Universal Web Crawler & Recursive Site Spider Studio (WebSonar Pro)
Autonomous recursive website crawler, link spider, and structured page dataset compiler (WebSonar, CrawlForge, SiteCartographer). Spiders full domains, extracts H1/H2s, words, and latency, and exports to JSON, CSV, and XML Sitemap.
Free Tier limit: 20 pages max
Level 1 (Direct links) • Level 2 (Sub-pages) • Level 3+ (Deep)
Crawl only URLs containing this subpath
Safe Autonomous Crawling & Zero-Telemetry Architecture
All HTTP requests, breadth-first-search queues, link graph traversals, and structured dataset compilations run in-memory within strict domain boundaries. Zero crawl data, target URLs, or extracted proprietary records are stored in any database.
Comprehensive Technical Guide & Reference
Enter any seed URL, choose your crawl depth and maximum page count, apply subpath filters (e.g. /blog or /docs), and watch the autonomous spider map out the entire domain with real-time latency and word count metrics.
11. Step-by-Step: How to Spider and Map a Website
Crawl and extract structured datasets from entire web domains:
- •Enter Seed URL: Input the homepage or starting directory URL of the target website.
- •Configure Crawl Bounds: Select crawl depth (1 to 4 levels), max page limit (20 to 100 pages), and optional path filters (e.g. `/blog` or `/docs`).
- •Watch Real-Time Discovery: The Breadth-First-Search (BFS) spider traverses internal links, logging HTTP status, response latency, Title, H1s, and word counts.
- •Export Multi-Format Datasets: Download the complete crawled catalog as a clean JSON dataset, CSV spreadsheet, or standard XML Sitemap.
22. Technical Explanation: Breadth-First-Search (BFS) Traversal
The autonomous crawler utilizes a concurrent BFS queue that discovers and indexes URLs level by level without exceeding domain boundaries:
- •Domain Boundary Guard: Ignores external outbound links, ensuring only the target hostname is spidered.
- •URL Normalization: Resolves relative paths (`/about`), strips query parameter duplicates, and unifies trailing slashes.
- •Structured Extraction: Parses the HTML DOM to extract title tags, meta descriptions, canonical links, heading hierarchies (H1/H2), and substantive body word counts.
33. Generating XML Sitemaps by Crawling
If a legacy website lacks a sitemap generator, crawling the domain compiles all discovered 200 OK URLs into a ready-to-submit `sitemap.xml` file for Google Search Console.
Frequently Asked Questions
A single-page checker only analyzes 1 specific URL. This crawler acts as an autonomous spider that discovers and crawls dozens of internal pages across the entire website in a single automated batch.
