Designing a Reliable Scraping Architecture
Design an end-to-end scraping system: scheduler, URL queue, crawler pool, proxy layer, parser, storage, and monitoring. Production-ready Python code with architecture diagrams.
Developer Guides
Monitoring Proxy Performance: Latency, Success Rate, and Alerts
Learn how to instrument, monitor, and alert on proxy performance — track latency percentiles, success rates, error patterns, and bandwidth. Code examples in Python, Node.js, and Go.
Scaling Proxy Requests with Concurrency Control
Master concurrency patterns for proxy-based scraping: asyncio semaphores, Promise pools, Go worker pools, rate limiters, and backpressure. Production code in Python, Node.js, and Go.
Building a Proxy Middleware Layer for Scraping
Design and build a production-grade proxy middleware layer with retry logic, failover, and metrics. Complete implementations in Python and Node.js using ProxyHat.
Rotating Proxies with Playwright: Complete Developer Guide
Learn how to configure proxy rotation in Playwright — per-context proxies, stealth settings, geo-targeting, concurrent scraping, and production-ready patterns with code examples.
Using Proxies in Go: HTTP Client & SDK Guide
Learn how to configure proxies in Go using net/http and the ProxyHat Go SDK. Covers authentication, rotation, geo-targeting, goroutine concurrency, and production best practices.
Using Proxies in Node.js (Axios + Puppeteer + SDK)
Learn how to configure proxies in Node.js with Axios, Puppeteer, Playwright, and the ProxyHat SDK. Includes code examples for rotation, geo-targeting, retries, and concurrent scraping.
Using Proxies in Python (Requests + ProxyHat SDK)
Learn how to use proxies in Python with the Requests library and ProxyHat SDK. Covers authentication, rotation, geo-targeting, error handling, and async scraping.
