A comprehensive Chrome extension for analyzing website technologies, performance characteristics, and behavioral patterns. This tool provides detailed insights into the technical stack and operational patterns of websites you visit.
- Advanced Pattern Recognition: Identifies web technologies using comprehensive signature databases
- Real-time Analysis: Monitors network requests, storage elements, and script behaviors as you browse
- Comprehensive Coverage: Detects analytics platforms, content management systems, advertising networks, and more
- Background Activity Monitoring: Tracks unusual request patterns during idle periods
- Data Transfer Analysis: Identifies large uploads/downloads and bulk data operations
- Runtime Behavior Detection: Monitors for dynamic script loading and DOM manipulation patterns
- Request Pattern Analysis: Analyzes the ratio of data operations to total requests
- Storage Element Tracking: Monitors browser storage usage patterns
- Network Performance Metrics: Tracks request timing and data transfer volumes
- Complexity Scoring: Assigns complexity levels (Low, Medium, High) based on detected technologies
- Behavioral Risk Evaluation: Assesses potential impacts of detected patterns
- Comprehensive Reporting: Generates detailed analysis reports for export
- Download or clone this repository
- Open Chrome and navigate to
chrome://extensions/ - Enable "Developer mode" in the top right corner
- Click "Load unpacked" and select the extension directory
- The Website Analyzer icon will appear in your Chrome toolbar
- Navigate to any website - The extension automatically begins analysis
- Click the extension icon - View real-time findings and analysis
- Use the filter tabs - Sort findings by complexity level (All, High, Medium, Low)
- Export reports - Generate JSON reports of your analysis
- High/Medium/Low Counts: Number of findings categorized by complexity
- Total Count: Overall number of detected technologies and patterns
Each finding shows:
- Technology Name: The specific tool or service detected
- Complexity Level: Risk assessment (High/Medium/Low)
- Detection Method: How the technology was identified
- Technical Details: URLs, domains, or specific parameters
- User Recording Alerts: Notifications when user interaction recording is detected
- Background Operations: Warnings about unusual activity during idle periods
Generate comprehensive JSON reports containing:
- Complete findings list with technical details
- Complexity breakdown and statistics
- Timeline of detected technologies
- Behavioral analysis summary
The extension uses technology detection patterns generated from the Wappalyzer Privacy Report repository. This ensures comprehensive and up-to-date coverage of web technologies.
