Machine sizes and prices
The small, default, large, and xlarge sizes, their resources and hourly prices, how to read them from the plan catalog, and which sizes a trial can use.
Every machine runs on a plan from the catalog: its vCPUs, memory, disk, and hourly price. VMYard offers four sizes on each kind of host.
| Size | vCPU | Memory | Disk | Price per hour | Multiplier |
|---|---|---|---|---|---|
small | 2 | 4 GiB | 12 GiB | $0.015 | 0.5 |
default | 4 | 8 GiB | 50 GiB | $0.030 | 1 |
large | 8 | 16 GiB | 125 GiB | $0.060 | 2 |
xlarge | 16 | 32 GiB | 250 GiB | $0.170 | about 5.67 |
Machines are billed per second while they run at their size's hourly price; stopped machines cost nothing. The multiplier is the price relative to default, and is what usage and invoice lines report.
Read sizes from the catalog
GET /v1/plans lists every plan with its size (small, default, large, xlarge, or null for plans a deployment added itself), backend, resources, and price (hourly and monthly as decimal strings, monthly being 730 hours).
curl "$VMYARD_API_URL/v1/plans" -H "Authorization: Bearer $VMYARD_API_KEY"{
"id": "0c47a106-0000-4000-8000-000000000012",
"version": 1,
"name": "default",
"size": "default",
"backend": "kvm",
"cpu": 4,
"memory_mib": 8192,
"disk_gib": 50,
"price": { "currency": "USD", "hourly": "0.030000", "monthly": "21.900000", "effective_from": "2026-01-01T00:00:00Z" }
}Each size exists once per host kind (kvm and docker). A machine's plan must match its region's backend, so pick the plan of the right size whose backend equals the region's. The console's create page does this for you: its Size picker lists the chosen region's sizes with their resources and hourly price, and keeps your size when you switch to a region that offers it.
Sizes during the trial
While an organization is on its trial, only small and default can be created or started; anything priced above default answers 403 trial_machine_class_not_allowed. The console shows large and xlarge as locked and says why. Buying credits or a plan lifts the restriction once the first payment is confirmed.
