Step-by-Step Guide: Manual Methods for Tech Stack Discovery

Browser developer tools remain your first line of investigation for uncovering competitor technologies. Every modern browser provides powerful inspection capabilities that reveal frontend frameworks, libraries, and third-party integrations within seconds.

Inspecting Network Requests and Resources

Open Chrome DevTools (F12) and navigate to the Network tab before loading your competitor's site. Key indicators to watch for:

// React indicators in bundle names
main.chunk.js
react-dom.production.min.js
webpack.runtime.js

// Vue.js patterns
vue.global.prod.js
app.[hash].js with Vue devtools detection

// Next.js 14+ signatures
_next/static/chunks/
_buildManifest.js

The Sources panel exposes bundled JavaScript that often contains framework fingerprints. Search for telltale strings like __NEXT_DATA__ (Next.js), ng-version (Angular), or data-reactroot (React) in the HTML.

Decoding HTML Source Code

View-source analysis reveals CMS platforms, meta generators, and framework-specific attributes. WordPress sites in 2026 still leave traces like:

<meta name="generator" content="WordPress 6.5" />
<link rel='stylesheet' id='wp-block-library-css' href='/wp-includes/blocks/style.min.css' />

Modern headless CMSs like Sanity or Strapi inject different patterns:

<!-- Sanity Studio -->
<script>window.__SANITY_STUDIO_PROJECT_ID="your-project-id"</script>

<!-- Strapi indicators -->
<meta name="strapi-version" content="4.15.0" />

DNS and Infrastructure Reconnaissance

Infrastructure mapping through DNS queries reveals hosting providers and CDN usage:

# Cloudflare detection
dig example.com
# Look for cloudflare.com nameservers

# AWS CloudFront patterns
nslookup d1234abcd.cloudfront.net

# Vercel deployment detection
# Domains resolve to 76.76.21.21 (Vercel's anycast IP)
