Detection approach
RequestAnimationFrame timing anomaly. Bots often lock to exact 16.67ms intervals (60fps) with zero jitter, unlike real browsers whose rAF timing fluctuates with OS scheduling.
How this helps detect bots
Collect this signal alongside session context, request metadata, and other independent indicators. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.
Legitimate traffic to consider
High refresh rate monitors or browsers under hardware sync locks.
