Created a Free Tool to Instantly Check if Your GA4 or GTM Are Implemented Server-Side or Client-Side (among many other things)

I’ve been working on a project that I think could be really useful for this community, especially if you’re dealing with a lot of tracking setups or audits.

I built the Tracker Checker, a free Chrome extension that helps you quickly see:

  • GA4 & GTM Implementation: It instantly checks if your Google Analytics 4 or Google Tag Manager setup is server-side or client-side. No more guessing or digging through scripts—you’ll know right away!
  • Detailed Tracker List: Tracker Checker also scans the site and shows you all the trackers that are running, like Google Ads, Facebook Pixel, TikTok Pixel, LinkedIn Insights, and more.
  • Google Consent Mode Insights: Easily check which version of Google Consent Mode is active (v1 or v2) and verify if your consent settings are working as expected.
  • External Resources Check: While it’s not a full performance monitor, it helps you spot external resources that could be affecting page speed or loading issues.

Why I Made It:

I was frustrated with how much manual work it takes to verify if tracking setups are working as expected. Whether you’re auditing a client’s site or managing your own, I wanted a tool that simplifies this process, and the Tracker Checker does just that. It’s free, easy to use, and doesn’t require an expert to understand the results.

You can get it here on the Chrome Store: Tracker Checker for free. If you try it out, I’d really appreciate any feedback or suggestions for improvements.

I hope it saves you some frustrations.

Hi there!

Thanks for sharing this! We really appreciate your input into this community. I checked it out and it’s really easy to use and informative, especially the consent view :slight_smile: Are you planning on adding Piwik PRO to the list of recognized trackers? (and recognized cookie banners)
