  Felis Cloud is priced purely on usage time against the target class, with a monthly free
  allowance on each. There are no named tiers, no seat pricing and no published API-call
  pricing — the meter is wall-clock time on the backend. Subscription and billing run through
  Google Cloud Marketplace. Alice & Bob states that pricing can be customised for large
  volumes or for access outside the public availability hours.
