Prerequisites:

• Bun
• Rust

Desktop app:

bun install
bun run tauri dev

Web app:

cd web
bun install
bun run dev

• bun run dev - Start desktop Vite dev server
• bun run tauri dev - Start Tauri desktop app
• bun run tauri build - Build desktop app
• bun run lint - Run oxlint
• bun run fmt - Format with oxfmt

QueryStudio persists app configuration in a single settings.json file in the Tauri AppConfig directory. Chat sessions are stored locally in chats/<chat-id>.json with metadata in chats/index.json in the same directory.

• macOS: ~/Library/Application Support/<bundle-id>/settings.json
• Windows: %AppData%\\<bundle-id>\\settings.json
• Linux: ~/.config/<bundle-id>/settings.json

The file is created automatically on startup if missing. If the file is invalid JSON, QueryStudio backs it up and regenerates defaults.
