Active-CPU billingOnly CPU in use is billed, so idle time costs less; the light-use column shows how much.
$20/mo planThis price only applies on a plan of at least $20 a month.

Vercel Sandbox: plans
Plan	Price	Includes
Hobby	Free[1]	5 Active CPU hours, 420 GB-hours memory, 5,000 creations, 20 GB data transfer a month; 10 concurrent; 45-minute sessions; up to 4 vCPU / 8 GB; creation paused when the quota runs out

Vercel Sandbox: prices per resource
Resource	Price	Per hour
per vCPU	$0.128 /h[1]	$0.128
per GB of memory	$0.0212 /h[1]	$0.0212

Active CPU counts only time the CPU is busy; waiting on I/O, network or model calls is not billed. Provisioned memory is billed for the whole time the sandbox runs, idle or not.
Rates are for the default iad1 region; Active CPU, memory, data transfer and drive rates vary by region. Creations ($0.60 per 1M) and snapshot storage are the same in every region.
Each vCPU comes with 2 GB of memory; 1 or an even number of vCPUs up to the plan maximum.
Sandboxes are persistent by default; stopping one snapshots its filesystem (billed as snapshot storage) and the next call resumes it. Memory and processes are not kept.
Drives (public beta) cost $0.05/GB-month, $0.0015/GB read and $0.004/GB written on Pro.
Shell access is the CLI's `sandbox connect` (aliases `ssh`, `shell`); no SSH endpoint is documented.
