# Jitsu

Open-source Segment: capture events, script the pipeline, warehouse the rest.

**Replaces:** Segment

**Tier:** Medium

## Problem

Segment bills monthly tracked users and then sells Unify. Jitsu is the catalog OSS Segment alternative — ingest, transform, warehouse, no MTU invoice.

## Stack

- [Jitsu](https://github.com/jitsucom/jitsu) — Open-source Segment alternative

## Estimated SaaS cost saved

| You stop paying | Typical / year | Self-host instead |
|---|---:|---|
| Twilio Segment Connections | $2,400 | Jitsu self-host |

**About $2,400 / year** on a small team, before you count lock-in.

## Deploy on Railway

Placeholder: Jitsu + Postgres (or ClickHouse). Replace the Segment snippet with Jitsu's. Warehouse later.

## AGENT_PROMPT

```
Replace Segment with Jitsu.

- Deploy Jitsu. Point the existing analytics snippet at it. Keep one destination (warehouse or webhook) working.
- Do not rebuild every Segment destination on day one. Write AGENT_PROMPT.md and a note on MTU vs hosting.
```

## FAQ

### Is this a full CDP?

It is the pipeline: collect, transform, send. Audiences and journeys are a different product. Most teams only needed the pipeline.
