Chrome's new navigator.cpuPerformance API opens a fresh fingerprinting vector
Zyte reports that Chrome 152 will expose a navigator.cpuPerformance property, giving sites a new way to fingerprint browsers.
Briefing
- Zyte: Zyte reports that Chrome 152 will expose a navigator.cpuPerformance property, giving sites a new way to fingerprint browsers.
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?
