What is Duck-UI? ​

Duck-UI is a modern web interface for DuckDB, the fast in-process analytical database. It leverages DuckDB's WebAssembly capabilities to run entirely in your browser, providing a powerful SQL editor and data analysis platform without requiring any server infrastructure.

Key Features ​

• 🦆 No Server Required: DuckDB runs in your browser via WebAssembly
• 📁 Import Anything: Load CSV, JSON, Parquet, Arrow files from local storage or URLs
• 💾 Persistent Storage: Save databases using OPFS for data that persists across sessions
• 🔌 External Connections: Connect to remote DuckDB servers when needed
• ⚡ Lightning Fast: Near-native performance thanks to WebAssembly
• 🔒 Privacy First: All data processing happens client-side

Requirements ​

• Modern web browser with WebAssembly support:
  • Chrome/Edge 88+
  • Firefox 79+
  • Safari 14+
• Docker (for containerized deployment) or Bun/Node.js 20+ (for building from source)
• No database server needed for local WASM mode

Use Cases ​

Data Analysis ​

Analyze CSV, JSON, or Parquet files directly in your browser without uploading to a server:

SELECT product, SUM(sales) as total_sales
FROM read_csv('sales_data.csv')
GROUP BY product
ORDER BY total_sales DESC;

Quick Prototyping ​

Test SQL queries and data transformations without setting up infrastructure:

-- Load data from URL
CREATE TABLE products AS
SELECT * FROM read_parquet('https://example.com/products.parquet');

-- Run analytics
SELECT category, AVG(price) as avg_price
FROM products
GROUP BY category;

Learning SQL ​

Perfect environment for learning SQL with instant feedback and no setup:

• Import sample datasets
• Write queries with autocomplete
• See results immediately
• No database configuration needed
