Server-side Google Tag Manager, hosted in the EU

Tracking Hippo gives you a fully managed server-side GTM environment without the usual headaches of self-hosting, metered billing, or data leaving Europe.

Your tracking runs on EU-based infrastructure across multiple regions, so your first-party data stays close to your users and inside GDPR boundaries.

Why teams switch to Tracking Hippo

  • Flat, predictable pricing. One price, no request caps. Your bill never spikes because a campaign went well.
  • Own your first-party data. Move tracking off the browser and beat ad blockers, ITP, and cookie restrictions.
  • EU data residency by design. Infrastructure and processing stay in Europe, making GDPR and Consent Mode v2 far easier to defend.
  • Built to scale. Multi-tenant Kubernetes across EU regions keeps latency low and uptime high, whether you send thousands or millions of events.

Works with your existing stack

Connect GA4, Meta CAPI, Google Ads, and any other server-side tag with a first-party setup. Bring your existing GTM container and point it at Tracking Hippo in minutes.

Who it's for

Agencies, marketers, and in-house teams who want reliable server-side tracking, clean data, and a bill they can actually predict.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

Possible disadvantages of Tracking Hippo

  • Limited Customization
    While Taggian offers many features, there may be limitations in terms of customizing certain aspects to fully fit unique user needs.
  • Pricing Structure
    Some users may find the pricing structure to be on the higher side, especially for small businesses or individual users with limited budgets.
  • Learning Curve for Advanced Features
    Although the basic interface is user-friendly, mastering the more advanced features might require some time and effort.
  • Dependence on Internet Connectivity
    As an online platform, Taggian requires a stable internet connection to function optimally, which could be a drawback in areas with poor connectivity.

Analysis of s3-lambda

Overall verdict
