SDKs collect runtime signals when your app runs:

• Performance: Core Web Vitals and timings
• Errors: exceptions and stack traces
• User behavior: sessions, page views, key interactions
• Security signals: basic heuristic detections (plan/features dependent)

• Deduplication: group similar errors by signature
• Aggregation: compute trends over time
• Classification: severity and impact tagging

TestingAI runs headless browsers (Playwright/Chromium) on the Sublyzer backend to generate synthetic navigation, videos, and logs.

Retention varies by plan and policy. You can export or delete data from Settings.
