Here are the two Chrome Extensions I’ve written.

  • GTM Sonar - Debug your on-site JavaScript to see if it’s compatible with the event listeners Google Tag Manager leverages

  • Internalize for Google Analytics - Send a Custom Dimension hit at the click of a button. This tool is intended to annotate traffic in a certain way, letting you filter it out or process it in any way you choose

GTM Sonar is especially useful for debugging potential problems with interfering JavaScript.

Feedback

Feel free to send me any feedback relating to the tools. I don’t do extensive testing, nor are the tools especially optimized performance-wise. These are issues I would love to tackle had I more time, but I’m really grateful for any ideas, feedback, or criticism you might want to throw my way.
