Websites by Technology - BuiltWith Alternative & Store Leads

What does Websites by Technology do?

Pick a technology and countries, get a list of matching websites (domain, title, full tech stack with evidence, popularity bucket, e-mail provider): $5.00 per 1,000 websites found ($0.005 each, shown on the Pricing tab). Websites that do not match, cannot be read, duplicates and invalid inputs are free, and so is a run that finds nothing; no start fee. Data: Google's public Chrome UX Report top lists (monthly; check dataRelease in each run's results for the list month) for the candidates, and each home page read live at run time for the technologies. Jump to How to use it.

It builds lead lists of websites that use a technology, in the countries you choose: "Shopify stores popular in Germany", "WordPress sites in Taiwan's top 10,000", "companies in the US top 10,000 that use HubSpot".

• 🌍 Candidates from real traffic: the Chrome UX Report top lists (Google, CC BY 4.0) rank the most visited websites of 238 countries and worldwide in buckets (Top 1K, 5K, 10K, 50K, 100K, 500K, 1M). You pick the countries and how deep to go.
• 🔍 Live detection, not a stale database: every candidate's home page is read now and checked against about 480 technology fingerprints (CMS, e-commerce platforms, analytics, marketing automation, chat, payments, reviews, consent tools ...). Each match comes with its evidence (the header, cookie or script that proves it).
• 📧 E-mail provider and DNS tools from public DNS records (Google Workspace, Microsoft 365, Zoho ...).
• 📈 Optional enrichment at no extra cost: authority score (0-100) and referring domains, global traffic rank and 12-month trend.
• 💸 You pay only for matching websites. Scanning non-matching, unreadable and duplicate websites is free.

Real results (3 October 2026)

Use cases

• Sell to e-commerce stores: apps, agencies, payment, logistics and marketing tools find Shopify, WooCommerce, Magento or Shopware stores in their markets.
• Competitive displacement: list the sites that use a competitor's product (e.g. Klaviyo, Intercom, OneTrust) and pitch a switch.
• Agency prospecting: WordPress, Wix or Squarespace sites in a country, ranked by real traffic.
• Market share snapshots: SUMMARY.topTechnologiesSeen counts the technologies on every readable website scanned (e.g. how many of Taiwan's top 500 sites use Google Analytics).
• Top-sites lists with tech profiles: leave Technologies empty to get every readable site of a country's top list with its full stack.

How much does it cost?

Event	Price	When
Website found	$5.00 / 1,000 websites ($0.005 each)	a website that matches your technologies is returned

Free: every website scanned that does not match, websites that cannot be read (down, blocked, parked, robots.txt disallows our crawler, adult sites skipped), duplicates and invalid inputs. No start fee. Larger Apify plans get the usual volume discount (Silver 10%, Gold and above 20%).

Example: 200 Shopify stores in one country cost at most $1.00, however many websites have to be scanned to find them.

For comparison (Apify Store; prices as listed on 3 October 2026, users in the last 30 days on 8 October 2026): clearpath/shopify-store-leads (200 users) $0.006 per lead; apivault_labs/website-leads-database (135 users) $0.008 per row; ecommerce_leads/store-leads-14m (111 users) $0.006; builtwith/builtwith-official-technology-scraper (120 users) $0.002 per row; igolaizola/shopify-store-finder (52 users) $0.005 per row + $0.005 per start; aitorsm/websites-by-technology (4 users) $0.008 per row + $0.015 per start. Most of those read a prebuilt database (some with e-mails and phone numbers, which this Actor does not return). This Actor checks every website live at run time, works for any of about 480 technologies and any of 238 countries, and shows the evidence for each match.

Control your cost

• maxResults is the most you can be charged (maxResults x $0.005). The run stops as soon as it is reached.
• maxSitesToScan caps how many candidates are checked (scanning is free, but it takes time).
• Before scanning, the run logs its plan and compares it with your maximum charge per run. When the next website could pass it, no new website is started: SUMMARY.status is LIMIT_REACHED and SUMMARY.notProcessed.count says how many candidates were not scanned.
• Every row has charged: true or false. If Apify restarts the run, websites already delivered are skipped and not charged again.

How to use it

1. Technologies: e.g. Shopify, or several (WooCommerce, Magento). Names and categories are matched without regard to case; common short names work too (woo, wp, GA4, gtm, ecommerce). Turn on Require all technologies for "Shopify AND Klaviyo".
2. Countries: two-letter codes (US, DE, GB, TW, JP ...) or global.
3. Popularity: the top N websites to search (1,000 to 1,000,000), and optionally Skip the most popular (e.g. 10,000) to reach mid-sized businesses instead of global brands.
4. Optional: domain filters (tlds like de or co.uk, domainContains, excludeDomains) and enrichment (authority, traffic rank).
5. Click Start. Websites (overview) shows the key columns; Websites (all fields) has the full stack and evidence, ready for CSV or Excel.

The country lists rank websites by Chrome visits from that country, so an international brand popular in Germany is in the German list. For businesses based in a country, add its domain ending (e.g. tlds: ["de"]).

