Discover technologies powering any website
A powerful tool for analyzing websites to detect their underlying technologies, including frameworks, libraries, hosting providers, CMS platforms, and more. Get detailed insights with performance metrics and security analysis.
The Tech Stack Detector analyzes websites to identify the technologies they use, including frameworks, content management systems, hosting platforms, analytics tools, and more. It provides confidence scores for each detected technology and offers performance and security insights.
Tip: Use the Dashboard link to access additional analytics and insights about your analysis history.
The primary feature allows you to analyze any website by entering its URL. The tool will fetch and analyze the website to detect its technology stack.
Enter a complete URL including the protocol (http:// or https://)
https://example.com
Note: Some websites may block automated requests or require specific headers. If analysis fails, try a different URL or check if the website is accessible.
During analysis, a progress bar shows the current status. The analysis includes:
Analyze multiple websites at once using the batch analysis feature. This is useful for comparing competitors, auditing multiple sites, or building a technology database.
https://example1.com https://example2.com https://example3.com
Tip: Batch analysis processes URLs sequentially. For large batches, the analysis may take several minutes. Results are saved to your history automatically.
The Overview tab displays detected technologies organized by category. Each category shows the top technologies with their confidence scores.
Shows load time in milliseconds and page size in kilobytes. These metrics help assess the website's performance characteristics.
Technologies are grouped by category: Frameworks, CMS, Hosting, Analytics, Marketing, and more. Each category displays the top 3 detected technologies.
React, Vue, Angular, Next.js, Nuxt, etc.
WordPress, Shopify, Wix, Ghost, etc.
Vercel, Netlify, AWS, Cloudflare, etc.
Google Analytics, Mixpanel, Hotjar, etc.
The Detailed tab provides comprehensive information about each detected technology, including version information, descriptions, and links to official websites.
The exact name of the detected technology
Detected version number when available
Percentage indicating detection certainty
Brief description of the technology
Link to the official technology website
Confidence Score: Technologies are detected with varying confidence levels. Higher confidence indicates stronger evidence from HTML patterns, JavaScript files, and resource headers.
The Security tab provides insights into the website's security configuration, including HTTPS status and security headers.
Indicates whether the website uses HTTPS encryption. A secure connection is shown with a green badge, while insecure connections are marked with a red badge.
Lists detected security headers such as Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
Warning: Websites without HTTPS may expose user data to interception. Security headers help protect against common attacks like XSS and clickjacking.
All analyses are saved to your history, allowing you to revisit previous results, search through analyses, and filter by category.
Search through history by URL, title, or technology name
Filter results to show only analyses containing specific technology categories
Mark important analyses with a star for quick access
Remove unwanted analyses from history
Tip: Use the History panel to track changes in a website's tech stack over time by re-analyzing and comparing results.
Compare multiple websites side-by-side to analyze their technology stacks, performance metrics, and detect patterns or differences.
Export analysis results for external use, reporting, or integration with other tools. Two formats are supported: JSON and CSV.
Exports complete analysis data including all detected technologies, performance metrics, and security information.

Use Case: Export analysis data to track technology trends, generate reports, or integrate with external analysis tools.
Analyze competitor websites to understand their technology choices, identify trends in your industry, and benchmark your own stack.
Evaluate third-party vendors and partners by examining their technology implementations before engaging in business relationships.
Check websites for security configurations, HTTPS usage, and security header implementations as part of security assessments.
Quickly identify technologies used by websites during reconnaissance for projects, integrations, or research purposes.
Analyze a list of websites to build a comprehensive view of technology adoption patterns across an industry or market segment.
Understand legacy technology stacks to plan migrations and identify dependencies before undertaking modernization projects.
