Data Layer Inspector

About

Inspect, monitor, and debug dataLayer events in real time from Chrome DevTools. Compatible with SPAs.

DataLayer Inspector is the ultimate tool for digital analysts and developers who need to audit Google Tag Manager implementations and other dataLayer-based systems. This extension adds a dedicated panel to Chrome DevTools to visualize and manage all events pushed to the dataLayer in a clear and organized way.

Key Features:

- Real-Time Visualization: Observe dataLayer.push events as they occur, ordered chronologically (from newest to oldest).
- Interactive JSON Format: Explore data with a collapsible JSON tree viewer and syntax highlighting for easy reading.
- SPA Support: Automatically groups events by page load and navigation (compatible with History API), making it easy to track in Single Page Applications.
- Search and Filtering: Quickly find specific events, keys, or values ​​with the integrated search bar.
- Persistent History: Maintain event history even when navigating between pages or reloading.
- Data Export: Export the entire event history to a text file for further analysis or documentation.
- Robustness: Detects dataLayer object reassignments and captures undefined or null values ​​that other tools often miss.

Simplify your debugging workflow and ensure data quality with DataLayer Inspector.
