## What it is
RudderStack's open-source event streaming server, a privacy- and security-focused Segment alternative written in Go. It collects customer event data from websites, apps, and backends via SDKs, then routes it in real time to data warehouses (BigQuery, Redshift, Snowflake) and 200+ business tools.

## Use cases
- self-host a Segment alternative for customer event tracking
- stream clickstream and product events to Snowflake, BigQuery, or Redshift
- route customer events to CRMs, ad platforms, and analytics tools
- build a privacy-focused customer data pipeline without vendor lock-in
- run reverse ETL to sync warehouse data back to business tools
- collect events from web, mobile, and server-side SDKs into a data warehouse

## When to choose
- you need an open-source, self-hosted CDP with full data control
- you want to replace Segment while keeping its API-compatible SDKs
- you need real-time event streaming into warehouses and 200+ destinations
- privacy, security, and data residency are priorities for your event data

## When to avoid
- you need a fully open-source license - the server uses Elastic License v2, not OSI-approved
- you only need batch ELT from SaaS apps to a warehouse without event streaming
- you want a managed SaaS CDP without operating your own infrastructure
- your team cannot run and scale a Go server with backing stores like Postgres and Redis
