Fast, cheap and keyless — the technographics you need for sales intelligence, lead scoring, competitor research and market analysis.

Why this Actor?

Knowing what a website is built with is gold for sales and research: target every Shopify store, find sites still on an old CMS, score leads by their martech stack, or map a market's platform share. Dedicated technographics tools are expensive and per-lookup; this Actor checks a whole list at once, on plain HTTP, so it stays cheap at scale.

• Sales intelligence — filter prospects by platform (e.g. all WooCommerce sites, all HubSpot users).
• Lead scoring & enrichment — add tech signals to your CRM records.
• Competitor & market research — map CMS / e-commerce / CDN share across a list of sites.
• Agency prospecting — find sites on platforms you specialize in.

Field	Type	Default	Description
urls	array	—	Required. Websites to analyze. Paste a list or upload/link a text/CSV file.
maxConcurrency	integer	50	Sites analyzed in parallel (up to 300).
timeoutSecs	integer	30	Give up on a site after this many seconds.

Use cases in detail

1. Build a platform-targeted prospect list

Run a list of company sites, then filter ecommerce = Shopify (or WooCommerce, Magento…) to get every prospect on the platform you sell to.

2. Lead scoring by martech

marketing and analytics tell you how sophisticated a prospect is — sites running HubSpot/Segment/Klaviyo are further along and often better leads.

3. Market & competitor research

Aggregate cms / ecommerce / cdn across a market to see platform share and trends.

4. Agency prospecting

Specialize in Webflow, Shopify or WordPress? Find sites on (or off) those platforms to pitch.

Frequently asked questions

How does it detect technologies? It fetches each site's HTML and response headers and matches them against a library of fingerprints (script URLs, markers, headers). No browser, so it's fast and cheap.

How many sites can it handle? Thousands to millions — it auto-scales concurrency and streams results.

Does it render JavaScript? No — it reads the server-rendered HTML and headers, which is where the vast majority of tech signals live. Technologies injected only by later JS execution may not appear.

Why did a site show fewer technologies than expected? Some stacks are only detectable via runtime JS or are intentionally obscured. The detector focuses on high-confidence signals to keep false positives low.

Can I filter by platform? Yes — export and filter on cms, ecommerce, marketing, etc., or search allTechnologies.

---

Tips

• Filter on ecommerce / cms to build platform-specific prospect lists.
• Combine with a contact scraper to turn a tech-targeted list into outreach-ready leads.
• Raise maxConcurrency for speed on big runs.

Notes

This Actor performs standard HTTP requests and inspects publicly returned HTML and headers to infer technologies. Detection is best-effort (signal-based) and not guaranteed complete. Use on sites you have the right to analyze.
