Show HN: DuckDB + React = SQLRooms Framework for Analytics Apps Without Backend

We’ve built SQLRooms, an open-source framework for creating single-node data analytics apps powered by DuckDB.

It lets you build fully client-side, data-centric apps using React and DuckDB running in the browser (via WebAssembly) or in Electron. No server or backend is required — apps can work offline, preserve data privacy, and run queries on large datasets with sub-second performance.

Features:

- Query large datasets in browser with DuckDB (WASM)

- Modular design for building composable data UIs (query editors, dashboards, notebooks, etc.)

- Data privacy-preserving AI assistant that can write and execute SQL queries

- Integrations with various visualization libraries
