Adlatrr

Adlatrr is an open-source software project that provides tools for collecting, normalizing, and analyzing latency data in digital advertising. It is designed to help advertisers, publishers, and ad-tech vendors evaluate how quickly ads are served, loaded, and rendered across networks, devices, and geographies. The project emphasizes observational analytics over prescriptive optimization.

The core of adlatrr comprises a modular architecture with data ingestion adapters, a core analytics engine, and a visualization layer. It supports batch and streaming data, handles multiple data formats such as JSON and columnar stores, and offers pluggable exporters to dashboards, notebooks, or data warehouses. Metrics typically focus on stages of ad delivery, including request time, server response, and render latency, along with percentile distributions and error rates. The design encourages extending the system with new data sources, metric definitions, and visualization formats to fit existing pipelines.

Data handling in adlatrr centers on aggregating disparate latency signals into a coherent model. It provides tooling for data normalization, time-alignment, and aggregation across dimensions such as network, device, geography, and ad product. Privacy considerations are addressed through guidance on data minimization and anonymization to mitigate exposure of user-level information while preserving aggregate performance insights.

Usage and ecosystem aspects include instrumentation of ad delivery pipelines to emit latency events, ingestion from ad servers and exchanges, and generation of dashboards or reports for performance monitoring. Adlatrr is typically maintained by a community of contributors and released under an open-source license, with documentation to assist setup, data modeling, and best practices.
