Real-Time Scraping
Real-Time Scraping
We build event-driven data pipelines that push updates the moment they appear. Our real-time scraping solution combines websocket monitoring, change detection algorithms, and Webhooks delivery to ensure you never work with stale data. In fast-moving markets, latency matters—we optimize for sub-second detection.
Technical Architecture
Real-time detection requires multiple strategies. For sites with WebSocket connections or Server-Sent Events, we maintain persistent connections with automatic reconnection. For polling-based detection, we implement adaptive intervals based on target change frequency—some sources get checked every few seconds, others hourly. Our change detection uses content hashing with perceptual diff algorithms to catch visual changes even when DOM structure shifts. The orchestrator routes detected changes through message queues with at-least-once delivery guarantees.
Data Quality & Validation
Real-time doesn’t mean sloppy. Every change event validates against Pydantic schemas before delivery. Duplicate detection uses content hashing with temporal clustering to avoid sending the same update multiple times. For sites that rapidly toggle states (price flashing, availability changes), we implement hysteresis—requiring sustained state for N seconds before triggering alerts. Deduplication runs at both the event and content levels.
Anti-Bot Strategy
Frequent requests trigger aggressive anti-bot measures. We implement IP Rotation with longer rotation cycles during high-frequency monitoring. Stealth Plugins ensure every request appears from a unique browser session. For sites using User Behavior Analytics , we vary interaction timing and navigation patterns to avoid pattern detection. Residential proxies provide authentic ISP contexts that survive longer under scrutiny.
Compliance & Ethical Standards
High-frequency monitoring must respect target infrastructure. We implement polite rate floors that prevent request flooding even during critical monitoring windows. For commercial data, we ensure our monitoring doesn’t impact target site performance—a key ethical consideration. GDPR and DPDP Act 2023 compliance extends to real-time data—any personal data detected in real-time streams gets immediately masked or excluded from delivery.
