WhichVM

Remember the last time you needed to find the cheapest cloud VM for a workload? You opened five tabs — the AWS pricing page, the Azure calculator, GCP Compute Engine, a Reddit thread from 2023, and probably vantage. Thirty minutes later you still didn’t know whether c7g.xlarge was actually cheaper than c6g.xlarge.

I wanted to find the right instance for a workload quickly — without digging through provider dashboards, pricing PDFs, or half-accurate Reddit threads. So I built WhichVM to save that time for anyone else doing the same thing. Every cloud VM, every region, one table — filter, sort, compare.

Today that’s 3,029+ instances across 138 regions. On-demand, reserved, spot, committed-use — pick your commitment model and the table updates. No logins. No signups. No paywall.

Start with the full AWS table at us-east-1, jump to side-by-side compare, or pick an instance directly:

Or compare two side by side — some common matchups:

• t3.micro vs t2.micro — the free-tier holdouts
• c5.xlarge vs m5.xlarge — compute vs general purpose
• t3.medium vs t4g.medium — x86 vs ARM Graviton
• g4dn.xlarge vs p3.2xlarge — GPU inference vs training
• c5.2xlarge vs c6i.2xlarge — generational upgrade

Data refreshed daily from official AWS, Azure, and Google Cloud APIs. Pricing shown in USD; the app supports every currency the providers publish. Price-history view and per-region anomaly alerts are on the roadmap.
