--- canonical: "https://www.softatlas.io/list/server-side-tagging" title: "Best Server-Side Tagging Platforms for 2026" locale: "en" market: "International" tool_count: 9 updated: "2026-10-12" --- # Best Server-Side Tagging Platforms for 2026 The 2026 field splits into three families. Hosts of server-side Google Tag Manager: Addingwell (monitoring first), Stape (lowest price, largest toolbox), Taggrs (European-only infrastructure), or hosting it yourself on Google Cloud. Platforms with their own technology: Commanders Act, JENTIS and Tealium EventStream. Elevar and Littledata do the job for Shopify stores without a tagging server. ## What this category covers Server-side tagging moves the work of marketing and analytics tags from the visitor's browser to a server you control. Instead of the browser calling Google, Meta and a dozen other vendors directly, it sends one stream of events to your server, which decides what to forward and to whom. In practice that server is most often a server-side Google Tag Manager container, and the main question becomes who runs it. Three reasons drive adoption. Browsers now cap the life of cookies set by scripts, at seven days in Safari, and a server answering from your own domain can set longer-lived ones. Ad platforms have built conversion APIs that expect events sent from a server. And a server gives a single place to enforce consent and strip personal data before anything leaves. One expectation needs correcting, and one of the hosts in this guide says it in its own documentation: server-side tagging does not, by itself, get past ad blockers. It reduces loss. It does not end it, and it never replaces consent. ## Methodology We assessed each tool on five criteria: (1) hosting, meaning regions, European residency and uptime commitments, (2) first-party setup and cookie resilience, (3) monitoring, logs and alerts, (4) compliance and consent, from certifications to consent features, and (5) how much setup work is left to your team. Assessments are based on each vendor's public product pages, pricing pages, documentation and trust pages, read in October 2026, and on Google's own documentation for the self-hosted option. Prices are published list prices at that date, in the currency the vendor displays. Pricing is described rather than scored. Tools are grouped by family (hosts of server-side Google Tag Manager, platforms with their own technology, e-commerce specialists) and listed alphabetically within each family; the order is not a ranking. Vendors can suggest an entry or a correction; entries are written and scored by Soft Atlas from public sources, and no placement is paid. Last updated October 2026. ## The tools ### 1. [Addingwell](/addingwell.md) Addingwell is a French host of server-side Google Tag Manager, based in Lille and acquired by the consent management company Didomi in April 2025. Its angle is that hosting is the easy part and knowing whether your tags still work is the hard one. The product monitors tag health, data and cookies, raises alerts for a drop in volume, a hole in the data, duplicated events or a failed tag, and shows the consent status of each tag fired. Logs can be sent to BigQuery on request. The infrastructure is Google Cloud, multi-region on paid plans, and on the Enterprise plan the container can run inside your own Google Cloud organisation. First-party setup goes through a reverse proxy, by path or by subdomain, configured with support, and Cookie Restore keeps identifiers for 13 months. Pricing is pay-as-you-go in euros: 100,000 requests free, then **€90 a month for 2 million**, €190 for 10 million and €390 for 25 million. Customers include Decathlon, Club Med and Yves Rocher. - **Strengths:** the strongest monitoring and alerting among the hosts; consent status per tag; option to run in your own cloud; clear overage pricing; case studies with large European retailers. - **Limitations:** no security certification is listed (controls are described as aligned with ISO 27001); the site quotes three different uptime figures and publishes no SLA text; reverse proxy, multi-region and cookie restore are missing from the free plan; a container already running on Google Cloud cannot be linked. ### 2. [Self-hosted sGTM on Google Cloud](/google-cloud.md) The baseline every host is compared with is doing it yourself. Google documents the setup and recommends Cloud Run, with a minimum of two instances to avoid losing data during an outage. Google puts each server at about $45 a month, so a production setup **starts near $90** and scales from there: two to ten servers handle roughly 35 to 350 requests per second. What you take on is the operation. You maintain the Google Cloud project and its billing, a separate preview server, and the updates of the tagging server, which carry security fixes and are applied by