## Usage limit

The Apify platform also introduces usage limits based on the billing plan to protect users from accidental overspending. To learn more about usage limits, head over to the [Limits](https://pr-2390.preview.docs.apify.com/platform/console/billing.md#limits) section of the docs.

View these limits and adjust your maximum usage limit in [Apify Console](https://console.apify.com/billing#/limits):
