Run SQL directly in your browser with Toolaska SQL Playground, a free online workspace powered by DuckDB-WASM. It loads sample relational datasets for employees, departments, projects, and orders, so you can explore queries, filters, aggregations, joins, and window functions without installing a database.
Use 12 guided query presets to get started, or write your own SQL. Review query results, inspect visual execution plans and the schema ER diagram, create custom tables, and import CSV or JSON data. The workspace also includes query history and bookmarks, SQL snippets, a formatter, and a cheat sheet.
Queries and sample data are processed client-side in your browser; the playground does not send them to a server. It is designed for learning, experimentation, and lightweight prototyping, not production database hosting.
