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 — as an @kolistat/bedevere-wise npm component, or a single /embed iframe with no build step.

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 grammar (ggsql), which now aims to follow the grammar of DuckDB’s ggplot extension.
• Embed the same surface in your own product — the @kolistat/bedevere-wise npm component, or a one-line /embed iframe you prefill with URL parameters (no build step, no backend).

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.

Bedevere Desktop

Prefer a native app? Bedevere Desktop runs real DuckDB on your own machine — full speed, bigger datasets, and files opened in place — in about 75 MB, with no browser sandbox. It’s local-first: your data never leaves your device.

Free during the beta. Windows 10/11 (x64); the installer isn’t code-signed yet, so Windows may warn you — choose More info → Run anyway.
