Tech Stack Detector

Identify the software behind a list of websites for prospecting, account qualification, competitive research, and market mapping. Each result names the detected technologies, groups them by category, and includes the exact public signal behind every match.

The bundled fingerprint set covers 255 named technologies across CMS, ecommerce, JavaScript and web frameworks, analytics, advertising, marketing automation, payments, hosting, CDNs, security, databases, and other web infrastructure. That is the actual locally bundled count—not a claim of thousands of rules.

Input

Add one or more domains or URLs to urls. The scheme is optional. maxUrls limits the batch to at most 1,000 unique websites.

{
  "urls": [
    "stripe.com",
    "shopify.com"
  ],
  "maxUrls": 10
}

Output

Each tech_stack_record contains:

requested and final URL, HTTP status, page title, and reported server
technologies: name, category, exact evidence, and whether the technology was inferred
categories: a category-to-technology roll-up
technology_count, stable record_key, and analysis timestamp

The detector reads the website's public logged-out HTTP response: response headers, Set-Cookie names (never values), referenced script/link/image/form URLs, generator metadata, and page markup. It does not execute JavaScript or claim browser-DOM, DNS, certificate, XHR, or active-probe coverage.

Billing

The platform charges a $0.02 Actor start. A tech_stack_record event is $0.04 at the base tier and is charged only when at least one supported technology is detected and its record is delivered. Volume tiers reduce the event price. A blocked or faulted fetch, or a successfully fetched page with no supported fingerprint match, does not incur the record charge.

Detection quality

Direct matches retain the exact header, cookie name, referenced URL, generator value, or markup pattern that produced them. Technologies inferred from another reliable match are explicitly labeled inferred. The 255-name catalog combines the Actor's original high-confidence rules with the publisher's existing WebAppAnalyzer-derived bundled rule asset; see THIRD_PARTY_NOTICES.md for provenance and license details.
