Detect the technologies a website runs: CMS, ecommerce platform, JavaScript frameworks, analytics, CRM, marketing automation, payment processors, chat widgets, CDN, and hosting. Use it to research a competitor, qualify a sales prospect, or check what a site is built with. Reads the HTML and headers the server sends, so anything injected only by client-side JavaScript may not appear — a sparse result means little was detectable, not that the site runs nothing. Counts as one scan against the caller's plan.

Detect the technology stacks of up to 25 websites in one call, returning the full detail for each. Use it when working through a list of prospects, competitors, or portfolio sites. If you want a side-by-side view of who uses what, use compare_stacks instead. Counts one scan per URL against the caller's plan.

Scan 2-25 websites and return a side-by-side table of which technologies each one uses. Answers questions like 'which of these prospects use HubSpot vs Salesforce?' or 'how does our stack compare to our competitors?'. For the full per-site detail rather than a table, use batch_lookup. Counts one scan per URL against the caller's plan.
