Jitsu

Jitsu is an open-source customer data platform designed to capture behavioral event data from websites, mobile applications, server environments, and CRMs. It provides a data warehouse-first architecture that streams clean, structured event data directly into destinations like Snowflake, BigQuery, Redshift, and ClickHouse in real time.

The platform is built for developers, data engineers, and technical growth teams looking for self-hosted or cloud-managed data ingestion pipelines without vendor lock-in. It features pre-built connectors, JavaScript runtime execution for event transformation, and compatibility with the Segment API to simplify migrations.

Key features

• Real-time event streaming: Streams user behavioral data from applications directly to data warehouses and downstream tools in real time.
• Jitsu Functions: Executes custom JavaScript functions to modify, filter, or enrich events before storing them in destinations.
• Identity stitching: Constructs real-time identity graphs to resolve and unify user profiles across touchpoints.
• Custom domains: Allows event collection scripts to run on custom subdomains to mitigate ad-blocker tracking restrictions.
• ClickHouse integration: Includes a provisioned ClickHouse setup alongside support for traditional data warehouses.
• Connector catalog: Connects with over 600 connectors and destinations for syncing data across SaaS applications.
