How to Find Any Website's Tech Stack in 2026 (Step-by-Step)

Q: What's the easiest way to find what framework a website uses?

Use [AIWebsiteDetector.com](/) for an instant readout. For manual inspection, check for `_next/static` (Next.js), `__vue__` in the DOM (Vue), or `ng-version` attributes (Angular).

Q: How do I know what CMS a website uses?

The fastest method: check for `/wp-content/` in source (WordPress), `ghost.io` in scripts (Ghost), `squarespace.com` in CDN URLs (Squarespace). Or use [AIWebsiteDetector.com](/) for instant detection.

Framework: React, Next.js, Vue, Angular, Svelte, etc.

Hosting: Vercel, Netlify, Cloudflare, AWS, etc.

Analytics: Google Analytics, Segment, Mixpanel, Plausible

CDN: Cloudflare, Fastly, CloudFront

Step 2: Inspect the HTML Source

Press Ctrl+U (Windows) or Cmd+U (Mac) to view source. Search for these patterns:

To find the builder:

/wp-content/ → WordPress

webflow.com in URLs → Webflow

framerusercontent.com → Framer

cdn.shopify.com → Shopify

static.wixstatic.com → Wix

To find the frontend framework:

Look for

→ React/Vue app

_next/static/ → Next.js

__nuxt → Nuxt.js

ng-version attribute → Angular

To find the CMS:

Look for the generator meta tag:

Step 3: Check Network Requests

Open Chrome DevTools (F12) → Network tab → reload the page:

Filter by All to see everything loading

Click the main document (first entry) → Headers tab

Look at response headers for platform signals

Filter by XHR/Fetch to see API calls — these reveal backend frameworks

API call patterns:

/wp-json/ or /wp-admin/admin-ajax.php → WordPress

/api/builder/ → Webflow CMS

/storefront/ or /cart.js → Shopify

---

Step 4: Read the JavaScript Globals

Open the browser console (F12 → Console) and check for global variables:

// Check for common platform globals

Type these one by one in the console. A defined object means the platform is active.

---

Step 5: Use DNS and WHOIS Data

DNS records can reveal the hosting provider:

CNAME to vercel-dns.com → Vercel

CNAME to netlify.com → Netlify

CNAME to webflow.io → Webflow (before custom domain)

MX records starting with aspmx.l.google.com → Google Workspace

Use MXToolbox or dig from the terminal:

dig CNAME example.com

Common Tech Stacks You'll Find

Startup marketing site: Framer + Cloudflare + Segment + Intercom

Check the careers page: Job listings often mention the tech stack explicitly.

Look at GitHub: Many companies have public repos with their stack visible.

Ask LinkedIn: Engineering posts often mention the technology used.

Frequently Asked Questions

Can I detect the tech stack of any website?

You can detect most sites' stacks with high accuracy. Sites that actively obfuscate (proxy CDN assets, remove generator tags, custom-bundle scripts) are harder to identify, but patterns still leak through in DOM structure and API calls.