redeploying. Request logging is on by default and, Google warns, can incur significant charges above about a million requests a month. - **Strengths:** no intermediary between you and your data; full control of regions and scaling; costs documented by Google; nothing to migrate later. - **Limitations:** more expensive than a managed host at low volume; updates, monitoring and logging costs are yours; no cookie restoration or ad-blocker tooling included; needs cloud engineering time. ### 3. [Stape](/stape.md) Stape, self-funded and founded in 2021, is the default choice for most teams that host server-side GTM, and claims more than 200,000 clients. The entry price explains part of it. There is a free plan with 10,000 requests, then per container **Pro costs $20 a month for 500,000 requests**, Business $100 for 5 million and Enterprise $200 for 20 million. Global hosting runs on Google Cloud; EU hosting runs on the French provider Scaleway through an Estonian entity, with locations in France, Italy, the Netherlands and Poland. Around the hosting sits a long list of add-ons that Stape calls power-ups: a Custom Loader that changes script paths to resist ad blockers, a Cookie Keeper that restores cookies capped at seven days for up to 13 months, an anonymizer, bot detection, a data store. Stape also sells gateways, a simpler product for a single ad platform from $8 a month. It holds ISO 27001 and SOC 2 Type II, and publishes a 99.95% SLA. - **Strengths:** lowest entry price in this guide, with a free plan; EU hosting on a European provider; the widest set of add-ons; ISO 27001 and SOC 2 Type II; a published SLA. - **Limitations:** logs start at Pro and monitoring with alerts at Business; requests include script loads, previews and bots, and a container is paused at 110% of its limit unless auto-upgrade is on; a container's location cannot be changed later; the tagging itself remains your work in GTM, and setup by Stape is a paid service from $1,100. ### 4. [Taggrs](/taggrs.md) Taggrs is a Dutch host founded in 2022 whose selling point is where the servers are: its own infrastructure on the European provider UpCloud, with no Google infrastructure involved. For a company whose legal team objects to American cloud providers, that is the whole argument. It holds ISO 27001:2022, certified by DEKRA. The feature set follows Stape's closely: an Enhanced Tracking Script that replaces the GTM snippet and masks requests against ad blockers, Cookie Recovery on every plan, click ID recovery, a data enricher, a consent graph, and apps for Shopify, WooCommerce, Magento and other shop systems. Prices are in euros: free up to 10,000 requests a month, **Basic €25 for 750,000**, Pro €65 for 3 million, Ultimate €145 for 10 million. - **Strengths:** European infrastructure outside the large American clouds; ISO 27001 certification; cookie recovery on all plans; public pricing with a free plan; live chat support on every plan. - **Limitations:** the site contradicts itself on server locations (European by default in one place, distributed around the world in another) and publishes no current list; no public uptime commitment below the Enterprise plan; when a plan's limit is reached, data stops being forwarded unless automatic upgrade is on; multi-domain needs Pro; no refunds. ### 5. [Commanders Act](/commanders-act.md) Commanders Act is a Paris company that started in the early 2010s as TagCommander and has grown into a platform: an enterprise tag manager with server-side delivery, its own consent management platform, a customer data platform and, since it acquired Adloop in 2023, attribution. It reports more than 500 customers, among them AXA, Carrefour, Crédit Agricole and Leroy Merlin. It does not ask you to leave Google Tag Manager. A bridge template lets a team keep its existing GTM setup and send events to Commanders Act's servers, which then feed more than 100 server-side destinations, including the conversion APIs of Google, Meta, Amazon, TikTok and Snapchat. First-party collection can run through a WAF proxy, the method it recommends, a DNS record, or an on-premise proxy, and a feature called Phoenix recreates first-party cookies shortened by Safari. **Data centres are in the European Union.