Find out what any website is built with — in bulk. Paste a list of domains and get the CMS, ecommerce platform, analytics and ad pixels, CRM and marketing automation, payment providers, hosting, CDN, JavaScript frameworks and more, plus the company's email provider (Google Workspace, Microsoft 365 …) and email/marketing services (SendGrid, HubSpot, Mailchimp …) from public DNS records.
A fast, affordable alternative to BuiltWith and Wappalyzer lookups, with 7,600+ technology fingerprints.
Why use it
- Lead generation & sales prospecting: build lists of Shopify stores, WordPress sites, HubSpot or Salesforce users, sites using a competitor's product, or companies on Microsoft 365.
- Lead enrichment: add tech-stack columns to your CRM or spreadsheet of company domains.
- Competitive intelligence: see which analytics, A/B testing, chat or payment tools competitors use.
- Agencies & SaaS vendors: qualify prospects by platform ("uses WooCommerce but no email marketing tool").
- Security & IT audits: inventory web servers, CDNs and frameworks (with versions when exposed).

Pricing
Pay per website analyzed. Websites that cannot be reached, are invalid, or answer with an error/bot challenge are not charged (you still get the DNS-based results for them in the dataset). Duplicates are removed automatically. Set a maximum charge per run and the Actor stops at your limit.
How it works & limits
- Each homepage is fetched once over HTTP (no browser), and its HTML, headers, cookies, scripts, meta tags and DOM are matched against the open-source webappanalyzer fingerprints (GPL-3.0). Public DNS records are read via DNS-over-HTTPS.
- Technologies that can only be seen by executing JavaScript in a browser may be missed; most common tools are detected from HTML and script URLs.
- Sites behind aggressive bot protection may block the request; those rows are flagged and not charged.
- Only public, technical information is collected. The Actor does not extract personal data such as emails or phone numbers of individuals.
