What is MotherDuck?

MotherDuck is a cloud data platform built on top of DuckDB, offering a managed, serverless environment for running DuckDB workloads in the cloud, with features like hybrid execution that can seamlessly split a query between a user's local DuckDB instance and MotherDuck's cloud backend depending on where the relevant data lives.

Rather than requiring a hard choice between "run entirely locally" and "run entirely in the cloud," this hybrid model lets a query touch both local files and cloud-hosted tables within the same statement, with MotherDuck handling the coordination behind the scenes. MotherDuck has also added features like a Postgres wire protocol-compatible connection endpoint (letting BI tools that speak the Postgres protocol connect directly) and, more recently, "Flights," agent-native data pipeline tooling for letting an AI agent build and operate ingestion pipelines.

MotherDuck is a distinct company from DuckDB Labs (the company founded by DuckDB's original creators to support core open-source development), though the two ecosystems are closely connected, and DuckDB itself remains fully usable, free, and open-source with or without ever touching MotherDuck.