** - **Strengths:** tag management, consent and customer data in one platform; a built-in consent platform supporting IAB TCF and Google Consent Mode; several first-party options, on-premise included; works alongside GTM; European data centres. - **Limitations:** no public pricing, sales-led; first-party setup requires WAF or DNS work; a company-level ISO 27001 or SOC 2 certificate is not listed on its site, only its hosting provider's; built for large organisations. ### 6. [JENTIS](/jentis.md) JENTIS, founded in Vienna in 2020, replaces the tag manager rather than hosting Google's. One container handles client-side and server-side tags, with more than 100 connectors including GA4, Google Ads, Meta's Conversions API, TikTok and Adobe Analytics. Cookies are set in the HTTP response from your tracking server, under your own domain, and a user identifier can last up to two years. Its distinctive features are about consent. **Essential Mode** captures non-consented traffic in pseudonymised form. Synthetic Users builds consent-aware synthetic profiles from first-party data, meant to fill the gaps that refusals leave in marketing platforms. Privacy controls decide what each destination receives. JENTIS is ISO 27001 certified, connects to the main consent platforms (OneTrust, Usercentrics, Cookiebot, Didomi), and shows The Washington Post, Société Générale and Santander among the logos on its site. - **Strengths:** privacy controls per destination; pseudonymised capture of non-consented traffic; long-lived first-party identifiers; ISO 27001; a health centre that monitors tag execution. - **Limitations:** no public pricing; adopting it means moving off Google Tag Manager, although both can run in parallel during migration; its pages disagree on hosting, EU only in the FAQ and EU or US on the pricing page; no consent banner of its own. ### 7. [Tealium EventStream](/tealium.md) Tealium, founded in San Diego in 2008, is the incumbent of enterprise tag management, and EventStream API Hub is its server-side layer: it collects events, transforms them and forwards them to connectors without saving the data to disk. It sits beside Tealium's own tag manager, iQ, and its customer data platform, and the company counts more than 1,300 integrations across tags, connectors, warehouses and conversion APIs. The security record is the longest in this guide: **ISO 27001, 27701 and 27018, SOC 2 Type II and HIPAA**, with a choice of hosting location. Consent integrations enforce the signals of external platforms such as OneTrust, Didomi and Usercentrics. A template lets a site that runs Google Tag Manager post its data layer to Tealium, so the two can coexist. - **Strengths:** a mature enterprise platform; the widest catalogue of integrations; extensive certifications; the customer chooses the hosting location; a path to a full customer data platform. - **Limitations:** no public price for the tier that contains EventStream; first-party domains must be enabled by an account manager and do not support the Google Tag Manager integration; implementation is a separate services engagement; oversized for a team that only needs server-side tagging. ### 8. [Elevar](/audiense.md) Elevar is the best-known server-side tracking app for Shopify. Its ownership has changed: Buxton acquired it in 2024, and since July 2026 the product is sold as Audiense Online, with the old site redirecting to Audiense. The principle is unchanged. A prebuilt data layer captures clicks, carts and checkouts, and Elevar's servers send the events to more than 35 server-side destinations, Meta, Google Ads, TikTok and Klaviyo among them. Google Tag Manager is optional. On Shopify, requests go to the same subdomain as the storefront, and a server-set cookie identifies returning visitors for a year. Pricing follows order volume: **Core at $225 a month for 2,000 orders** and two destinations, Advanced $650 for 10,000 orders and four, Premium $1,250 for 30,000 and ten. Installation by Elevar costs $1,000. - **Strengths:** built for Shopify, with no tagging server to run; conversion monitoring included; identity resolution on every plan; public pricing; a 15-day trial. - **Limitations:** you cannot use your own servers; destinations are capped by plan, and an extra one costs $125 a month; hosting is in the United States and EU hosting is not documented; the terms allow fees to rise by up to 10% a year; the brand is in the middle of its move to Audiense. ### 9. [Littledata](/littledata.md) Littledata is a Shopify app from a UK company started in 2015. It combines a theme script with Shopify's webhooks, so that when a browser blocks the script, the order still reaches the destinations from Littledata's servers. The destinations are fewer than Elevar's but cover the essentials: GA4, Google Ads, Meta, Klaviyo, TikTok, Microsoft Ads, Pinterest, Segment and Attentive. Google Tag Manager is not required. The pricing has a pay-as-you-go entry: **Flex at $0.35 per order**, then Scale at $199 a month for 1,500 orders and Plus at $990 for 10,000, with 20% off on annual billing and a 30-day trial. - **Strengths:** the quickest setup in this guide; a webhook fallback when scripts are blocked; a pay-per-order entry plan; a 30-day trial. - **Limitations:** Shopify checkout only; data is hosted in the United States and, by the company's own statement, never leaves it; no security certification found on its site; a short list of destinations.
