DataLayer Lens

A clearer way to inspect, debug, and understand your dataLayer.

DataLayer Lens is a DevTools extension built for people who work with Google Tag Manager, analytics, CRO, and modern web applications. It gives you a reliable, easy-to-read view of dataLayer activity so you can validate events, debug implementations, and understand what’s really happening on the page.

Whether you’re QA’ing a tracking setup, diagnosing missing events, or working through a complex user journey, DataLayer Lens helps you stay focused and in control.



Features

Real-time dataLayer monitoring

View dataLayer events as they happen directly inside DevTools. No page refreshes or console digging required.

Per-domain settings

Configuration is saved per domain, so each site behaves the way you expect when you come back to it.

Event grouping

Related events can be grouped by trigger, making it much easier to follow event sequences and understand intent.

Pagination for large event histories

Work comfortably with high-volume sites by paging through events instead of loading everything at once.

Optional console logging

Send events to the browser console when you want deeper inspection or quick debugging alongside other logs.

Event filtering

Filter events by name using include or exclude modes to reduce noise and focus on the signals that matter.

Copy and export

Copy individual events or export the full event history to JSON for sharing, documentation, or further analysis.

Persist events across navigations

Keep a continuous record of events as you move between pages, even when the dataLayer would normally reset.

Cleane UI designed for daily use

A fast, responsive interface with a dark theme, subtle animations, and syntax highlighting that stays readable during long debugging sessions.



Built for real-world workflows

DataLayer Lens is designed to fit naturally into how GTM specialists, analysts, CRO teams, and developers actually work. It stays lightweight, avoids unnecessary abstraction, and gives you just enough structure to make sense of complex implementations.

Install it once and keep it open while you work. It quickly becomes part of your everyday toolkit.
