sqlrooms 0.1.0

Local-first SQLRooms project launcher for DuckDB worksheets and Mosaic dashboards.

sqlrooms CLI

Launch a local SQLRooms DuckDB project for adding data, authoring worksheets, and building Mosaic charts and dashboards.

Quick start

# From the repo root
uvx sqlrooms \
  ./sqlrooms.db

What happens:

• Starts the DuckDB websocket backend (from sqlrooms-server) on a free local port.
• Serves the SQLRooms worksheet UI on http://localhost:4173, or the next free port, and opens your browser (disable with --no-open-browser).
• Drag-and-drop CSV, TSV, JSON, Parquet, and DuckDB files to load them into DuckDB; files are uploaded to a local sqlrooms_uploads folder and referenced by path.
• UI state is stored in the SQLRooms meta namespace (default __sqlrooms) of the selected DuckDB file.

CLI flags

• DB_PATH (positional): DuckDB project file to load/create (e.g. sqlrooms ./my.db). Required unless --db-path is provided.
• --db-path: DuckDB database to use as a flag alternative. Pass a filepath to persist, or :memory: for an explicit temporary in-memory session.
• --host / --port: HTTP host/port for the UI. The default bind address is 127.0.0.1. If --port is omitted, 4173 or the next free port is chosen automatically.
• --ws-port: WebSocket port for DuckDB queries. If omitted, a free port is chosen automatically.
• --experimental: Enable experimental artifacts, blocks, commands, and agent tools.
• --experimental-sync: Enable experimental sync (CRDT) over WebSocket (Loro). Requires --experimental.
• --ai-devtools: Enable the AI session devtools button in the UI, including production-built UI bundles. Can also be set with SQLROOMS_AI_DEVTOOLS=1.
• --meta-db: Optional path to a dedicated DuckDB file for SQLRooms meta tables (UI state + CRDT snapshots). If omitted, meta tables are stored in the main DB.
• --meta-namespace (default __sqlrooms): Namespace for SQLRooms meta tables. If --meta-db is provided, used as ATTACH alias; otherwise used as a schema in the main DB.
• --no-open-browser: Skip automatically opening the browser tab.
• --ui: Optional path to a custom UI bundle directory (a Vite dist/). If omitted, uses the bundled default UI.
• --no-ui: Start only the HTTP API server and DuckDB websocket backend; do not serve the bundled/static UI.
• --config: Path to a SQLRooms TOML config file. Defaults to ~/.config/sqlrooms/config.toml (%APPDATA%\sqlrooms\config.toml on Windows).
• --no-config: Disable config file loading.

--host 0.0.0.0 is an advanced local-network mode. Only use it on trusted networks; it exposes the SQLRooms UI/API bind address beyond your loopback interface. The DuckDB websocket backend still enforces local-only connections unless you explicitly use external proxy settings.

There is intentionally no sqlrooms add, sqlrooms import, or sqlrooms doctor command in the first public CLI. Drag-and-drop import is the supported first-launch path, and the release smoke checklist below covers the doctor-style checks for now.

Data persistence

Tables created in the selected DuckDB file (or attached meta DB if --meta-db is provided):

• __sqlrooms.ui_state (one row: key='default')
• __sqlrooms.sync_rooms (only used when --experimental --experimental-sync is enabled)

Uploads go to /api/upload. Runtime config for the UI is exposed at /api/config / /config.json.

Manual smoke test

Use this before release candidates to prove the first-launch path:

uv run --project python --package sqlrooms sqlrooms \
  --no-open-browser \
  ./smoke.duckdb

Then open the printed UI URL and verify:

• The app starts without a database connection error.
• Dragging python/sqlrooms/tests/fixtures/cars.csv into the data panel creates a cars table.
• The uploaded CSV lands next to smoke.duckdb under sqlrooms_uploads/.
• The data sidebar shows main.cars and does not show SQLRooms internal metadata.
• A worksheet is created or selected automatically and contains a cars data-table explorer block.
• Users can create worksheet and dashboard artifacts from the New menu without enabling --experimental.
• Map, notebook, canvas, app, HTML app, pivot, and SQL query surfaces stay hidden unless --experimental is provided.
• Restarting the same command with ./smoke.duckdb restores the imported table and persisted workspace state.

