All figures are the providers' own published list prices in USD, on-demand monthly. The index was last refreshed 2026-10-14, and every row shows the date its own price was read. Nothing here is live or negotiated pricing. Where a provider bills a public IPv4 address on top, it is added to the monthly price, the ranking and every cost per vCPU or per GB, and the row shows the parts: the server, any disk priced apart, and the IPv4 charge. Some prices exclude VAT or need a commitment; the plan notes say which. Check the provider's pricing page before you commit.
