#backoff

Learn production-grade async scraping in Python with asyncio + aiohttp: bounded concurrency, per-host limits, retry/backoff, timeouts, and proxy rotation patterns. Includes a complete working crawler template.

Learn a production-safe retry strategy with status-code rules, backoff, and a Python helper you can drop into any scraper.

Most scrapers fail because of networking, not parsing. Here are sane timeout defaults, a retry policy that won’t DDoS a site, and a drop-in requests/httpx implementation.
