Load any SQLite database, browse its tables, filter rows with a visual query builder, run custom SQL, and visualize your data — all from your browser, with no installation beyond Python.

Instant Database Access

Load any SQLite .db file and immediately browse its tables and schema. Navigate between tables with no imports or extra configuration.

Visual Filter Builder

Build precise queries with 11 filter operators — equals, contains, greater/less than, is null, IN lists, and more — entirely through a point-and-click interface.

Custom SQL Queries

Instant Visualizations

Generate histograms, bar charts, and scatter plots from your data with a few clicks — no coding or data wrangling required.

Counts & Summary Stats

Explore categorical distributions with interactive treemap and sunburst charts. View per-column missingness, unique value counts, and min/max ranges.
