Cloudflare's new product, likely relevant to cloud infrastructure and developer experience.
Summary
Cloudflare's Precursor uses continuously injected JavaScript to collect session-wide behavioral signals (mouse arcs, cognitive delays, hand tremor) across the full user journey, complementing Turnstile's 3B daily challenges. By analyzing physics-constrained human movement patterns versus bots' linear interpolations, it raises the cost of automation at scale. This extends client-side detection beyond CAPTCHA moments to every page interaction, reducing friction for legitimate users.
