Built for the way engineers actually work.

Dense, precise, and fast. Every surface is tuned for reading data and writing SQL — not marketing gloss.

Claude, built in

Ask in plain English. Claude reads your live schema, writes the SQL, and explains the plan — in the same window.

Schema-aware completion

Completions read your live schema — tables, columns, joins. Tab through a query without guessing names.

Inline editing

Edit cells like a spreadsheet. Stage changes, review the diff, commit as one transaction.

Keyboard-first

Command palette, jump-to-table, run-and-advance. Your hands never leave home row.

Bring your own Claude

Free and open source. No metered agent.
