Strata is a powerful Chrome add-on designed for inspecting, validating, and exporting Google Tag Manager (GTM) dataLayer information. It provides developers and technical analysts with real-time visibility into dataLayer.push() calls, allowing users to capture and analyze events as they occur. The tool supports multi-container GTM setups and includes features like color-coded event categories, searchable event logs, and the ability to pause and resume recordings, making it an essential tool for debugging and validating GTM implementations.

In addition to its real-time event capture capabilities, Strata offers schema validation, enabling users to define expected event structures and automatically validate them. Developers can export captured events in JSON format, generate test assertions for Playwright or Cypress, and create visual documentation in PNG or PDF formats. With a focus on privacy, Strata operates entirely locally without transmitting or storing data externally, ensuring that user dataLayer events remain secure.
