Meta Pixel Inspector is a Chrome extension designed to facilitate real-time monitoring and validation of Meta (Facebook) Pixel events. This tool runs in a convenient sidebar panel, allowing users to browse normally while keeping track of every pixel event that occurs without requiring any login. The extension provides a clean, scannable event stream, displaying essential details such as event names, pixel IDs, and timestamps at a glance.

Key features of Meta Pixel Inspector include smart validation that flags missing required parameters, detects empty fields, and checks data types and currency codes. Users can benefit from event-aware checking, which adapts validations based on event types, and a clear issue hierarchy that categorizes problems into errors, warnings, and recommendations. The extension supports multiple pixels, making it suitable for agencies and developers, and allows for easy sharing of event data.
