Tracking Hippo is managed hosting for server-side Google Tag Manager. Paste your Container Config, point a CNAME at your tagging subdomain, and your container runs on EU-only infrastructure in Madrid or Amsterdam. First-party endpoints keep attribution intact where browser-side tracking degrades, and events are enriched server-side before forwarding to GA4, the Meta Conversions API and other destinations. Flat rate per container per month, 10 million requests included, no tiers, no DevOps.
