TMI is a free tool enabling you to inject your Google Tag Manager™ container snippet onto any page of any site without the need for code changes!

All you need is your GTM™ container ID.

This will be useful if you...

- are considering using GTM™ as a tag management system and would like a test drive without actually deploying the GTM™ container on your site.

- have a long wait for the snippet to be implemented and would like to pre-configure your container ready for when this change happens.

TMI will allow GTM's™ preview and debug mode to function as normal, allowing you to fully configure and test your container prior to releasing the container snippet.


- Add the extension to Chrome and ensure that TMI is listed in your Extensions and enabled here... chrome://extensions/
- Click the icon in your Chrome interface and enter your GTM™ container ID in the format GTM-123456
- Refresh any tab to see your container injected

The container snippet is now active on any site you visit within that browser session.

- To stop the container from being injected, simply click the TMI icon again in Chrome and select DEACTIVATE

- You can restrict TMI to injecting GTM™ on certain domains using an exact and regular expression match.

- You can also push variables to the data layer prior to the container loading to test ecommerce implementations and other taxonomy.
