The tool ensures maximum privacy and speed by performing all heuristic evaluations locally. Key Features: • Batch URL Scanning: Effortlessly analyze multiple URLs via a multiline input with a duplicate-safe normalization process. • High-Performance Queue: Features a concurrency-aware execution queue for fast bulk analysis while controlling browser-side pressure and preventing rate limits. • Advanced Classification Engine: Automatically categorizes URLs as full websites, e-commerce stores, blogs, minimal landing pages, or parked/empty domains based on intelligent scoring heuristics. • CMS & Framework Fingerprinting: Accurately detect underlying content management systems (CMS) and modern frontend web frameworks. • Comprehensive Content Metrics: Extract and evaluate vital statistics such as internal and external links, word counts, image counts, navigation elements, and overall DOM complexity. • Robust Error Handling: Explicit detection and reporting for 401, 403, 404, and 5xx HTTP categories, complete with deterministic request timeout handling and redirect chain tracking. • Seamless Data Export: Instantly export your scanned results to a CSV file for reporting, client handoffs, or further data pipeline ingestion. • Analyst-Friendly UI: Designed for productivity with a persistable dark/light theme, interactive data tables with sortable metric columns, and full-text client-side filtering. Site Analyzer Pro is optimized for manual, high-ROI scan sessions, allowing you to instantly separate high-value production websites from unreachable hosts or parked assets.
