Who uses this

• Sales teams and agencies: find prospects that use (or do not use) a tool. "Shopify stores without a review app", "WordPress sites without analytics", "companies on Microsoft 365".
• SaaS companies: list the websites that use a competitor and build a switching campaign.
• Lead enrichment: add a tech stack column to a list of company websites before outreach.
• Market research: count how many sites in a niche use each platform. The run summary lists the most common technologies across your list.

1. Paste your websites, one per line. https://www.example.com and example.com both work.
2. Click Start.
3. Export to CSV, Excel or JSON, or send the results to Google Sheets, your CRM, Make, Zapier or n8n.

evidence tells you how each technology was found: page code, a response header, a cookie, a meta generator tag, a DNS record, or "implied by" another technology (Next.js implies React).

Status column

Status	Meaning	Charged
ok	The website was read and analyzed	Yes
unreachable	The website does not exist or did not answer	No
blocked	The website refuses automated visitors (technologies seen in headers and DNS are still listed)	No
robots_disallowed	robots.txt asks robots not to read the page	No
invalid_url	The input line is not a website address	No

Pricing: pay only for results

• Analyzed website: charged once per website whose page was read.
• Unreachable, blocked, invalid and duplicate websites are free.

Set a maximum cost per run in the run options and the Actor stops cleanly at your limit.

Good to know

• First page only, plain HTML: the Actor reads each website's first page without running a browser. This makes it fast and cheap (thousands of websites per run), but tools that a website loads only after a click or only through a tag manager may be missed.
• Fingerprints are our own: detection rules are written and tested for this Actor. If a technology you need is missing, open an issue and we will add it.
• Large lists: thousands of websites per run are fine. If a long run is restarted by the platform, it continues where it stopped and nothing is charged twice.

Responsible use

This Actor reads only the public first page, public response headers and public DNS records. It respects robots.txt by default, uses no logins and bypasses no protection.
