Show HN: Data Studio – Open-Source Data Notebooks Hey HN, I am Alex. I am open sourcing Data Studio, a lightweight data exploration IDE in your browser that runs locally. Try it: https://ift.tt/Hv1UWzQ (no account needed, runs locally) More information: https://ift.tt/YTrCaX8 I love working with data (Postgres, SQL, DuckDB, DBT, Iceberg, ...). I always wanted a data exploration tool that runs in my browser and just works. Without any infra or privacy concerns (DuckDB UI came quite close). Features: - Data Notebooks - SQL cells work like DBT models (they materialize to views) - Use Python functions inside of SQL queries - Use DB views directly in Python as dataframes - Transform Excel files with SQL - You can open .parquet, .csv, .xlsx, .json files nicely formatted If you like what you see, you can support me with a star on Github. Happy to hear about your feedback <3 https://github.com/dataspren-analytics/data-studio February 17, 2026 at 04:10AM
