## Description

Jitsu is an open-source customer data platform designed to orchestrate event data pipelines. It captures, transforms, and routes behavioral data from web and server sources into data warehouses and analytics tools, providing a unified infrastructure for managing event streams.

The platform distinguishes itself through its focus on self-hosted, containerized operations that grant users full control over their data security and privacy. It features a robust identity resolution engine that stitches disparate user identifiers into persistent profiles across sessions and devices, alongside programmable transformation logic that allows for real-time data enrichment and payload modification. By utilizing proxy-based collection and custom tracking domains, it enables organizations to maintain data visibility while bypassing common browser-level tracking restrictions.

The system covers a comprehensive range of data engineering capabilities, including reliable event queuing, automatic schema management, and batch processing for high-throughput ingestion. It supports complex workflows such as audience segmentation, CRM synchronization, and real-time streaming to various analytical databases. Integrated monitoring, debugging tools, and programmatic management interfaces facilitate the maintenance of these pipelines within private infrastructure.

The project is distributed as a containerized service, supporting deployment across diverse cloud and on-premise environments including Kubernetes.
