    "readmeSummary": "## Website Technology Stack Detector\n\nDetects and catalogs visible web technologies on public websites by passively fetching page HTML and extracting deterministic signals from headers, cookie names, meta tags, script and stylesheet references, and HTML markers. The Actor performs curated signature matching across 60+ technology categories (CMS, ecommerce, analytics, advertising, marketing, support, payments, frameworks, hosting, CDN, web servers, consent tools), returns one record per detected technology with classification, deterministic confidence, public version when exposed, contextual evidence labels, page and URL context, HTTP response metadata, and detection timestamps. Technical features include validated redirects, bounded retries, anti-bot challenge detection, resumable scanning for larger lists, framework implication rules (e.g., inferred relationships), GraphQL detection via client signals, and an independent rule set that does not rely on a third-party technology database.\n\n## Use cases\n\n- Lead enrichment with visible platform and martech signals for sales and growth teams  \n- Migration research and platform discovery for redevelopment planning  \n- Martech audits: detect analytics, tag management, advertising, marketing automation, and support tools  \n- SEO reviews and competitor monitoring of public technology stacks  \n- Detect ecommerce platforms and payment tools on public storefronts  \n- Audit SaaS marketing technology stacks for agencies and consultants  \n- Compare website frameworks, CMS, libraries, UI frameworks, and hosting providers across domains  \n- Route domains by detected framework, hosting, or infrastructure for engineering workflows  \n- Ecommerce and martech teams auditing storefront, payment, analytics, and customer support tool usage",
