RudderStack

RudderStack is a warehouse-first customer data platform designed to help you take control of your customer data without sacrificing security. Instead of storing your data in a third-party silo, it turns your existing data warehouse into a fully functional CDP. You can collect events from your web, mobile, and server-side applications and route them to over 150 different marketing, sales, and analytics tools in real-time.

You can also use its Reverse ETL capabilities to sync enriched data from your warehouse back into your operational tools. This ensures your entire team works with the same updated customer profiles. Because it is open-source at its core, you get the flexibility to customize your data pipelines while ensuring compliance with strict data residency and privacy regulations like GDPR and CCPA.
