We build with DuckDB. Extensions. Products. Consulting. Tools.

🚜 Query.Farm

We build with DuckDB — extensions, products, consulting, and tools.

🦆 DuckDB, Extended

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.

💼 What We Offer

🧩 DuckDB Extension Development

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.

🛠️ Tools & Products

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.

🧠 Expert Consulting

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.

👋 Let’s Talk

If you’re building with DuckDB — or want to — we’d love to help.
