Briefing

Why it matters

Every new browser API that leaks hardware or performance characteristics is a gift to anti-bot systems and a headache for scrapers. If navigator.cpuPerformance becomes widely used for fingerprinting, scraping stacks will need to spoof or normalize this signal to avoid detection, adding another layer of complexity to browser automation.

Watch next

Will major anti-bot vendors like Cloudflare or Akamai incorporate navigator.cpuPerformance into their fingerprinting heuristics within the next quarter?
