What it is
Addingwell provides server-side tagging built on Google Tag Manager Server-Side, designed to recover advertising signals affected by ad blockers, browser restrictions, and cookie deprecation. Its monitoring tools track tag events, alert users to problems, and provide insights into sent-data quality and cookie integrity across browsers. Infrastructure includes multiple regions, CDN, JavaScript asset proxying, and reverse-proxy capabilities for managing data flows. Documentation describes server-side event delivery to Google Analytics 4, Google Ads, and Meta, plus a separate Microsoft UET Conversion API tag. Didomi-backed consent monitoring can display consent attached to each request in real time. Addingwell offers a free plan with 100,000 requests and one-region infrastructure. Pay as you go costs €90 a month and includes 2,000,000 requests and multi-region infrastructure. Unused requests do not roll over; additional requests are calculated at the end of the billing cycle and added to the invoice. Setup requires DNS records for a tagging subdomain, with propagation taking five minutes to one hour. The service is available through the web and API for websites and Google Tag Manager Server containers.
