GTM server-side hosting is a crowded market. Stape leads with 200,000+ accounts and power-ups like Custom Loader and Cookie Keeper. TAGGRS offers similar functionality with competitive pricing. Addingwell provides fully-managed tagging servers. Tag Concierge positions on affordability. Taggian emphasizes EU infrastructure and pay-as-you-go pricing. All share the same limitation: they host the server but you still configure GTM tags, triggers, variables, and debugging. The hosting is commoditized; the expertise requirement is not.
