Why Know Your Competitors Tech Stack?
Knowing what technologies your competitors use gives you strategic advantage. BuiltWith charges $295/month for this. Wappalyzer has limits.
What You Can Detect
With the right approach, you can identify:
- Frontend: React, Vue, Angular, Next.js, Svelte, Tailwind
- CMS: WordPress, Shopify, Wix, Squarespace, Webflow
- Analytics: Google Analytics, Hotjar, Mixpanel, PostHog, Segment
- Marketing: HubSpot, Intercom, Mailchimp, Klaviyo
- Hosting: Cloudflare, AWS, Vercel, Netlify
- Payments: Stripe, PayPal, Square
- Support: Zendesk, Crisp, Tawk.to
How It Works
The detection is based on HTML signatures - specific patterns in the page source that reveal what tools are running:
# Example: detecting React
if "react.production.min.js" in html or "__NEXT_DATA__" in html:
print("React detected")
# Example: detecting Stripe
if "js.stripe.com" in html:
print("Stripe detected")