Config file

sqlrooms reads AI provider and connector settings from a TOML config file. AI settings changed in the CLI UI are saved back to this file automatically when config loading is enabled and the config file is writable:

• macOS / Linux: ~/.config/sqlrooms/config.toml
• Windows: %APPDATA%\sqlrooms\config.toml

Override with --config <path>, or disable with --no-config.

Example config file:

[ai]
default_provider = "openai"
default_model = "gpt-5"

[[ai.providers]]
id = "openai"
base_url = "https://api.openai.com/v1"
api_key_env = "OPENAI_API_KEY"
models = ["gpt-5", "gpt-4.1"]

[[ai.providers]]
id = "anthropic"
base_url = "https://api.anthropic.com"
api_key_env = "ANTHROPIC_API_KEY"
models = ["claude-4-sonnet"]

[[ai.custom_models]]
model_name = "local-qwen"
base_url = "http://localhost:11434/v1"
api_key = "local-key"

[ai.model_parameters]
max_steps = 12
additional_instruction = "Prefer short answers."

[[db.connectors]]
id = "postgres-local"
engine = "postgres"
title = "Postgres Local"
host = "localhost"
port = "5432"
database = "postgres"
user = "postgres"
password = "postgres"

[[db.connectors]]
id = "snowflake-prod"
engine = "snowflake"
title = "Snowflake Prod"
account = "your-account"
user = "your-user"
password = "your-password"
warehouse = "your-warehouse"
database = "your-database"
schema = "your-schema"
role = "your-role"
authenticator = "externalbrowser"

[[db.connectors]]
id = "snowflake-dev"
engine = "snowflake"
title = "Snowflake Dev"
account = "your-dev-account"
user = "your-dev-user"
warehouse = "your-dev-warehouse"

Server-only mode (no UI)

If you only want the DuckDB websocket server (no HTTP UI server), install/run sqlrooms-server:

uvx sqlrooms-server --db-path ./sqlrooms.db --port 4000

sqlrooms-server is also available as an alias console script.

Backend connectors (DbSlice bridge)

Use these modes to run remote queries through backend connectors and materialize results into core DuckDB for downstream notebook cells.

Install optional connector dependencies first:

# From python/sqlrooms
uv sync --extra connectors
# or install just one connector:
uv sync --extra postgres
uv sync --extra snowflake

Postgres

uvx sqlrooms \
  ./sqlrooms.db \
  --ws-port 4000 \
  --port 4173

Snowflake

uvx sqlrooms \
  ./sqlrooms.db \
  --ws-port 4000 \
  --port 4173

What this enables:

• sqlrooms exposes connector bridge endpoints under /api/db/*.
• Runtime connector metadata is exposed via /api/config, so frontend DbSlice auto-registers available backend connections.
• Notebook SQL cells can select Postgres/Snowflake connectors from the connector dropdown.
• Arrow payloads are materialized into DuckDB and can be queried downstream in the same session.

Notes:

• Configure connectors in sqlrooms.toml using [[db.connectors]] entries.
• Connector libraries are optional extras (postgres, snowflake, or connectors).

Developer setup

Local dev loop for the CLI and UI:

1. Install deps and build the dedicated UI (from repo root):

pnpm install
pnpm --filter sqlrooms-python build:ui
# build outputs directly to python/sqlrooms/sqlrooms/web/static

2. Dev the Python CLI app from the repo root:

pnpm dev cli

This starts the Python API server on http://127.0.0.1:4273 with --no-ui and the Vite UI on http://localhost:4174. If those ports are busy, the dev script selects the next free API and UI ports from separate ranges and points the Vite proxy at the selected API port. The auto-created dev database is named after the selected UI port, for example sqlrooms-4174.db.

3. Run the Python API server on its own (optional):

cd python/sqlrooms
pnpm dev

Tips:

• Use --no-open-browser if you don’t want the static bundle auto-opened.
• Use --no-ui when pairing the Python API server with the Vite UI dev server.
• Rebuild the UI (pnpm --filter sqlrooms-python build:ui) when you want the Python server to serve new static assets.
• /api/config reflects runtime config (AI providers/default model, DB bridge metadata, WS URL).
