What our analysis found

Tag Assistant, used by 3,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can inject scripts into pages. It comes from a trusted publisher and was last updated in September 2026.

The extension is an official Google tool for debugging Google tags. All network communication stays within Google-owned domains (,, etc.). The permissions are required for its core functionality. The code does not contain data exfiltration to third parties, obfuscation beyond standard minification, or privilege escalation. The disclosed data collection categories are consistent with the extension's purpose and the privacy policy's coverage.

About this extension

The Tag Assistant extension works with Tag Assistant to help troubleshoot installation of gtag.js and Google Tag Manager.

Read the publisher’s full description

We’re grateful for your feedback—we've listened and will be updating and bringing back the on-page debugging experience. More exciting features are on the way. Tag Assistant helps you install and troubleshoot your Google tags, including Google Analytics, Google Ads, Tag Manager and more. When clicked, the extension displays the Google tags found on the page in a side-panel. Just navigate to any page, and Tag Assistant will tell you which tags are present. We will be adding additional diagnostics in the near future. The “Troubleshoot” button activates our debug mode using tagassistant.google.com. This advanced tool allows you to debug your website, including iframes, within a single session, providing detailed diagnostics to help you validate, diagnose, and resolve your implementation. Session data is available for review on tagassistant.google.com. COMING SOON: Step-by-step guidance to install tags on popular website builders. By installing this extension, you agree to the Google Terms of Service and Privacy Policy at https://www.google.com/intl/en/policies/.
