What counts as compute time?
Compute is the sandbox memory limit multiplied by running time. It is not based on observed memory use or host oversubscription. Paused sandboxes stop accruing compute charges.

Pay for compute. Keep persistent state.
Two usage rates in USD. Running sandbox memory is compute; volumes, snapshots, and retained rootfs data share one storage rate.
Paused sandboxes stop compute charges. Retained state continues to accrue storage by byte-time.

Every meter, in one place.
Compute follows the configured memory limit, not observed usage. Durable data is measured as byte-time, whether it lives in a volume, snapshot, or persistent rootfs.

02Worked example
Four GiB. Ten hours. One clear total.
Add 20 GiB of persistent storage retained for a full billing month. Network traffic and object-store requests add no charge at the current rates.

How is a storage month calculated?
Storage is prorated by the hour using a 730-hour billing month. One GiB retained for a full billing month costs $0.02.
03
Are network traffic and storage operations charged?
No. Ingress is free, egress is temporarily free, and object-store GET and PUT requests have no per-request charge.
