Jitsu

Jitsu is an open-source, self-hostable platform that captures event data from various sources and streams it in real time to a data warehouse. It positions itself as a fast, durable alternative to Segment with a warehouse-first approach and optional hosted deployment.

Collects events from websites, apps, emails, chatbots, and CRMs, and streams them to a data warehouse in real time. Setup is described as simple—add a tag or script to collect events, then map to a warehouse of choice (Snowflake, BigQuery, Redshift, Postgres, MySQL, or Clickhouse). Includes a JavaScript runtime for Jitsu Functions to modify, filter, or augment events before storage, and provides features like automatic user identity stitching and custom domains. Available deployment options include self-hosted on your own infrastructure or hosted by Jitsu (Cloud/Private Cloud/On Premise).

Who it’s for: Organizations needing real-time event data integration into data warehouses, especially teams preferring self-hosted/open-source solutions or those seeking a warehouse-first data pipeline with flexible deployment.
