Is there a row limit on the results of a query?

The row limit for all query results is set to 10,000 rows by default. You may specify a row limit up to 50,000 in query parameters for an individual query. If more rows are needed, we recommend using pagination in your application to request more rows.

Can I try Cube Cloud for free?

Yes. Cube Cloud provides free development instances and a set of paid tiers (opens in a new tab). Each tier comes with additional features, however, you're welcome to use development instances indefinitely if they satisfy your needs.
