What is Jitsu?

Jitsu captures events through JavaScript, mobile and server SDKs and sends them in real time to destinations: data warehouses such as ClickHouse, BigQuery, Snowflake or PostgreSQL, and other tools you use. It covers the same ground as Segment, but because it is MIT-licensed and self-hostable, the data pipeline stays under your control. Functions written in JavaScript can transform or filter events on the way, and an MCP server lets AI assistants work with your setup. Jitsu Cloud is the hosted option.

Good fit if

  • You want Segment-style event collection without per-event vendor pricing.
  • Your analysts work in a warehouse and need clean event data there.

Look elsewhere if

  • You want ready dashboards instead of a pipeline: PostHog or Umami.
  • You want a small install: the self-hosted stack runs about 17 services, including Kafka, ClickHouse, MongoDB and PostgreSQL.

Before you adopt it

Jitsu is MIT-licensed, with no paid parts in the repository, and a Helm chart is included. One developer writes about 90% of the recent code.
