Run SQL online with an editable SQLite sandbox

A free online SQL editor with a real SQLite backend. Write SQL queries in your browser, edit the seed tables in the grid, press Run, and the result set renders as a table in seconds. No database install, no connection string, no setup.

Queries run against SQLite in a sandboxed container, so you get real SQL semantics — JOINs, GROUP BY, window functions, CTEs — without installing anything. The editor has SQL syntax highlighting and keyword autocompletion; the results grid renders query output as a browsable table. Good for prepping for a SQL interview, debugging a query, or exploring joins.

What makes this SQL playground useful

Instant query execution — write SQL, press Run, and the result set renders as a table in seconds.
SQL syntax highlighting, keyword autocompletion, and a results grid that renders your query output as an editable table.
Zero install: no SQLite, no MySQL client, no connection string. Write SQL online from any browser.
Real SQLite backend with editable seed tables — add rows or columns in the grid, then query them with SELECT, JOIN, GROUP BY, or window functions.

What you can try in the SQL playground

SELECT, WHERE, JOIN, and GROUP BY against the sample employees and departments tables.
Edit seed tables in the grid: add columns, change rows, or replace them entirely with your own CSV data, then query them.
Window functions (ROW_NUMBER, RANK, SUM OVER), CTEs (WITH clauses), and aggregate queries against SQLite.

Online SQL editor FAQ

Is the online SQL editor free?

Yes, the SQL playground is free to use. No sign-up, no database to install, and no connection strings — just write a query and press Run.

Do I need SQLite or a database installed?

No database or client to install. Queries run against a real SQLite instance in the sandbox. You write the SQL and press Run.

Does the SQL editor work on mobile?

Yes. The SQL editor runs on desktop, tablet, and mobile browsers. The table grid and query editor both adapt so you can write queries anywhere.

Is it safe to run SQL queries here?

Yes. Each SQL query runs against a fresh SQLite sandbox on the server. There's no persistent database and nothing from your browser or device is exposed.

How do I learn SQL after trying the playground?

Start by running the sample query, then change the WHERE clause or add a JOIN. When you want something more structured, Coddy's interactive SQL course walks you from SELECT basics to window functions with exercises.
