Is Addingwell an alternative to Stape?

Yes. Both are managed hosts for GTM server-side containers. The container behaves identically; differences are in tooling, pricing at your volume, and company footprint (Addingwell is French, which some EU procurement teams prefer).

Does Addingwell make my setup GDPR-compliant?

No host does. Compliance is decided by your container configuration: whether consent is forwarded and evaluated before tags fire, and what data each vendor receives.

How do I check that my Addingwell setup works?

Verify first-party script delivery and HTTP cookies in DevTools, confirm no vendor requests fire on refusal, and test that conversions are recorded once per vendor. Our free tracking checker covers the passive part automatically.

Addingwell: What It Is, and How to Verify Your Server-Side Setup

Last updated on July 30, 2026

Addingwell is a managed hosting platform for Google Tag Manager server-side containers, built by a French team. Like any managed host, it runs the infrastructure; the compliance and data-quality outcomes still depend entirely on how your container is configured.

What Addingwell is

Addingwell operates the infrastructure behind your GTM server-side container: you connect a subdomain, it runs and scales the container, and provides tooling around custom loader delivery, cookie handling and monitoring. It is a direct alternative to Stape and to self-hosting on cloud infrastructure.

A practical note from EU client projects: Addingwell being a French company with a European footprint regularly simplifies procurement and data-governance conversations with legal teams, which can matter as much as any technical feature.

Managed hosting changes where the work is, not what it is

Whoever hosts your container, the work that determines results stays the same: forwarding consent state into the container, conditioning every vendor tag on it, setting HTTP cookies server-side to survive Safari’s JavaScript cookie cap, and deduplicating events that leave from both the web and server containers.

In audits, the failure modes on Addingwell-hosted setups are identical to those on any other host: consent not forwarded, cookies still set client-side, and duplicate conversions from missing event identifiers. The host is rarely the problem; the configuration usually is.

The verification checklist

In a private window, before any consent choice: no vendor cookies in the Application tab, no vendor hits in the Network tab.
GTM script and hits load from your subdomain, and responses set HTTP cookies (visible in the response headers).
After refusing consent: still no vendor requests, from either container.
After accepting: run a test conversion and confirm each vendor records it exactly once.

Our free tracking checker automates the passive checks on any URL, and the Google Consent Mode checker validates the consent signal specifically.
