Build real‑time, privacy‑first customer data pipelines with RudderStack.
RudderStack lets developers collect, transform, and route event data from any source to warehouses and tools, offering warehouse‑first architecture, high availability, and fine‑grained privacy controls.
RudderStack is a developer‑focused Customer Data Platform that enables you to ingest events from websites, mobile apps, and SaaS services, then activate that data in your data warehouse or downstream tools. It treats the warehouse as a first‑class destination, providing near‑real‑time sync and extensive transformation capabilities while keeping data under your control.
The platform offers over 90 native integrations, Segment‑compatible SDKs, and a JavaScript engine for custom event enrichment. Built in Go with a React UI, it runs on a single PostgreSQL instance and can be deployed via Docker, Kubernetes, or Helm charts for production‑grade high availability (99.99% uptime). Privacy‑first features let you filter or mask sensitive fields before forwarding data.
Start with the free RudderStack Cloud tier or self‑host using the provided Docker images. Verify your setup by sending test events, then scale to unlimited event volumes as needed.
When teams consider RudderStack, these hosted platforms usually appear on the same shortlist.
