Why is cloud cost estimation hard?
The hard part is not finding a price page. It is that units, free allowances, and tiers do not add across vendors. This site records public list prices as dated snapshots and computes the same usage against each ladder.

[FAQ] Questions
Are these invoices?
No. They are public on-demand list prices with visible sources. Discounts, taxes, and private networking are out of scope.

Why is history empty?
A history page needs at least three snapshot dates. Until then the index stays blank instead of showing a placeholder.
