Running into quotas

FCM is free and unlimited for all Firebase plans (pricing page).

We don't impose a limit on the number of messages you can send, but there is a limit on how many messages you may send per second. Although there's no specific number, sending too many messages in a small time frame can set off our abuse detection systems and result in either a DeviceMessageRateExceeded or TopicsMessageRateExceeded error.
