Detection approach
WebGL supports fewer than 20 extensions. Genuine Chrome on desktop exposes 30-50 extensions. Fewer than 20 indicates a stripped-down headless context or software renderer.
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
Users with low-end graphic interfaces, older browsers, or custom WebGL blocks.
