TAGGRS is a European first-party performance platform that helps organizations regain confidence in their marketing data. We are the central hub for data before it is distributed to analytics, advertising and marketing platforms, which puts us at the intersection of compliance and performance. We operate within privacy regulations while maximizing the quality and quantity of the data that you collect.

Built around Server-side Tracking and Google Tag Manager, TAGGRS reduces the data loss caused by browser restrictions, ad blockers and evolving privacy rules. Better consented first-party data means marketing and financial decisions you can trust, campaigns you can optimize with certainty and numbers that hold up.

Reliable data is also the fuel for modern marketing technology. By improving the input for analytics tools, attribution solutions and advertising algorithms, TAGGRS strengthens AI-driven models and drives stronger campaign results and higher return on ad spend.

Because TAGGRS uses Google Tag Manager, it works with any CMS, consent management platform or marketing stack. If Meta is your priority, our Meta Conversions API Gateway is a fully managed alternative that connects your conversion data directly to Meta, with real-time insight into Event Match Quality.

What you get: - An automated base setup that shortens time to value - Tracking analytics that shows how much data you collect and how good it is - Monitoring that instantly detects data loss and downtime - Proactive diagnostics based on patterns we see across our network - Tracking complexity handled in our backend, so it stays simple for you - Top tier support - Compliance, transparency and data sovereignty as the default

We believe maximizing data input maximizes performance output. With constant change in privacy, tracking, advertising and AI, optimizing your data is a continuous responsibility, and TAGGRS is the platform built to support it.

With TAGGRS, you rebuild trust in your data.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
