oleander is a serverless, multi-engine data warehouse for agents and builders. Most queries don't need a cluster. Run SQL with DuckDB, DataFrames with Polars and distributed workloads with Spark or Bloom (Apache DataFusion). Intelligent routing picks the right engine and capacity to optimize cost and performance. Query your own open data or use oleander-managed Iceberg. Give agents secure and scoped MCP access and trace execution with OpenLineage.
