AWS has acquired DuckLabs, the company behind the open-source in-process analytics database DuckDB, in a move the cloud giant says reflects its broader thinking on the future of application building and data analytics. Although AWS already runs its own data warehouse in Redshift and does not gain DuckDB's intellectual property, since the database remains open source, executives argue the deal is less about owning the technology and more about positioning DuckDB as a lightweight "connective tissue" layer that links diverse data tools, engines and platforms, including rivals such as Google BigQuery and Microsoft Fabric.

DuckDB runs embedded within a host application rather than requiring separate server software, letting developers process smaller datasets locally before "graduating" larger or centralised queries to external engines like Redshift or RDS via SQL commands. DuckLabs was founded by DuckDB creators Hannes Mühleisen and Mark Raasveldt, both researchers at Amsterdam's Centrum Wiskunde & Informatica; the software stays under the MIT licence and the independent, non-profit DuckDB Foundation will continue setting strategic direction, though its governance is expected to broaden. Andy Pavlo of ClickHouse Labs welcomed the deal, suggesting AWS funding would help cover rising development costs, including AI-agent-driven CI/CD infrastructure, without altering the project's long-term direction; AWS is not alone in backing DuckDB, with Jordan Tigani's MotherDuck also building a commercial cloud service around it.
