Rates

Sticker prices below; the meter charges elapsed seconds. CPU and RAM only while the machine is running. Disk (and snapshots) while they exist — including stopped.

ResourcePriceWhen
vCPU€0.035 / vCPU-hourSeconds while running
RAM€0.012 / GiB-hourSeconds while running
Storage€0.050 / GB-monthSeconds the disk exists
Snapshots€0.050 / GB-monthSeconds the snapshot exists

A 1 vCPU + 1 GiB sandbox is €0.047/hour of compute while running (billed per second), plus disk at the storage rate. €5 ≈ 105 such machine-hours of compute; €30 ≈ 635.

FAQ

How does the trial work?

€5 free on signup (no card). Add a payment method — setup only, not a charge — for +€25 once (€30 total). Usage spends the balance at the rates above.

What happens at €0?

New machines block; running ones pause. Data kept for a grace window (3 days free / 30 days after a top-up). We email before delete. Top up any time to resume.

Is there a subscription?

No. Prepaid only — no platform fee. Your balance is the spend cap.

Hour or second?

Billed per second, same as Modal and E2B. The numbers on the table are the sticker (per hour for CPU/RAM, per GB-month for disk) so they compare. A 5-second sandbox is 5 seconds of those rates, not a rounded hour. Stopped machines pay disk only.

When does the cloud open?

Soon — we're inviting people in batches from the waitlist. Request an invite and we'll email you; there's no queue position to game.
