📋 What This Actor Does

Website Tech Stack Scanner efficiently identifies technologies powering any website. Using a smart multi-tier approach, it prioritizes fast, resource-light methods before resorting to browser rendering. Perfect for:

• Technology Research - Discover what technologies competitors use
• Lead Generation - Find websites built with specific tech stacks
• Security Analysis - Identify WAFs and security layers
• Development Planning - Research technology choices for projects
• Market Intelligence - Track technology adoption trends

✨ Key Features

• Smart Detection Strategy - HTTP headers → Static HTML → API probes → Browser rendering
• Comprehensive Analysis - Frameworks, CMS, libraries, WAFs, analytics, hosting
• WAF Detection - Identifies Cloudflare, Akamai, PerimeterX, Imperva, and more
• API Endpoint Probing - Discovers backend APIs and frameworks
• Fast & Efficient - Lightweight analysis before browser usage
• Structured Data - Extracts JSON-LD and Open Graph metadata

🚀 Quick Start

Basic Usage - Single Website

{
"urls":["https://example.com"]
}

Advanced Usage - Multiple Sites with Deep Analysis

{
"urls":[
"https://example.com",
"https://another-site.com"
]
}

Batch Analysis

{
"urls":[
"https://site1.com",
"https://site2.com",
"https://site3.com"
]
}

📊 Input Parameters

Internal Runtime Defaults

The actor now manages advanced runtime tuning internally for consistent output quality:

• Concurrency — fixed internally
• Browser fallback — enabled internally
• API endpoint probing — enabled internally
• Request timeout — fixed internally

📈 Output Data Structure

Each website analysis includes:

{
"url":"https://example.com",
"status":"success",
"technologies":{
"frontend":["React 18.2.0","Next.js 13.4.0"],
"backend":["Node.js","Express"],
"cms":["WordPress 6.3"],
"analytics":["Google Analytics","Hotjar"],
"hosting":["Vercel"],
"cdn":["Cloudflare"],
"libraries":["jQuery 3.6.0","Bootstrap 5.2"]
},
"waf":{
"detected":true,
"provider":"Cloudflare",
"confidence":"high"
},
"apis":{
"graphql":true,
"rest":true,
"endpoints":["/api/v1","/graphql"]
},
"metadata":{
"title":"Example Website",
"description":"Example description",
"structuredData":{...}
},
"server":{
"software":"nginx/1.21.0",
"headers":{...}
},
"detectionMethod":"static",
"scannedAt":"2024-12-11T10:30:00.000Z"
}

Output Fields

• url - Analyzed website URL
• status - Analysis status (success/failed/partial)
• technologies - Categorized tech stack
• waf - Web Application Firewall details
• apis - Discovered API endpoints
• metadata - Page metadata and structured data
• server - Server and hosting information
• detectionMethod - How technologies were detected (static/browser/mixed)
• scannedAt - Analysis timestamp

🎯 Detection Methods

1. HTTP Headers Analysis (Fastest)

• Server headers
• X-Powered-By headers
• Set-Cookie patterns
• Security headers

2. Static HTML Parsing

• Meta tags
• Script src attributes
• Link tags (stylesheets, fonts)
• HTML comments and patterns

3. API Endpoint Probing

• Common API paths: /api, /graphql, /_next/static
• CMS endpoints: /wp-json, /admin
• Framework-specific paths: /_nuxt/, /__nextjs_

4. Browser Rendering (Fallback)

• Window object inspection
• Dynamic content loading
• Client-side frameworks (React, Vue, Angular)
• JavaScript libraries

🔍 Detected Technologies

Frameworks & Libraries

• Frontend: React, Vue, Angular, Svelte, Next.js, Nuxt.js, Gatsby
• Backend: Express, Django, Laravel, Ruby on Rails, ASP.NET
• UI: Bootstrap, Tailwind CSS, Material-UI, Ant Design

CMS & Platforms

• WordPress, Drupal, Joomla, Shopify, Magento, Wix, Squarespace

WAFs & Security

• Cloudflare, Akamai, PerimeterX, Imperva, Kasada, Datadome

Analytics & Marketing

• Google Analytics, Tag Manager, Facebook Pixel, Hotjar, Mixpanel

Hosting & CDN

• Vercel, Netlify, AWS, GCP, Azure, Cloudflare, Fastly

⚡ Performance Tips

Recommended Settings

Cost Optimization

1. Disable Playwright for static sites (faster, cheaper)
2. Reduce concurrency to avoid rate limits
3. Use proxies for large batches
4. Filter URLs to analyze only relevant pages

🔧 Configuration Examples

Security Audit

{
"urls":["https://target-site.com"]
}

Competitor Analysis

{
"urls":[
"https://competitor1.com",
"https://competitor2.com",
"https://competitor3.com"
]
}

Lead Generation (Find WordPress Sites)

{
"urls":["https://site1.com","https://site2.com"]
}

🆘 Troubleshooting

Common Issues

Detection Incomplete

• The actor already runs browser fallback automatically for SPA sites
• Some sites may block automated detection
• Try enabling proxy configuration

Timeout Errors

• Retry with fewer URLs in a single run
• Check if site is accessible

WAF Blocking

• Enable Apify Proxy
• Reduce request frequency
• Some WAFs may block all automated access
