Website Tech Stack Scraper & Technology Lookup API

Detect website technologies with Wappalyzer-compatible HTTP-header and static-HTML fingerprints. This bulk tech-stack scraper / BuiltWith alternative covers CMS platforms, JavaScript frameworks, analytics tools, CDNs, ecommerce platforms, payment processors, hosting providers, and thousands more.

What it does

Give it a list of website URLs and it returns every detected technology with category labels. Uses Wappalyzer-style fingerprints to identify 7,000+ technologies from HTTP headers and HTML source.

Detects:

• CMS platforms (WordPress, Shopify, Drupal, Wix)
• JavaScript frameworks (React, Vue, Angular, Next.js)
• Analytics (Google Analytics, Mixpanel, Hotjar)
• CDNs (Cloudflare, AWS CloudFront, Fastly)
• Ecommerce (Shopify, WooCommerce, Magento)
• Payment processors (Stripe, PayPal, Square)
• Web servers (Nginx, Apache, IIS)
• Programming languages (PHP, Python, Ruby, Node.js)
• Marketing tools, tag managers, A/B testing, live chat, and more

Use cases

• Competitive Analysis -- See what tech stack competitors use
• Lead Enrichment -- Add technology data to your prospect lists
• BuiltWith / Wappalyzer alternative workflows -- Run bulk website technology lookup without a separate API key
• Market Research -- Survey technology adoption across an industry
• Sales Intelligence -- Find companies using specific tools (e.g., all Shopify stores, all Stripe users)
• Security Auditing -- Identify outdated or vulnerable technologies

Reliability and interpretation limits

• Results are point-in-time heuristic detections from response headers and up to the first 5 MiB of static HTML.
• A missing technology does not prove absence. Client-rendered, blocked, proxied, or obfuscated tools may be missed.
• Fingerprints can produce false positives; verify important findings against the website and vendor configuration.
• Redirects are followed up to five hops and the final fetched URL is returned.
• Failed fetches remain explicit result rows with an error instead of disappearing from a bulk job.
• Large Apify runs persist every 25 completed sites so a late failure does not discard all prior work.

Pricing

$5.00 per 1,000 websites scanned. The default one-site Shopify demo costs at most $0.005 plus any platform start event. Buyer-set maximum total charge limits are honored before each scan. No API key or external technology-detection service is required.
