Starlake documentation
Two open-source products, one platform
Both Apache-2.0 with a standing commitment never to relicense, both free of telemetry, both running entirely on your own infrastructure.
Declarative data pipelines
Starflow
Extract, load, transform, and orchestrate with one YAML file per table. You declare what, Starflow generates the how for DuckDB, BigQuery, Snowflake, Redshift, PostgreSQL, or Spark, with DAGs for Airflow, Dagster, and Snowflake Tasks.
Autoscaling DuckDB fleets
Quack on Demand
A multi-tenant Arrow Flight SQL gateway for DuckDB and DuckLake: one governed, horizontally-scaled endpoint with per-tenant isolation, fine-grained ACLs, federated queries, and ODBC/JDBC/ADBC access.
