jitsu
Jitsu is an open-source Segment alternative. Fully-scriptable data ingestion engine for modern data teams. Set-up a real-time data pipeline in minutes, not days
The Lens
Jitsu is an open-source event collection and data pipeline tool. It captures events from your web and mobile apps and streams them directly to your data warehouse or analytics tools. Segment-style routing, warehouse-first design. MIT-licensed.
Self-hosted via Docker. Simpler to operate than RudderStack for teams with fewer destination needs. The warehouse connector is the strong suit: Snowflake, BigQuery, ClickHouse, Redshift. SDK support covers JavaScript, Python, and mobile.
Teams that want to capture web events and land them cleanly in a warehouse without paying Segment's per-MTU pricing get immediate value here. Less useful if you need 200+ marketing-tool destinations.
The catch: Jitsu is leaner than RudderStack or Segment, which means fewer pre-built connectors. If your use case is warehouse-only, that is fine. If you need Salesforce, HubSpot, or ad platform integrations, the connector library gets thin fast.
