Frequently Asked Questions

Is this a real database?

No, this is a JavaScript simulation running in your browser memory. It supports standard SQL syntax but is not persistent.

Can I save my data?

Since it runs in memory, data is lost on refresh. However, you can export query results to CSV or JSON using the buttons in the results toolbar.

Is my data private?

Yes. The engine runs 100% client-side. No data is ever sent to a server. You can use this safely without an internet connection once the page is loaded.

Which SQL dialect is this?

It is a custom implementation loosely based on standard ANSI SQL. It supports basic operations like SELECT, INSERT, UPDATE, DELETE, and common aggregates.
