Detect CMS, JavaScript frameworks, analytics tools, CDN providers, hosting platforms, and 50+ technologies from any website URL — fast and at scale.

What does Website Technology Stack Detector do?

Website Technology Stack Detector is a powerful Apify actor that analyzes any website and identifies the technologies it uses. It scans HTML source code, response headers, script tags, meta tags, and link elements to detect content management systems, JavaScript frameworks, analytics tools, CDN providers, hosting platforms, e-commerce solutions, marketing tools, and CSS frameworks.

Think of it as your own Wappalyzer alternative or BuiltWith alternative — but running on Apify's infrastructure with full API access, bulk processing, and pay-per-event pricing.

Perfect for: sales prospecting, competitor analysis, market research, lead generation, technology auditing, and data enrichment.

Key Features

• 50+ technologies detected across 8 categories
• Bulk processing — analyze hundreds or thousands of websites in a single run
• Fast & reliable — built on Crawlee's CheerioCrawler for efficient HTML parsing
• Auto-retry — failed requests are retried automatically (up to 2 retries)
• PPE monetization — pay-per-event pricing support for Apify marketplace
• Structured output — clean JSON results organized by technology category
• Header analysis — detects server software, CDN, and hosting from HTTP headers
• CSS framework detection — identifies Bootstrap, Tailwind CSS, Bulma, Foundation

Input

{
"urls":[
"https://www.shopify.com",
"https://www.apple.com",
"https://www.stripe.com",
"https://github.com"
],
"maxRequestsPerCrawl":1000
}

Input Parameters

Output

Each URL produces a detailed result object in the dataset:

{
"url":"https://www.shopify.com",
"cms":["Shopify"],
"frameworks":["React","Next.js"],
"analytics":["Google Analytics","Google Tag Manager"],
"cdn":["Cloudflare","Amazon CloudFront"],
"hosting":[],
"ecommerce":["Stripe"],
"marketing":["Intercom"],
"cssFrameworks":[],
"server":"cloudflare",
"poweredBy":null,
"generator":null,
"language":"en",
"isMobileResponsive":true,
"isHttps":true,
"scriptCount":23,
"topScripts":["https://cdn.shopify.com/..."],
"detectedCount":7,
"scrapedAt":"2026-03-16T12:00:00.000Z"
}

If a URL fails:

{
"url":"https://unreachable-site.com",
"error":"Failed to fetch website",
"cms":[],
"frameworks":[],
"analytics":[],
"detectedCount":0,
"scrapedAt":"2026-03-16T12:00:00.000Z"
}

Use Cases

• Sales Prospecting — Find all Shopify stores, WordPress sites, or companies using specific analytics tools in your target list
• Competitor Analysis — Discover which technologies your competitors are using and track adoption trends
• Market Research — Analyze technology market share across industries or geographies
• Lead Generation — Build targeted prospect lists based on technology stack (e.g., "all sites using HubSpot but not Intercom")
• Technology Auditing — Audit your own portfolio of websites for consistency and compliance
• Data Enrichment — Enrich CRM records with technology stack data for better segmentation
• Migration Planning — Identify sites still running legacy CMS or frameworks for upgrade opportunities
• Agency Pitching — Find potential clients using outdated technologies you can help them upgrade

Pricing

This actor supports Pay-Per-Event (PPE) pricing on the Apify marketplace. You are charged per website analyzed. The actor automatically stops processing when your budget limit is reached, so you never overspend.

Free tier usage is also supported — the actor works the same way without PPE, storing all results in the dataset.

FAQ

Q: How accurate is the detection? A: The actor uses regex-based pattern matching on HTML source code and HTTP headers. It's highly accurate for technologies that leave clear signatures (like WordPress, React, Google Analytics). Some technologies may not be detected if they don't leave identifiable patterns in the initial HTML response.

Q: Does it work with Single Page Applications (SPAs)? A: The actor fetches the initial HTML response using CheerioCrawler. Most meta tags, script sources, and link elements are present in the initial HTML even for SPAs. However, technologies loaded dynamically via JavaScript after page load may not be detected.

Q: Can I analyze thousands of websites? A: Yes! The actor uses Crawlee's CheerioCrawler which efficiently processes URLs with automatic retries and concurrency management. Set maxRequestsPerCrawl to control the limit.

Q: What if a website blocks the request? A: The actor uses a realistic browser User-Agent header. Failed requests are automatically retried up to 2 times. For heavily protected sites, consider using a proxy configuration.

Q: How is PPE pricing calculated? A: Each URL analyzed (whether successful or failed) counts as one tech-detected event. You set your budget limit, and the actor stops gracefully when it's reached.

Q: Is this a Wappalyzer alternative? A: Yes — it provides similar technology detection capabilities but runs on Apify's cloud infrastructure with full API access, bulk processing, and structured JSON output. It's ideal for automated pipelines and large-scale analysis.
