On: How not to get a $30k bill from Firebase

Don't forget they are only warnings, they will not shut down your app and their update rate is not as frequent as you might expect.

App Engine PM: the GAE Daily Spend limits are hard caps that will shut down services when hit. They are different from the broader GCP Billing Alerts which are simply notifications.

The issue is that they only apply to certain GAE services (compute, legacy APIs, etc.) and not across the platform.

Thank you for correction!

If the concern is DB operations adding up you can lower your quota as well which will be strongly enforced and shut down your app.
