Bedevere

A tabular data visualizer and DuckDB SQL editor for the browser. Use it as a standalone web app, or embed it in your own page via the npm package.

What it does

• Open CSV, Parquet, JSON, and Arrow files directly in the browser — no upload, no server round-trip.
• Write DuckDB SQL against them with a real editor: syntax highlighting, completion, and instant results.
• Pivot, filter, and chart the result table without leaving the page — or plot straight from SQL with the VISUALIZE directive, a DuckDB SQL extension.
• Embed the same surface in your own product: @kolistat/bedevere-wise on npm.

Where it fits

Bedevere is for any analyst who needs to look at a table, run a query, and ship the answer — fast. It runs on the same in-browser DuckDB engine that powers the rest of KoliStat, tuned for interactive exploration: open a file, write SQL, visualize, done.
