GrabGPU vs Cloud-GPUs.com: Stop Comparing GPU Prices You Can’t Rent

You know how it goes. You open a GPU comparison table, sort by price and find a cheap H100. You click through, sign up, add a card, open the console, and the region you need has nothing free.

The price was real. The GPU just wasn’t available.

That’s the gap between a price table and an availability table. This post compares GrabGPU with Cloud-GPUs.com, one of the best-known GPU comparison sites, and explains which one fits which renter.

What Cloud-GPUs.com does well

Cloud-GPUs.com covers a lot of ground. Its homepage lists 30+ providers and 75+ GPU models, with bare metal and virtual machines, and on-demand, spot and reserved pricing. You can filter by region (Europe, the US, Canada and India), and it has a cost calculator and guides such as one on renting versus buying hardware for LLM inference. It also covers NVIDIA and AMD cards, from the RTX 5090 up to the B300/B200 and H200/H100.

If you want to survey the whole market, including reserved contracts and spot bids, it’s a solid place to start.

Its homepage doesn’t say whether the listed capacity is in stock right now, though. You get a price, and you find out about availability after you click through.

What GrabGPU does differently

GrabGPU is built around one question: can I rent this card right now?

Each price on GrabGPU comes with the stock status the provider reported when the data was collected. The /in-stock/ page goes further: it lists only capacity that a provider confirmed is available, cheapest first.

Here’s what the live site showed when this post was written:

• 71 GPU models across 22 providers and 869 configurations
• 45 models with confirmed stock. The rest have a price but no confirmed capacity, and GrabGPU tells you so.
• H100: 16 providers list it and 7 have it in stock, from $1.11 per GPU-hour
• The typical GPU model is 13% cheaper at its cheapest provider than at the median one

Think about that H100 line. If you had picked a provider from a price list alone, odds were better than even that you’d have landed on one without confirmed stock.

Head to head

• Main question it answers. Cloud-GPUs.com: what does a GPU cost across 30+ providers? GrabGPU: what does it cost, and can I rent it today?
• Stock status. Cloud-GPUs.com: not advertised on its homepage. GrabGPU: shown next to every price, with a dedicated in-stock page.
• Coverage. Cloud-GPUs.com: 75+ models, 30+ providers. GrabGPU: 71 models, 22 providers, 869 configurations.
• Pricing types. Cloud-GPUs.com: on-demand, spot and reserved. GrabGPU: headline prices are on-demand only. A preemptible spot bid isn’t the same product as an hour you can keep, so it never sets the headline price.
• Where the data comes from. GrabGPU pulls from four public provider APIs (Shadeform, Vast.ai, RunPod and Lium) and never copies another comparison site.
• Market view. GrabGPU’s price index shows the floor, median, ceiling, spread and $/TFLOP-hour for each model.
• Switching providers. GrabGPU has alternatives pages that, for each of a provider’s GPUs, show which clouds undercut it and the cheapest in-stock swap.
• Data residency. GrabGPU lists GPU clouds by country, for when your data has to stay in one jurisdiction.
• Developer access. GrabGPU offers free JSON endpoints with no sign-up and no key, and every offer includes a rent_url. It also ships an MCP server with a find_gpu tool, built for AI assistants like ChatGPT and Claude.

The cost of picking on price alone

A price that comes with no stock status costs you time. That means another signup, another console and another “no capacity in this region” message, often right when your training run or demo is due.

GrabGPU flips the order. You start with what’s available and pick the cheapest from that. You see the median too, so you know how much you’d overpay with the wrong provider. For a typical model that gap is 13%, and on a multi-GPU, month-long job it adds up quickly.

Which one should you use?

Choose Cloud-GPUs.com if you’re planning ahead: comparing reserved contracts, pricing spot capacity, or scanning the widest list of providers and models.

Choose GrabGPU if you need a GPU today. That covers an ML engineer with a job queued, a founder who needs an H100 before the demo, or anyone who has already had a price quoted and wants to know if they can actually get the card.

Many renters will use both: one to map the market, the other to find capacity they can actually rent.

Check stock before you rent

GPU stock changes all the time, and the cheap in-stock offer you see now may be gone by the next update. Don’t learn that from a provider’s console.
