Run SQL online with an editable SQLite sandbox

This is a free online SQL editor with a real SQLite backend. Write SQL queries directly in your browser, edit the seed tables in the grid, press Run, and get your result set rendered as a table in seconds — no database install, no connection string, no setup.

Under the hood, 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. Whether you're prepping for a SQL interview, debugging a query, or exploring joins, this SQL playground gets you from question to result in seconds.

What makes this SQL playground useful

  • Instant query execution — write SQL, press Run, and see the result set render 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 — run real queries 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 completely free — no sign-up, no database to install, 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 our sandbox — you just 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 our servers — 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 structured SQL practice, Coddy's interactive SQL course walks you from SELECT basics to window functions with exercises.
