🔍 Viewing Data

PyStack't creates DuckDB database files. From DuckDB version 1.2.1 onwards, you can explore them using the UI extension. Below code will load the UI by navigating to http://localhost:4213 in your default browser.

import duckdb

with duckdb.connect("./stackt.duckdb") as quack:
    quack.sql("CALL start_ui()")
    input("Press Enter to close the connection...")

Alternatively, you can use a database manager. You can follow this DuckDB guide to download and install DBeaver for easy access.
