Rendering alone doesn't separate scraping APIs; fidelity and completeness do.
Most scraping benchmarks measure only whether pages return, not whether they're usable by AI models.
Detect throttling from response signals before hard blocks arrive.
Avoid CAPTCHAs first, then solve what you can't prevent.
Distributes scraping traffic across rotating IPs to avoid detection and bans.
Solving CAPTCHAS at the wrong architectural layer wastes money and latency.
Fix three production crashes: zombie processes, shared-memory exhaustion, and unclosed contexts.
Evading modern anti-bot detection requires mastering six independent layers, not just proxies.
Managed APIs exist because beating billion-dollar defenses alone became technically impossible.
Diagnose whether JavaScript rendering is actually needed before choosing your extraction strategy.
Silent JavaScript rendering failures corrupt AI data pipelines without any error signals.
