Playwright Init Scripts

Detection approach

Playwright initialization scripts detected. The global `window.__pwInitScripts` object was found in the document context. Authentic consumer browsers do not contain these internal Playwright variables, proving the session is operated by Playwright's automation engine.

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

None. This variable is only present when Playwright injects initial scripts into the document.
