In-browser SQLite real-time execution — write SQL, see results instantly
Zero Dependencies · Works OfflineThe SQL Playground is a free online tool that lets you write and execute SQL statements directly in your browser. Powered by SQLite (sql.js WebAssembly version), it supports standard SQL syntax with built-in sample databases. Write SQL and see query results instantly — no database installation or configuration needed. All data is processed locally in your browser with no server uploads.
1. Click "Employees"/"Products"/"Students" to load a sample database, or write CREATE TABLE statements to create your own.
2. Enter SQL statements in the editor. Multi-line editing is supported.
3. Click "Run" or press Ctrl+Enter to execute. Results appear instantly in the table below.
4. Check "Database Schema" to see current table and column information.
5. Click "Export SQL" to save the current database, and "Import SQL" to restore it later.
Need to verify SQL logic during development? No need to start a local database — write and test directly in the browser.
Practice SELECT/JOIN/subquery syntax in database courses with instant result feedback to deepen understanding.
Prepare for technical interviews by practicing classic SQL problems and verifying your solutions.
Import data and use SQL to filter and analyze without installing specialized tools.

SQLite is the world's most widely used embedded database engine, created by D. Richard Hipp in 2000. It features zero configuration, no server, and single-file storage — used by Android, iOS, Chrome, Firefox, and billions of devices. sql.js is SQLite compiled to WebAssembly, enabling it to run in browsers with near-native performance. SQLite supports most of SQL-92 including transactions, triggers, views, and subqueries, but lacks RIGHT/FULL OUTER JOIN and some window functions. For learning and everyday query testing, SQLite is more than sufficient.
SQLite syntax, compatible with most standard SQL (SELECT/INSERT/UPDATE/DELETE/CREATE/JOIN/subqueries/aggregate functions, etc.).
Data is stored in browser memory and resets on refresh. Export SQL scripts to save locally and import them later.
Yes. Use CREATE TABLE to create custom tables, INSERT to add data, and SELECT to query.
No. This tool uses sql.js (SQLite WebAssembly). All SQL execution happens locally in your browser. Your data never leaves your device.
SELECT/INSERT/UPDATE/DELETE/CREATE TABLE/DROP TABLE/JOIN/subqueries/aggregate functions/GROUP BY/ORDER BY/LIMIT/UNION and other SQLite core features.
Yes. Paste SQL scripts or drag and drop .sql files. Built-in sample databases are also available.
