In short
- Hosted server-side GTM with EU data residency by default

- Templates for Meta CAPI, GA4, TikTok, and consent integrations
- Best fit: EU and DACH brands wanting French / EU-hosted server-side tagging
What is Addingwell
Addingwell is a hosted server-side Google Tag Manager provider built in France with EU data residency as the default. Functionally similar to Stape: hosted containers, no DevOps burden, templates for the common destinations (Meta CAPI, GA4 server-side, TikTok Events, Pinterest CAPI). The differentiator is positioning, Addingwell leans harder into EU privacy compliance with a French DPA, no transatlantic data transfers, and clearer subprocessor disclosure than the US-headquartered alternatives.
Where Addingwell fits in 2026
Addingwell is the natural pick for European brands, especially DACH and France-headquartered teams, that need server-side tagging and want their data processor based in the EU under EU governance. The product itself is good rather than exceptional; the wedge is hosting jurisdiction and procurement-friendly compliance documentation.
The honest trade-off versus Stape: Addingwell’s templates and Power-Up-equivalent library are narrower. Teams that need exotic integrations may hit gaps Stape would have covered. For the standard stack (Meta CAPI, GA4 server-side, TikTok Events, consent stitching), Addingwell holds its own.
How Addingwell compares to alternatives
Versus Stape: Stape has the broader template library, wider region coverage, and longer product history. Addingwell wins on EU-native positioning and procurement story for European regulated buyers. Pricing is comparable. Versus self-hosted server-side GTM: Self-hosting on a French or German cloud provider gets you EU residency at lower cost but with full DevOps responsibility. Addingwell trades cost for managed infrastructure. Versus adtribute or a CDP: Different category. Addingwell runs the container; a CDP or attribution platform manages the event schema and routing decisions.
FAQ about Addingwell
How much does Addingwell cost?
Addingwell starts at €90/month for 2M monthly requests, with billing based on incoming requests only. That is roughly double Stape’s €50/mo entry tier but can work out cheaper at scale because outgoing requests don’t count.
Addingwell vs Stape, which is better?
Stape is cheaper at the entry tier and holds more compliance certifications (ISO 27001, SOC 2, HIPAA). Addingwell wins on EU-native positioning, agency white-label tooling, phone support on all plans, and the incoming-only billing model that scales better for high-volume multi-destination routing.
Who owns Addingwell?
Addingwell was acquired by Didomi in April 2025 for $83M. It now sits inside Didomi’s consent management and EU privacy stack, alongside its CMP serving 1,500+ enterprises.
Is Addingwell GDPR-compliant?
Yes. Addingwell is French-built with EU-hosted server containers, which is its main differentiator versus US-headquartered server-side GTM hosts. Data residency stays in the EU by default.
Do I need GTM knowledge to use Addingwell?
