Website Tech Detector

Overview

Website Tech Detector is an Apify actor that identifies the technologies and frameworks used by any website. Similar to Wappalyzer, it analyzes page HTML, JavaScript sources, stylesheets, HTTP headers, and meta tags to detect CMS platforms, JavaScript frameworks, CSS frameworks, analytics tools, CDN providers, and hosting platforms. Process multiple websites in a single run for technology market research, competitive analysis, and tech stack auditing.

Features

• Detect CMS platforms (WordPress, Shopify, Squarespace, Webflow, and more)
• Identify JavaScript frameworks (React, Next.js, Vue.js, Angular, Svelte, etc.)
• Find analytics and tracking tools (Google Analytics, Hotjar, Mixpanel, etc.)
• Detect CDN providers (Cloudflare, AWS CloudFront, Fastly, Vercel, etc.)
• Identify CSS frameworks (Tailwind CSS, Bootstrap, Material UI, etc.)
• Determine hosting platforms (Vercel, Netlify, AWS, Google Cloud, etc.)
• Technology count and comprehensive tech stack summary
• Bulk processing of multiple URLs
• Server and generator detection from HTTP headers

Use Cases

• Competitive Analysis: Understand what technologies your competitors use
• Market Research: Survey technology adoption across industry verticals
• Sales Intelligence: Target companies using specific technologies
• Technology Auditing: Catalog the tech stack across your organization's web properties
• Due Diligence: Assess technical infrastructure during company evaluations

Input Configuration

Parameter	Type	Default	Description
urls	Array	["https://anthropic.com", "https://stripe.com"]	Website URLs to analyze
detailed	Boolean	true	Include script and stylesheet counts

Output Format

Each result includes the URL and detected technologies grouped by category (CMS, JS frameworks, analytics, CDN, CSS frameworks, hosting), plus a total technology count. Results are stored in the default Apify dataset and can be exported to CSV, JSON, or Excel.

Integration

Use this actor with Apify schedules to monitor technology changes over time. Connect to CRM systems via Apify integrations to enrich lead data with tech stack information. Access results via the Apify API for custom analysis.

Limitations and Notes

Technology detection is based on pattern matching of HTML source, script URLs, and HTTP headers. Some technologies may not be detectable if they do not leave identifiable patterns. Server-side technologies without client-side signatures are harder to detect. The actor uses Puppeteer to render JavaScript, which helps detect client-side frameworks but requires at least 2048 MB of memory. Detection accuracy is best for popular, well-known technologies. Custom or obscure tools may not be identified.
