technology-only records without contacts cost $1.00 per 1,000 rows. Checkout is by PayPal, the export starts right after payment, and the index behind every pull is refreshed monthly. The free test is the strongest part: a store checker with 30 full-record unlocks a month and a free sample file per industry.
Store Leads — subscription store database
Store Leads is the closest direct alternative: a store database aimed at people selling to ecommerce businesses. Its vendor-reported figures (checked 2026-11-15) are $75 a month for search-only access, exports from $250 a month, and a claimed 14M+ stores. The claimed count is far larger than OpenData's verified count, but the counting methods differ — OpenData counts a store only after fetching its storefront and detecting ecommerce technology on it — so compare the definitions before comparing the numbers.
Choose Store Leads if you prefer a subscription with continuous in-app searching and its larger claimed index, and the monthly cost fits an ongoing prospecting workflow rather than a one-off project.
BuiltWith — technology lookup at scale
BuiltWith is primarily a technology-profiling service: it tracks what websites are built with and sells that intelligence for prospecting and market analysis. Basic starts at $295 a month (vendor-reported, checked 2026-11-15). It is the deepest of the four for raw technology coverage across the whole web, but it is not packaged as ready-made store lists — expect to do more filtering work yourself, and expect a general-web index rather than a store-only one.
Wappalyzer — tech lookup with familiar tooling
Wappalyzer identifies the technologies on individual websites and sells data access for lead generation; Pro is $250 a month (vendor-reported, checked 2026-11-15). Its browser tooling is the most convenient of the four for checking a handful of sites by hand. Like BuiltWith, it starts from technology detection across the web at large, so building a clean, store-only list takes additional filtering.
The comparison, and how to test each one
The full side-by-side — what each provider is for, starting price, export model, database size claims and free tests — is in the comparison table, and the store counts behind OpenData's side of it are published in the reports. Whatever you choose, run the free test first: check a set of stores you already know against each provider and see whose records match reality. OpenData's checker answers with full records, not teasers, for the first 30 unlocks each month.
- Need store data once, for one project: paying per row beats a subscription you must remember to cancel.
- Need continuous prospecting every week: a subscription's in-app search may justify its monthly cost.
- Need technology coverage beyond ecommerce: a general lookup tool covers more of the web.
- Need named people at companies: that is the B2B contact-database category — none of these four is that.
Decision guide by use case
For dropshipping and niche research, market sizing, or a one-off outreach campaign to stores, OpenData's per-row rates are the cheapest serious option — $4.00 per 1,000 full records against $75–$295 a month (vendor-reported, checked 2026-11-15). For an agency running always-on prospecting into ecommerce, Store Leads' subscription model matches that rhythm. For technology market analysis across the whole web, BuiltWith is the specialist; for quick manual tech checks plus data access, Wappalyzer. Current OpenData prices are on the pricing page.
Questions, answered straight
What is the cheapest ecommerce data provider here?
OpenData, for one-off use: you pay per row — full records with public contacts cost $4.00 per 1,000 rows, with no subscription. The alternatives are subscriptions — Store Leads from $75 a month, Wappalyzer Pro at $250 a month and BuiltWith Basic at $295 a month (vendor-reported, checked 2026-11-15). If you prospect every week, a subscription can still be better value; if you need a list once, it usually is not.
Which provider has the biggest database?
By vendor-reported claims, Store Leads reports 14M+ stores (checked 2026-11-15). OpenData lists 1,504,744 verified stores, where verified means the storefront was fetched and ecommerce technology detected on it. The counting definitions differ, so the honest comparison is to test both against stores you already know.
Is OpenData a subscription?
No. OpenData charges per row only — search and filtering are free with contacts masked, and a paid pull exports CSV plus a formatted Excel file, fingerprinted per buyer under a no-redistribution licence. The index is refreshed monthly, and pulling a later refresh is a new purchase decision, not an automatic charge.
Are Apollo-style B2B contact databases an alternative?
They solve a different problem. Apollo-style databases sell named people — job titles and contact details at companies. Store databases sell operating stores with platform, technology and public business contact data. If you need stores, a contact database is the wrong tool, and the reverse is also true.
How can I test these providers before paying?
OpenData offers a free store checker with 30 full-record unlocks a month and one free sample file per industry, so you can inspect real records first. The lookup tools offer their own limited lookups. The most reliable test is to run stores you already know through each one and compare what comes back.
