Google Tag Manager | cside docs

GTM is for testing only

Google Tag Manager does not guarantee script load order, so other scripts may execute before cside can intercept them. For production, use direct script installation to make sure cside loads first.

cside is available as a community template in the GTM Template Gallery. This is the fastest way to try cside on your site without touching any code.

Setup

Add the cside template

Open the GTM Template Gallery and search for cside. Click Add to workspace to install the template into your GTM container.

Create a tag

In your GTM workspace, create a new tag using the cside template. Set the trigger to All Pages so cside monitors every page on your site.

Publish your container

Click Submit in GTM to publish the changes. Visit your website - you should see script traffic appear in the cside dashboard within seconds.

Moving to production

When you’re ready for production, switch from GTM to a direct integration method. This guarantees cside loads before any other scripts on the page:

Manual script tag - Works with any framework
Next.js package - @cside.dev/next
Vite plugin - @cside.dev/vite
CLI tool - For static sites
