Show HN: Queryline – One app for SQL and Firestore with a command palette

2 points

I got tired of switching between one tool for PostgreSQL, another for MySQL, and the Firebase console for Firestore. So I built Queryline — a single, keyboard-driven database client that handles both SQL and NoSQL in one interface.

The features I'm most proud of:

CMD+K everywhere - Jump between connections, tables, recent queries, or export formats without touching the mouse. It's the workflow I always wanted: hit a shortcut, type, done.

SQL + Firestore, unified - Query your PostgreSQL database and browse Firestore collections in the same app. Same keyboard shortcuts, same export formats (CSV/JSON/SQL), same mental model.

Virtual scrolling - 100k+ rows rendered at 60fps. No pagination hell.

Tauri, not Electron - Native feel, OS keychain for credentials, tiny footprint.

Tech: Tauri 2, Rust, Vue 3, Monaco Editor, DuckDB for local caching

Supports: PostgreSQL, MySQL, SQLite, Firestore
