If you’ve noticed your conversion numbers dropping over the past year without any clear reason, you’re not alone. Cookie deprecation, iOS 14+ privacy updates, and ad blockers have fundamentally broken how client-side tracking works. When tracking happens in a user’s browser, it’s vulnerable to browser restrictions that can cause significant data loss before your analytics platform ever sees it.
Server-side tracking approach fixes much of this. Instead of sending event data directly from the browser to ad platforms like Meta or Google, events flow from the browser to the server container. Clean and enriched data is then forwarded to your marketing tools. This approach bypasses many browser limitations and keeps your data collection accurate.
This article covers 7 leading GTM Server-Side Tracking Services providers that manage the configuration and ongoing maintenance of the setup, with some offering additional features designed to further enhance performance, data accuracy, and privacy compliance.
List of Top GTM Server-Side Tracking Services
1. Stape
Stape’s GTM server-side tagging service is used by over 200,000 accounts worldwide, which is quite a significant number. If you have already worked with Google Tag Manager, you’ll feel almost at home – Stape handles the servers, autoscaling, and security in the background while you keep doing all the familiar GTM-related things.
Getting started with this company is surprisingly quick. You create a server-side container in GTM, connect it in Stape’s dashboard, pick a region close to your audience (EU or US), and get a working tagging server endpoint in minutes, without technical complexity.
On top of that, Stape offers various power-ups that extend the setup’s functionality, among which there are:
- Custom Loader: to make tracking scripts more resistant to restrictions and ad blockers;
- Cookie Keeper: to extend first-party cookie lifetime;
- Stape Store and sGTM templates: to sync and enrich customer data across sessions.
The company offers free services to businesses with low traffic (less than 10,000 monthly requests), and its payment plans start at $17/month. It is a great deal, compared to other similar service providers, whose invoices can easily go beyond $100 or even $200 per month.
2. Elevar
Elevar started as an ecommerce tracking and attribution platform heavily focused on Shopify merchants around 2017-2018. The platform has since evolved into a comprehensive solution that combines data layer management, server-side tagging, and conversion tracking specifically tailored for online stores.
The Elevar server-side tagging offering works through a Shopify app combined with pre-built GTM templates and managed server infrastructure, typically running on Google Cloud Platform. This setup centralizes your connections to Google Analytics 4, the Facebook Conversions API, and other marketing pixels without requiring you to build everything from scratch.
3. Tracklution
Tracklution is a European-focused server-side tracking and data infrastructure provider that emphasizes GDPR compliance and first-party data ownership. The company positions itself as more than just hosting, offering strategic guidance on how to structure tracking for privacy-conscious markets.
The platform typically uses GTM server-side tagging combined with additional middleware to route data to various destinations. This includes Google Ads, the Facebook Conversions API, TikTok Events API, and CRM systems. The middleware layer handles transformations and ensures that events arrive at each platform in the expected format.
4. Usercentrics
Usercentrics is primarily known as a Consent Management Platform, founded in 2018 and widely deployed across EU websites for GDPR compliance. The distinctive angle of their server-side tracking offering is that it builds directly on top of their consent management capabilities.
The core value proposition is ensuring that your server container and conversion APIs respect the same consent choices captured in the browser-side consent banner. This creates a unified consent mode implementation where server-side tags only fire when users have actually agreed to analytics or marketing categories.
5. AdPage
AdPage started as a Dutch-origin landing page and funnel builder that has since expanded into privacy-friendly tracking and server-side event forwarding systems. The platform targets marketers running paid campaigns who want an all-in-one solution for building pages and tracking conversions.
Their server-side tracking is designed for marketers hosting landing pages and funnels directly on AdPage rather than external websites. This tight integration allows the platform to automatically capture and forward events without complex tag manager server-side configuration.
6. OwnTag
OwnTag positions itself as a data ownership platform where brands run first-party tracking through their own subdomain and infrastructure while still using GTM server-side concepts. The messaging centers on control and transparency over your data stream.
Data sovereignty is a core focus for OwnTag. It offers storing logs in chosen regions, often within the EU, along with transparent data paths and tools to export or delete user-level data on request. This appeals to organizations subject to data residency requirements or those simply wanting more control over their tracking infrastructure.
7. Jentis
Jentis is an Austrian-founded server-side tracking and data capture platform that has been active since the mid-2010s, now serving large enterprises and publishers across Europe. The platform goes beyond basic GTM server-side hosting by offering its own tag management layer, data pipelines, and consent-aware tracking logic.
Integration options extend to GA4, Meta CAPI, Google Ads, and custom data warehouses like BigQuery or Snowflake. This flexibility makes Jentis suitable for organizations with complex analytics stacks that need to route the same event data to multiple destinations.
