Enterprise Crawling
Enterprise Crawling
We architect data pipelines that scale to billions of pages. Our enterprise crawling solution isn’t just about volume—it’s about building resilient, self-healing extraction infrastructure that delivers clean data while respecting target systems. No cap.
Technical Architecture
Our crawling stack is built on distributed microservices that coordinate through message queues. At the core, we run Scrapy with custom async Python extensions for high-throughput HTML parsing. For JavaScript-heavy sites, we deploy Playwright clusters with stealth plugins that evade headless detection. The orchestrator layer manages Crawl Frontier logic, prioritizing URLs based on business value and politeness scoring. We’re talking concurrent requests in the thousands, with automatic retry backoff when servers throttles us. Each node maintains its own IP Rotation pool, and we use Redis-backed session state for Session Persistence across distributed workers.
Data Quality & Validation
Raw HTML is messy. Our pipeline strips noise through multi-stage cleaning: first, we normalize inconsistent HTML using BeautifulSoup’s parser, then apply XPath and CSS Selector extractions against versioned selector maps. Duplicate detection uses SimHash clustering to catch near-identical pages, and Deduplication runs at both URL and content levels. For schema validation, we use Pydantic models that reject records failing type checks or regex constraints. Every extraction logs lineage back to source URL, timestamp, and selector version—this is critical for Data Observability when sites change structure.
Anti-Bot Strategy
Sophisticated sites fingerprint browsers through TLS Fingerprinting , Canvas API Detection , and Browser Fingerprinting . We counter with residential proxies that provide legitimate ISP IPs, TLS client hello randomization, and stealth plugins that spoof 50+ fingerprint vectors. For Honeypot detection, our scrapers validate CSS visibility before following links. When CAPTCHA challenges appear, we route to 2Captcha and Anti-Captcha services with human solvers. All proxy sessions rotate after 10-50 requests based on target sensitivity.
Compliance & Ethical Standards
We operate under GDPR, CCPA, and DPDP Act 2023 guidelines. Our data processing agreements cover personal data handling, retention limits, and right-to-be-forgotten workflows. For Data Sanitization , we strip PII from raw extracts before storage. Robots.txt directives are respected programmatically—we parse crawl-delay hints and adjust rates accordingly. Ethical scraping means not overwhelming targets, respecting rate limits, and avoiding business-impacting load during peak hours.
