### Web Experiment Chrome Debugger — Targeting Visibility

Stephen Choi

**Description:** The Amplitude Instrumentation Explorer Chrome extension now shows granular targeting debug details for Web Experiments — so you can diagnose why an experiment isn't firing in seconds.

When an experiment is active, you'll see a Debugging Details panel with:

- Audience targeting — which segment matched and the assigned variant
- Page targeting — configured page view rule, URL match status, and trigger status
- Exposure status — top-level Exposed / Not Exposed at a glance
- Preview variant — override the assigned variant for quick QA without touching experiment config

**Where:** Access via the Amplitude Instrumentation Explorer Chrome extension. **When:** Available now (Update to the latest version of the extension to use).
