Do you prefer integrated software debugging tools over using specialized browser extensions?

Google has introduced an Enable verbose logging option within the Tag Manager Preview mode. This update centralizes tag logs within the Tag Assistant Console tab for improved troubleshooting.

Why it matters

By consolidating logging data alongside other Preview mode metrics, Google aims to streamline the debugging process for users. This integration removes the previous reliance on the separate GA Debugger browser extension.

The new logging feature is currently restricted to the Tag Assistant table view within the Google Tag Manager platform. Users cannot yet filter logs by specific tag or template types.

Market Landscape

This move represents a broader industry trend of centralizing development tools within native platforms to improve efficiency. It marks a clear departure from the legacy dependency on the GA Debugger browser extension, positioning Tag Manager as a self-contained debugging environment.

Users can now debug tracking implementations more efficiently without switching between multiple browser extensions. While logs are currently static, this native integration simplifies the workflow for daily tag management tasks.
