Description

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://local.dataspren.com (no account needed, runs locally)More information: https://github.com/dataspren-analytics/data-studioI 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

Could you build this?

Partial A browser notebook UI is straightforward, but running local SQL and analytics across Postgres/DuckDB entirely inside client-side browser environments requires complex WebAssembly compilation and virtual file systems.

What it would actually take: The stack typically employs React/Svelte for the notebook interface, combined with DuckDB-WASM or PGlite running SQLite/Postgres in browser memory via WebAssembly. Hard parts include managing in-browser multi-threaded WASM workers, indexedDB persistence, streaming query execution, and handling memory-constrained tabular datasets locally. It requires expertise in WebAssembly tooling, browser execution boundaries, and database internals.

Discussion

6 comments analyzed.

Competitors mentioned: remotestorage.com for cloud storage integration, Firefox/Thunderbird tree-listviews (for virtualized list implementation)

Concerns raised: CSV performance extremely slow due to DuckDB limitations in browser (no multithreading/SIMD), Long loading time (tens of seconds) for runtime startup on simple CSV operations, Single active session restriction prevents opening second tab, Data table column misalignment when resizing browser window, Noticeable lag switching between datasets and scrolling virtualized lists

Feature requests: Support drag-and-drop file upload anywhere in window, not just upload button, Manual column resizing with splitter handles, Export to portable self-contained HTML format with 'Open in Data Studio' button, Cross-tab synchronization using postMessage for collaborative editing, Bidirectional sync between local file and Data Studio modifications

Nobody's really built a analytics & bi tool for Legal yet.
