Lessons from crawling the web at scale [2026w17]

In this episode of Lead Prompt, I dive into the engineering realities of scaling Greppr.org past 41 million indexed documents and 0.5TB of data. Moving past management theory, I break down the engineering optimizations required to survive the chaos of crawling the web at scale. Discover how I bypassed geo-location redirects using proxies, defeated crawler tar pits with custom fail-fast timeouts, implemented rapid early-stage filters for NSFW content and non-text rich media, and eliminated index bloat through automated canonical URL deduplication.
