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 " )
