About RudderStack
Open lakehouse streaming and modern native SDKs reshape what RudderStack delivers.
RudderStack is shipping at high cadence across three vectors: open data infrastructure (Snowflake Iceberg streaming destination, P95 latency alerts at GA), modern native SDKs (new Kotlin Android SDK and Swift iOS SDK replacing legacy versions), and integration breadth (Custom Web Device Mode, Singular v2/SDID auto-routing, Braze multi-app keys). Bot Management, Tracking Assistant, and Snowflake Streaming GA from prior weeks set the stage.
