Stop Paying $295/mo for BuiltWith

You're currently paying: BuiltWith ($295/mo), Wappalyzer Pro ($99/mo), SimilarTech ($199/mo), StackShare Pro ($49/mo).

What if you could detect tech stacks for pennies per site?

The Tech Stack Lookup Scraper identifies 200+ technologies on any website:

• CMS platforms (WordPress, Shopify, Wix, Squarespace, Drupal, Magento)
• JavaScript frameworks (React, Vue, Angular, Next.js, Nuxt, Gatsby)
• Analytics tools (Google Analytics 4, Mixpanel, Amplitude, Segment)
• Marketing automation (HubSpot, Mailchimp, Intercom, Drift)
• CDN/Hosting (AWS, Cloudflare, Vercel, Netlify)
• Security headers and SSL analysis
• E-commerce platforms and payment processors

Pay only for what you use. No monthly subscriptions. No minimum commitments.

Why Choose This Over Traditional Tech Detection Tools

1. Pay-Per-Site, Not Per-Month

Traditional tools: $100-$300/month for unlimited lookups.

This actor: Pay per URL analyzed. Analyze 100 sites for ~$10. Analyze 1,000 for ~$75.

Analyze 500 competitor sites and still pay less than one BuiltWith subscription.

2. 200+ Technologies Detected

We detect technologies across 10 categories:

Category	Examples
CMS	WordPress, Shopify, Wix, Squarespace, Drupal, Magento, Webflow
Frameworks	React, Vue, Angular, Next.js, Nuxt, Gatsby, Svelte
Analytics	GA4, Mixpanel, Amplitude, Heap, Segment, Hotjar, FullStory
Marketing	HubSpot, Mailchimp, Klaviyo, Intercom, Drift, Zendesk
E-commerce	Shopify, WooCommerce, Magento, BigCommerce, Stripe, PayPal
CDN	Cloudflare, Fastly, Akamai, CloudFront, StackPath
Hosting	AWS, GCP, Azure, Vercel, Netlify, DigitalOcean, Heroku
SEO	Yoast, Rank Math, All in One SEO, Schema.org
Advertising	Google Ads, Facebook Pixel, LinkedIn Insight, TikTok Pixel
Security	Cloudflare, Sucuri, Wordfence, reCAPTCHA

3. Confidence Scores

Every detection includes a confidence percentage (0-100%) so you know how reliable each result is.

4. Bulk Processing with Webhooks

Process thousands of URLs in parallel. Get results delivered to your webhook when done.
