Open Source Data Infrastructure

Build pipelines with Starflow, serve data with Quack on Demand. Each works on its own: Starflow runs on any warehouse, Quack on Demand works with any ETL. Both Apache-2.0.

Starflow
Open-source ELT · Apache-2.0

Declarative data pipelines as YAML.

Ingest, transform, and orchestrate with native SQL on DuckDB, BigQuery, Snowflake, and Redshift. CLI-first. Runs anywhere. Or let Starflow's AI generate the config from plain English.

Quack on Demand
Open-source DuckDB fleet control plane · Apache-2.0

Autoscale DuckDB fleets on demand.

Runs fleets of DuckDB Quack nodes on your own Kubernetes. Per-tenant isolation, fine-grained ACLs, federated queries. Query it from any ODBC/JDBC/ADBC client. Works with any ETL.

Open governance

Safe to depend on. Safe to recommend.

Stays Apache-2.0

Both projects are Apache-2.0 and will stay that way. No relicensing to BSL or SSPL. A public, standing commitment.

No telemetry by default

Neither project phones home. No usage tracking, no contact capture, no visibility into your users.

Open contribution

DCO-signed pull requests, transparent review, issues triaged in public on GitHub.

Public roadmap

Direction is decided in the open. Built on neutral, vendor-agnostic standards (Arrow Flight SQL, DuckLake).
