SQLite Playground
This free SQLite playground tool lets you write and run SQL against a real SQLite database that lives entirely in your browser. Create tables, query data, or open an existing .sqlite file — nothing is ever uploaded.
How to use SQLite Playground
- 1 Write SQL in the editor and click Run or press ⌘⏎ / Ctrl+Enter to execute it (or just the selected text).
- 2 Load sample to explore a ready-made database, or Open .sqlite to bring in your own file.
- 3 Browse tables from the schema panel and read results in the grid; click any cell to copy it.
- 4 Export a result as CSV or JSON, or Export .sqlite to save the whole database to your device.
Frequently asked questions
Is my database uploaded to a server?
No. The SQLite engine runs in your browser and the database stays on your device — nothing is sent anywhere, so it's safe for private data.
Is my data saved when I close the tab?
When your browser supports OPFS the database persists locally between visits, and your last query is remembered too. If persistence isn't available you'll see a warning — export the database to keep it.
Can I open an existing SQLite file?
Yes. Click Open .sqlite to load a .sqlite, .db or .sqlite3 file, then query it right away. You can also export the current database back out at any time.
Does the playground work offline?
Yes. PDFPowerHub is a PWA, so once loaded it keeps running SQL with no internet connection.
