How Kuraberu works.

A robot reads each provider's own API, public catalog or price page every 3 days. No price is typed in by hand, and none comes from a reseller's copy or a press release. Prices are the standard recurring ones: no promotions, no first-month discounts, no coupons.

Prices in another currency are converted to US dollars at the European Central Bank's rate of the day, and are shown before VAT. Every page says when its prices were read. A price read more than three days ago can still be listed, marked with its date, but it can never be first in a ranking or called the cheapest; neither can a plan the provider shows as sold out. A price that has just changed leads a list only once a second reading on the provider's own page confirms it, or once it has stood for a week.

Every price here is a best estimate: our reading of a public price list on the day shown. A provider can change a price, charge differently by country or add tax at checkout, so check the provider's site for the final price.

Every list is ordered by a number the page names: the monthly price, the price per gigabyte of memory, the hardware you get per dollar, or for AI models the price of a million tokens, blended three in to one out. Nobody can pay to move up, and there is no score we could not show the working for.

A price below what the maker of an AI model charges is ranked only when the seller publishes a reason for it; otherwise it is listed and marked not ranked. A free tier is a limit, not a price, so it is never called the cheapest. Under every ranking, four short lines say where its prices come from, what it leaves out, what decides its order and what may be first. Each section explains its own numbers:

• VPS data health
• How we score an AI model
• GPU cloud data health
• App platforms data health
• Managed databases data health
• Developer APIs data health
• Dedicated servers data health

Nothing from the providers. There are no affiliate links, no sponsored places and no paid listings, so a ranking has nothing to gain from its own order. A link to a provider is a plain link; we count how many people follow it, without knowing who they are, to learn which pages help.

When you describe what you need, a small language model reads your sentence into requirements you can see and change. It never picks the answer: the ranking is done by the same rules as every other list on the site, over today's prices. Kuraberu keeps no copy of what you type, and leaves it out of its analytics.
