A fast, native notebook for DuckDB
Write SQL and Markdown side by side, attach multiple databases, chart your results, and inspect your columns — all on your machine.
No account. No cloud. Your data stays on your machine. · Windows & Linux coming soon.
Every database, one session
Attach several DuckDB files and query across them (catalog.schema.table). A live tree of databases, schemas and tables — preview, rename, drop and export.
Run SQL, see results fast
A virtualized grid streams rows as they arrive — sort, copy cells, and export to CSV, Parquet or JSON.
Autocomplete that knows your schema
Context-aware completion for tables, columns and DuckDB functions, plus handy snippets — so you type less and ship queries faster.
See your columns, chart your results
Per-column distributions, distinct counts, null % and quick stats in a diagnostics panel — and turn any result into a chart.
Bring your data in
Import CSV, Parquet, JSON and Excel — drag a file onto the window, or paste a table straight from your clipboard.
Plus a command palette, an extensions manager, saved queries, a per-cell target database, keyboard shortcuts, and automatic update checks.
Tables, charts and column diagnostics side by side — one notebook per analysis.
