Reflex Cloud is billed on a per second basis so you only pay for when your app is being used by your end users. When your app is idle, you are not charged.

This allows you to deploy your app on larger sizes and multiple regions without worrying about paying for idle compute. We bill on a per second basis so you only pay for the compute you use.

By default your app stays alive for 5 minutes after the no users are connected. After this time your app will be considered idle and you will not be charged. Start up times usually take less than 1 second for you apps to come back online.

• Apps below c2m2 are considered warm starts and are usually less than 1 second.
• If your app is larger than c2m2 it will be a cold start which takes around 15 seconds. If you want to avoid this you can reserve a machine.

If you expect your apps to be continuously receiving users, you may want to reserve a machine instead of having us manage your compute.

This will be a flat monthly rate for the machine.

To monitor your projects usage, you can go to the billing tab in the Reflex Cloud UI on the project page.

Here you can see the current billing and usage for your project.

One thing that is important to note is that in the hypothetical example where you have 50 people using your app continuously for 24 hours or if you have 1 person using your app continuously for 24 hours, you will be charged the same amount as the charge is based on the amount of time your app up and not the number of users using your app. In both these examples your app is up for 24 hours and therefore you will be charged for 24 hours of compute.
