Spending limits

To help manage costs, the App Engine standard environment supports per-project spending limits. If daily costs exceed the spending limit, all operations that exceed free tier quotas will fail. This can be useful to ensure that unexpected usage spikes do not rack up extremely large bills.

Spending limits apply only to App Engine resources, and are only applicable in the App Engine standard environment—services running in the flexible environment will not be affected. Be aware that any services operating beyond the free quota of instance hours will be disabled once the spending limit is reached.

To create a spending limit, go to Navigation menu | App Engine | Settings and click EDIT. Provide a spending limit in the Daily spending field and click Save.