What the fields mean

• Popularity (countryRankBucket, countryRankLabel): the website's bucket in the Chrome UX Report list of that country for the month in this run's dataRelease (crux-202608 = August 2026 in the example above). Buckets, not exact ranks: "Top 10K" means somewhere between 5,001 and 10,000. listedIn shows every chosen country's bucket when you pick several.
• matchedTechnologies / matchEvidence: which of your technologies were found, with up to 3 pieces of evidence each.
• technologies: everything detected, with confidence (high = a clear fingerprint; medium = weak hints only). source: "dns" = seen in public DNS records.
• emailProvider / emailSecurity: the mailbox provider from the domain's MX and SPF records (Microsoft 365 behind a Hornetsecurity gateway is Microsoft 365, with emailSecurity: "Hornetsecurity"). self-hosted or other = mail servers we do not recognize.
• authorityScore / referringDomains (enrichment): our 0-100 score from the Common Crawl web graph, not Ahrefs DR or Moz DA. globalTrafficRank / trafficTrend: worldwide Chrome bucket and its 6-month trend.
• SUMMARY (key-value store): scanned, readable, matched and unreadable counts with reasons and examples, matchRate, topTechnologiesSeen, stoppedBecause and the cost plan.

Use it from code

curl -X POST "https://api.apify.com/v2/acts/tidytools~website-lists/run-sync-get-dataset-items?token=YOUR_TOKEN" \

With AI agents (MCP): connect Apify's MCP server (https://mcp.apify.com?tools=tidytools/website-lists) to Claude, Cursor or any MCP client and ask, for example, "Find 30 Shopify stores popular in the Netherlands, skipping the top 10,000 sites". Minimal input: {"technologies": ["Shopify"], "countries": ["NL"]}. Invalid inputs are free rows with errorType: "invalid_input".

Limitations

• Only websites in the Chrome UX Report lists (websites with enough Chrome traffic; up to 1 million per country, fewer for small countries). Very small shops are not in the lists.
• One page per website: only the home page (and its response headers and DNS records) is checked. Technologies used only on other pages, after login or loaded later by JavaScript may be missed. Detection is fingerprint-based: products without a public fingerprint in our list cannot be found.
• No contact details: no e-mail addresses or phone numbers of people. Use the Contact Details Extractor by TidyTools on the results if you need the contact page data a website publishes.
• Some websites cannot be read: in our test runs 20% to 40% of candidates were skipped as unreadable (bot protection, robots.txt, down). Big brands block more often than mid-sized sites. They are free and counted in SUMMARY.unreadableByReason.
• Popularity is a bucket, not traffic numbers, and it reflects Chrome users only.
• Lists are monthly: the newest month is published by Google in the second week of the following month.

Responsible use

The Actor reads public home pages and public DNS records with an honest user agent (TidyToolsWebsiteLists), and it does not read a website whose robots.txt disallows our crawler. It does not solve CAPTCHAs, bypass bot protection or log in. It returns company website data only, no personal data. If you contact the businesses you find, follow the rules that apply to you (for example the GDPR, the CAN-SPAM Act and each website's terms), and remove anyone who asks you to.

FAQ

Does the Actor collect usage data? The Actor sends one anonymous usage counter per run (input type, item count range, outcome) to improve the tool; no URLs, content or account data.

Why were only a few websites found? The technology is rare among the websites scanned. Check SUMMARY.matchRate and stoppedBecause, then raise maxSitesToScan or maxRank, or skip the biggest websites with skipTopRank (big brands rarely run Shopify or WordPress).

What if nothing is found? The run ends successfully with one free row (found: false) that says how many websites were scanned and read, and nothing is charged. The most popular websites are scanned first, so a rare technology can need a larger maxSitesToScan or a deeper maxRank (for example, no match in the first 100 of Taiwan's top 10,000 for WordPress is possible).

What happens with a misspelled technology or an unknown country? Each unknown value becomes a free invalid_input row (technologies come with "did you mean" suggestions) and the run still ends as succeeded. Unknown values are ignored when at least one valid technology or country is left; with "Require all technologies" on, or when nothing valid is left, nothing is scanned or charged. "Skip the most popular" at or above "Popularity: top N" also ends with a free explanation row. Pasted lists are read forgivingly: commas, semicolons, |, line breaks and spaces separate entries (US DE, Shopify WooCommerce), surrounding quotes and brackets are removed, and text values such as "false" or "50k" are understood. A name with "and" (Shopify and Klaviyo) is refused for free with a hint to use separate entries plus Require all technologies, because the Actor cannot know whether you meant "any" or "all".

What if I mistype an input field name? Common alternatives are mapped (technology, country, limit, max_results ...). Any other unknown field is ignored and reported in a free invalid_input row; if you gave no technologies but an unknown field, the run stops (free) instead of returning random websites.

What if one country's list cannot be downloaded? With several countries the others still run and the missing one is reported in a free list_unavailable row (SUMMARY.listsUnavailable). With only one country the run ends as failed, nothing charged.

How fresh is the data? The candidate lists are the monthly Chrome UX Report (dataRelease, e.g. crux-202608 = August 2026; Google publishes a month in the second week of the next one). The technologies are detected live from the website's home page when you run the Actor, not from a stored database.

Why is a website I know missing? It may be outside the chosen bucket, unreadable from our network (see SUMMARY.unreadableExamples) or use the technology only on other pages.

Does a DNS record count as a match? Only for products that live in DNS (e-mail hosting, e-mail security). A shopify-verification-code TXT record or an SPF include does not make a website a Shopify store: the platform must be seen on the page.

Are adult websites included? No by default (excludeAdultSites): pages with an adult label or adult words in the title or domain are skipped for free.
