An Addingwell alternative, without a GTM container to maintain
Addingwell is a very good server-side Google Tag Manager hosting service. DataFirefly takes a different route: your events go straight to the conversion APIs of Meta, GA4, TikTok, Pinterest, Google Ads and Microsoft Advertising, with no GTM container to create, configure or maintain. Here is an honest comparison of the two approaches, so you can pick the one that fits your team.
sGTM hosting and direct CAPI are not the same job
Comparing Addingwell and DataFirefly starts with comparing two architectures. Neither is "better" in the absolute: they just don't ask the same work from your side.
Addingwell: hosting your server-side GTM container
Addingwell (a Didomi company) provisions and operates the infrastructure for a server-side Google Tag Manager container. You (or your agency) build the tracking inside it: clients, Meta CAPI tags, GA4, triggers, variables, debugging. Powerful and flexible, but the container's configuration and maintenance stay on your plate.
DataFirefly: direct CAPI, no container
DataFirefly receives events from your shop (PrestaShop module, WooCommerce or Shopware plugin, or a signed HTTP API) and dispatches them straight to the platforms' conversion APIs. The "container" simply does not exist: dispatch logic, deduplication and consent handling are carried by the platform, not by you.

| Addingwell | DataFirefly Server-Side | |
|---|---|---|
| Technical model | Hosting of a server-side Google Tag Manager container | Direct dispatch to conversion APIs (no GTM container) |
| Getting started | Create the container, configure clients, tags, triggers and variables: often with an sGTM agency or freelancer | Install the connector (PrestaShop, WooCommerce, Shopware) and paste one connection key |
| Ongoing maintenance | Container tags and templates to maintain as platforms evolve | API connectors maintained by DataFirefly, platform-side |
| Destinations | Broad: anything the GTM template gallery allows, configured tag by tag | Six destinations ready out of the box: Meta CAPI, GA4, TikTok, Pinterest, Google Ads, Microsoft Advertising |
| Multiple shops | Extra container: +€30/month; extra domain: +€10/month | Every shop on your account under one subscription, one invoice |
| Hosting | European infrastructure (French service, Didomi group) | Germany (Falkenstein, EU): explicit residency, GDPR by design |
| Diagnostics | Container and request monitoring | Event-by-event Inspector with personal data redacted |
| Entry price | €90/month for 1 million requests (tiers up to €1,190/month for 100M; overage billed per 100k) | €39/month (Starter): Growth €119, Scale €349 |
| Skills required | Server-side GTM: clients, tags, variables, debugging | No GTM skills: the client area is all you need |

When to pick one or the other: honestly
Addingwell is a good choice if…
Your team (or your agency) masters server-side GTM and wants the full flexibility of a container: custom tags, advanced data transformations, destinations beyond the classic e-commerce conversion APIs. You accept carrying the configuration and maintenance in exchange for that freedom.
DataFirefly is a good choice if…
You run a PrestaShop, WooCommerce or Shopware store, or an agency managing several shops, and you want to recover the conversions lost to ad blockers and ITP without becoming a GTM expert. Setup takes minutes with a connection key, six destinations are included, multi-shop comes with no per-container surcharge, and hosting is in Germany.

Frequently asked questions
Is DataFirefly a server-side GTM host like Addingwell?
No, and that is the main difference. Addingwell hosts a server-side Google Tag Manager container that you configure and maintain (tags, triggers, variables). DataFirefly sends your events straight to each platform's conversion API: there is no GTM container to create, configure or maintain.
Can I migrate from Addingwell to DataFirefly?
Yes. On PrestaShop, WooCommerce or Shopware, setup comes down to installing the official connector and pasting a connection key copied from your client area. You can run both solutions in parallel during the transition, then cancel the sGTM hosting once conversions are reporting correctly.
How does DataFirefly pricing compare with Addingwell?
DataFirefly starts at €39/month with all destinations and every shop on your account included. Addingwell starts at €90/month for 1 million requests to the container (pricing checked in July 2026), on top of which comes the time to configure and maintain the GTM container, often outsourced to an agency.
When is Addingwell a better choice?
If your team already masters server-side GTM and needs the full flexibility of a container: custom tags, advanced transformations, niche destinations through the template gallery: an sGTM host like Addingwell is a sound choice. DataFirefly targets merchants and agencies who want reliable server-side tracking without carrying that complexity.
Where is DataFirefly data hosted?
The DataFirefly dispatcher is hosted in Germany (Falkenstein, European Union). Personal data is redacted in the diagnostic tools, ingestion is HMAC-authenticated and tracking respects visitor consent: GDPR by design.
Server-side, without the container
Six destinations, native PrestaShop / WooCommerce / Shopware connectors, hosted in Germany. From €39/month, no commitment.
