Default Viewport

Detection approach

Default automation viewport size detected (exactly 800x600 for Puppeteer or 1280x720 for Playwright). Real humans browse with customized device screen resolutions and browser chrome, never with these hardcoded driver defaults.

How this helps detect bots

This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

Legitimate users resizing window viewport sizes to exactly 800x600 or 1280x720.
