Overview

Product summary

Review the store description, core capabilities, and common use cases.

We’re grateful for your feedback—we've listened and are moving the functionality of Tag Assistant Companion into the original Tag Assistant extension and are retiring this extension. The original Tag Assistant extension now supports features from both the original and companion extensions, including in-page debugging and advanced functionality on tagassistant.google.com.

Please install the Tag Assistant extension. If you have both the original and companion extensions installed, the companion extension will be automatically uninstalled in the coming months.

AI product read

Google Tag Manager and gtag.js debugging companion that connects to Tag Assistant web app

Helps developers troubleshoot installation issues with Google Tag Manager containers and gtag.js tracking implementations on websites

1. Install extension and navigate to a website with GTM/gtag.js 2. Extension content scripts capture tag events (container starts, gtag hits, memos) 3. Open side panel which embeds tagassistant.google.com 4. Debug data is streamed from page to side panel via message passing 5. Use Tag Assistant web app interface to troubleshoot tag implementation issues

Target users: Web developers / Digital marketers / Google Tag Manager implementers / Google Analytics specialists

Extension is being retired - functionality being merged into original Tag Assistant extension
Cannot confirm exact authentication requirements of tagassistant.google.com without testing the live service
Most source files are compiled/minified making detailed analysis challenging

Monetization

No paid features detected

No evidence of paid features found in the extension source code. No payment processing, subscription checks, premium tiers, Stripe references, upgrade prompts, or feature gating detected. Google Tag Assistant is a free developer tool.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension embeds tagassistant.google.com in an iframe for the core debugging workflow. The background script handles /login/success redirects from tagassistant.google.com and passes authuser parameters (sw/background_script_bin.js line 35-36: handling login/success path with authuser parameter). The side panel loads tagassistant.google.com/embedded/side_panel which is a Google service requiring authentication. The extension itself does not implement its own login system but relies on Google authentication at the destination service.
