DuckDB

Databox

“DuckDB does the heavy lifting for dataset preparation. It lets us process and structure large API responses efficiently, so users get clean, query-ready datasets without the overhead of a heavier database.”

Evidence

“We use DuckDB WebAssembly as the core of Universal SQL and it has made it possible to deliver incredibly fast, interactive apps. The DuckDB team and community are phenomenal.”

Baselight

“Enabled lightweight, high-performance local querying for structured data analysis.”

Fabi.ai

“Provides low latency, high scalability for data caching and analysis.”

“DuckDB powers our analytics engine for SQLite, CSV, Excel files and more. We couldn't have built CamelAI without DuckDB. It's enabled us to execute SQL queries that used to take minutes in seconds.”

“Our built-in SQL cells are powered by duckdb, which makes it possible to execute blazingly fast queries against Python dataframes as well as external databases like SQLite and Postgres.”

“DuckDB is an in-process SQL OLAP database management system. It’s the fastest-improving in-process SQL OLAP database on the planet. At MotherDuck, we are grateful to be part of the broader DuckDB ‘flock’ and to give back to this community by developing thoughtful, accessible projects like the DuckDB UI. To Hannes and Mark, the creators of DuckDB: We are deeply grateful for the strength of our partnership, and we look forward to co-creating the future of analytics with you. Onward!”

“The incredible in-process SQL database that makes DataKit possible. DuckDB's WebAssembly support lets us run a full-featured SQL engine directly in the browser, processing gigabytes of data locally at lightning speed. Absolute game-changer! 🦆”

“Fast SQL queries directly on Parquet catalog.”

“It’s insanely fast for local analytical workloads, and integrates beautifully with Pandas. Perfect for CSVs and Parquet files in browser-based workflows. It also doesn’t need a server or setup which is a huge win for interactive demos. DuckDB + Pyodide works surprisingly well. You can compile DuckDB to WebAssembly and run SQL queries in-browser with zero backend.”

“DuckDB WASM is used as database engine in the browser.”

“DuckDB is at every layer of the Summer platform. Its light weight executable, high performance, and operational ergonomics make it the perfect for moving, querying, and visualizing data.”

“Beautiful option for quick queries on large datasets”
