AWS Agrees to Acquire DuckLabs, Developer of Open-Source Database DuckDB
AWS has agreed to acquire DuckLabs, the developer of the open-source analytics database DuckDB, aiming to scale its capabilities while keeping the project open-source. The deal is expected to close next month.
DuckDB is designed as an embeddable, high-performance analytical database that enables developers to execute complex SQL queries directly from inside their applications or client environments without managing server infrastructure. Often described as the analytics equivalent of SQLite, DuckDB has seen adoption grow to more than three million downloads per day at one point, DuckLabs said.
AWS said it remains committed to maintaining DuckDB as an open-source project, and the independent, nonprofit DuckDB Foundation will continue as the project’s overall steward. DuckLabs’ core engineering team will remain based in Amsterdam, led by co-founders Hannes Mühleisen and Mark Raasveldt.
In a blog post, Mühleisen and Raasveldt said the acquisition deepens a collaboration that began in early 2025, when the two companies worked together to add support for DuckDB in Amazon S3 Tables and Amazon SageMaker Lakehouse. That work was aimed at helping enterprises turbocharge their data operations with embeddable analytics, and they said they will build on it now that they are part of AWS.
AWS Vice President and Distinguished Engineer Andy Warfield highlighted the strong affinity between DuckDB and its developer community. “DuckDB is an incredible open-source project with an amazing community; it is broadly used and very much loved by S3 customers today,” he said. “A lot of what has made DuckDB so successful is the fact that it is completely open-source and easily embeddable in so many types of applications. We are committed to the project’s continued development in open source and under the stewardship of the DuckDB Foundation.”
The transition to AWS will allow DuckLabs to change its business model. Until now, it relied on monetizing open-source users through commercial support contracts and feature development partnerships. Going forward, AWS will provide the funds needed to expand investments in the broader open-source ecosystem. AWS will also establish a technical advisory board within the DuckDB Foundation to gather community feedback on its project roadmap, and will open up DuckDB’s extension ecosystem to support signed extensions from third-party developers.
“We have seen what the DuckLabs and AWS teams can accomplish together,” Mühleisen said. “AWS brings the scale and reach to introduce this technology to many more users, including people who may eventually rely on the Duck Stack without needing to operate a database themselves.”
