Turn event-level data into governed, AI‑ready customer insights
Snowplow provides a scalable, glass‑box data pipeline that captures, validates, enriches, and streams event‑level customer data to any warehouse or lake, enabling real‑time analytics and AI applications.

Data can be streamed to any warehouse, lakehouse, or SaaS destination, making it ready for BI, advanced analytics, and AI/ML pipelines.
Snowplow can be self‑hosted on cloud or on‑premise environments and integrates with popular data platforms like Snowflake, BigQuery, Redshift, and Azure Synapse. Comprehensive documentation and an active community support implementation and ongoing operation.

Yes, the pipeline can stream data to popular warehouses and lakehouses such as Snowflake, BigQuery, Redshift, Azure Synapse, and also to custom destinations via HTTP.
