Full Answer
The Google Cloud dependency is a consequence of how GTM server-side was designed, not a technical necessity for server-side tracking itself. When Google launched server-side tagging, it built the system to run on Cloud Run — Google's serverless container platform. This made architectural sense for Google, but it transferred significant infrastructure responsibility to store owners who had no prior relationship with cloud computing.
The practical burden is substantial. Setting up GTM server-side on Google Cloud requires creating a Cloud project, enabling billing, provisioning Cloud Run instances, configuring a custom first-party domain via DNS, and managing scaling policies. For a typical WooCommerce store owner who chose WordPress precisely because it abstracts away server complexity, this is a category mismatch.
Hosting providers like Stape and TAGGRS partially solve this by wrapping Cloud Run in a managed layer, but the underlying architecture remains — you are still running Google Cloud infrastructure, still subject to its pricing model, and still dependent on GTM's container-based tag configuration. The abstraction reduces setup friction without removing the fundamental architectural dependency.
Server-side tracking solutions built natively for WordPress bypass this entirely. They run as dedicated first-party servers on standard hosting infrastructure, capture events directly from WooCommerce hooks, and route data to ad platforms without requiring GTM containers, Cloud Run instances, or Google Cloud billing.
