Tech Stack API

Detect what any website is built with, in one call: CMS, e-commerce platform, analytics and tag managers, payment providers, JavaScript frameworks and meta-frameworks, server-side language and framework, web server, CDN, hosting platform, marketing and CRM tools, live-chat, A/B testing, search, maps, video, fonts and anti-bot services — matched against a curated, self-maintained fingerprint ruleset of 108 technologies. Each lookup performs one live fetch of the target page and matches static evidence only: response headers, cookie names, script and stylesheet URLs, meta tags and anchored HTML markers. Every detection returns the exact evidence that matched (the header, cookie, script URL or marker) and a confidence level — detected from direct evidence, or implied from a certain relationship, such as WooCommerce implying WordPress and Next.js implying React — with framework versions captured where the site exposes them. Scan one site, or up to 10 concurrently in a batch with per-target errors reported inline; list the full detectable catalogue so you know exactly what a scan can and cannot find. Ideal for sales prospecting and lead enrichment (what does this prospect run?), competitor analysis, migration planning and market-share research. Non-public targets are refused, and the ruleset is this provider's own — no third-party detection service behind it.
