We build with DuckDB — extensions, products, consulting, and tools.
Query.Farm is a product studio focused on extending DuckDB.
We write DuckDB extensions, build developer tools, and help teams embed DuckDB into modern data systems.
If you’re working with DuckDB, we can help you accomplish great things.
We build native DuckDB extensions in C++ and Rust — from custom functions and table sources to new file formats and catalogs.
If DuckDB doesn’t do it yet, we can make it happen.
We’re building software around DuckDB and Apache Arrow: libraries, connectors, developer utilities, and full-stack integrations.
Get in touch to learn more or ask about early access.
From performance tuning to production deployment, we help teams use DuckDB effectively — embedded, at the edge, or in the cloud.
Whether you’re starting fresh or scaling fast, we can guide the way.
If you’re building with DuckDB — or want to — we’d love to help.
We’re data people — database engineers, systems hackers, and DuckDB contributors focused on building powerful, lightweight solutions.
We help teams get the most out of DuckDB: fast, open, and local analytics at your fingertips.
- Query.Farm is an independent company.
- We’re not affiliated with DuckDB Labs or the DuckDB Foundation.
- We build on the public DuckDB project, and deeply respect the team behind it — many of whom we count as friends and collaborators in the broader DuckDB ecosystem.
