Summary

DuckDB UI is a browser-based interface for working with a local DuckDB instance, added through the ui extension. It includes a SQL notebook with autocomplete and keyboard shortcuts, a catalog browser, a table explorer with column-level statistics, and a results viewer with sorting and filtering. Start it with `duckdb -ui` or `CALL start_ui()`; the interface opens in the default browser and is served by an HTTP server embedded in DuckDB, normally at `http://localhost:4213`. By default, queries run locally and the data and queries stay on the computer. The native DuckDB process gives the interface access to local cores, memory, and files. Connecting to MotherDuck requires opting in and signing in. The UI is free. Direct use with a read-only database is not supported, and the UI does not currently support windows_arm64. The local server fetches interface files from ui.duckdb.org, so configured alternate URLs should be trusted because the application can access loaded DuckDB data.

Who it is for

DuckDB UI suits people who want a browser-based way to explore local DuckDB data and run SQL queries. It may also suit users who want to opt in to a MotherDuck connection.
