How to use SQL Playground
Pick a sample database, write queries and see every statement’s results — SQLite runs on your device.
- Write code or load an example.
- Press Run (Ctrl+Enter).
- Read the output and fix errors.
- Share a link, download the file or keep the draft in this browser.
Questions
Which database engine is it?
SQLite 3 compiled to WebAssembly (sql.js). Every run starts from the chosen sample database, so results are repeatable.
Can I open my own database file?
Use the SQLite Viewer to browse an existing .sqlite or .db file read-only.
Is my code uploaded?
No. It runs in your browser and drafts are saved only in this browser. Share links keep the code in the part of the URL after #, which browsers never send to a server.
