Jitsu

Jitsu is an open-source event data collection and integration platform that enables developers to capture behavioral data from websites, apps, and other sources and stream it in real time to data warehouses such as Snowflake, BigQuery, Redshift, and ClickHouse. The platform is a self-hosted, open-source alternative to Segment, offering a JavaScript tag for web tracking, an HTTP API for server-side events, and a suite of pre-built connectors for syncing data from external SaaS services. Jitsu provides a serverless functions runtime that allows users to transform, filter, and enrich events before they are stored, and includes a built-in identity stitching capability that constructs a real-time user identity graph.
