Metered rates
Billed per second, rounded up, and identical at every level. You never pay more per unit as you scale.
- vCPU
- $0.0504/ vCPU-hour
- Memory
- $0.0162/ GiB-hour
- Storage
- $0.000208/ GiB-hour
Running sandboxes bill vCPU, RAM, and storage. Paused sandboxes bill storage only. Killed sandboxes bill nothing.
Set a hard spend cap. Corevelos stops before you cross it, so a runaway agent can never run up a surprise bill.
Limits that grow with you.
No plans to choose and nothing to upgrade. Every feature is included from your first free sandbox. As your total top-ups pass each amount below, your account limits rise automatically and for good. Nothing resets, and nothing downgrades.

Pricing questions, answered.
Do I need a credit card to start?
No. You get $200 in free usage credits the moment you sign up, with no card required. Add a payment method only when you want to top up.
What exactly am I billed for?
The vCPU, RAM, and storage a sandbox holds, metered per second it runs. Running sandboxes bill all three, paused sandboxes bill storage only, and killed sandboxes bill nothing.
Do my credits expire?
No. Credits do not expire or reset monthly, and nothing auto-recharges. Every top-up is a one-time choice you stay in control of.
How do my limits increase?
Automatically. As your total top-ups pass each milestone, your resource ceilings and rate limits rise immediately and never fall. There are no plans to pick and nothing to upgrade.
Can I cap my spending?
Yes. Set a hard spend cap and Corevelos stops before you cross it, so a runaway agent can never run up a surprise bill.
Is there any commitment or lock-in?
None. There is no subscription and no seats. You pay only for what you run, and you can stop anytime by pausing or deleting your sandboxes.
