A full SQLite engine runs right in your browser via WebAssembly. Write any SQL — SELECTs, JOINs, aggregations, CTEs — and get results in milliseconds. No server, no signup.
SELECT department, AVG(salary) FROM sample_employees GROUP BY department;
Import Any CSV
Upload CSV files and they become SQL tables automatically. Column types are inferred (INTEGER, REAL, TEXT) and table names are sanitized. Import as many files as you need.
customers.csv → SELECT * FROM customers;
JOIN Across Files
Import multiple CSVs and query across them like a real database. JOINs, subqueries, UNION — everything works because it's real SQLite under the hood.
SELECT c.name, o.total FROM customers c JOIN orders o ON c.id = o.customer_id;
