Website Tech Stack Detector — BuiltWith / Wappalyzer Alternative

Find out what technologies any website runs — from just a URL. A cheaper, keyless, reliable alternative to BuiltWith and Wappalyzer. Detects the e-commerce platform, CMS, JavaScript framework, analytics, marketing/CRM tools, payment providers, CDN and web server across 60+ common technologies.

Fast, single-request detection. No API key, no proxies, no login.

Why this vs BuiltWith / Wappalyzer

• No API key, ever — paste URLs and go. No signup, no key management, no per-key quotas.
• Cheaper — pay-per-result pricing that undercuts BuiltWith/Wappalyzer paid plans (and their official Apify actors) instead of a monthly SaaS subscription.
• Reliable — a fast, deterministic single-request fingerprint that actually returns results. (Some technographic actors on the Store fail on nearly every run; this one is built to succeed.)
• Clean structured output — a flat technologies[] list and a byCategory map, ready to drop into a CRM, filter, or enrichment pipeline.

What you get

Per site: the resolved final URL and HTTP status, the detected server and x-powered-by, a flat list of technologies (each with a name and category), and a byCategory map grouping them.

Detected categories: ecommerce, cms, framework, analytics, marketing, payments, hosting, server — covering Shopify, WooCommerce, Magento, WordPress, Wix, Squarespace, React, Vue, Next.js, Google Analytics, HubSpot, Stripe, Cloudflare, and 60+ more.

Who it's for

• B2B sales & lead-gen — target companies by the tech they use ("everyone on Shopify", "sites running HubSpot").
• Competitive intelligence — see what competitors' sites are built with.
• Agencies — qualify prospects and audit stacks at scale.
• Data enrichment — add technographics to your CRM/lists.

Notes & limits

• Detection is based on the site's homepage response (headers, HTML markers, script sources, cookies) — a fast, single-request fingerprint covering 60+ common technologies.
• Some sites behind aggressive bot protection may return limited HTML; those come back with a status other than ok (e.g. timeout, http_403) instead of failing the run.
• Detection favours precision on widely-used platforms; a "not detected" technology may still be present but not exposed on the homepage.
• Public data; you are responsible for compliant use of the output.
