Azure VM pricing & specs dataset

Every Azure virtual machine size with its specs and USD list prices in 24 regions: Linux and Windows pay as you go, 1- and 3-year reservations, and 1- and 3-year savings plans. Refreshed every Monday and published as plain JSON and CSV.

This is the data behind cld2day.com/tools/azure-vm, the Azure VM size finder and the Azure VM cost calculator.

Files

File	What it is
`data/azure-vm-prices.csv`	One row per size and region. Sorted, so the git history of this file is the price history.
`data/azure-vm-sku-catalog.json`	Same data, nested by size (compact keys, see below).
`data/azure-vm-price-changes.json`	Weekly change reports: new sizes, retired sizes, region changes, price moves.
`data/meta.json`	Snapshot date and counts.
`mcp/`	An MCP server so AI assistants (Claude, Copilot, Cursor) can query this data.

CSV columns

size, region, region_name, category, series, vcpus, memory_gib, gpus, arch, temp_disk_gib, linux_payg_hourly, windows_payg_hourly, reserved_1y_hourly, reserved_3y_hourly, savings_plan_1y_hourly, savings_plan_3y_hourly

All prices are USD per hour per VM. An empty cell means Azure does not sell that option for the size in that region.

How it is built

Specs: az vm list-skus --all --resource-type virtualMachines in each region (vCPU, memory, GPUs, temporary disk, data disks, NICs, accelerated networking, Premium SSD, CPU architecture).
Prices: the public Azure Retail Prices API, USD retail prices.
- Spot and Low Priority meters are excluded.
- Reservation prices are published as a term total, so they are converted to an effective hourly rate (÷ 8,760 or ÷ 26,280).
- Reservations and savings plans cover compute only, so Windows license costs are not included in r1/r3/s1/s3.
Only sizes with a Linux pay-as-you-go price in at least one region are included.

These are list prices before taxes and any negotiated discount (EA, MCA, CSP). Not affiliated with or endorsed by Microsoft.

Use it from an AI assistant (MCP)

json

{
  "mcpServers": {
    "azure-vm-pricing": { "command": "npx", "args": ["-y", "azure-vm-pricing-mcp"] }
  }
}

Then ask things like "cheapest 8 vCPU / 32 GB VM in West Europe" or "compare D4s_v5 and D4as_v6 on a 3-year reservation". See mcp/README.md.
