Rows with several providers are ties. Egress is what visitors or your own servers download; uploads are free everywhere here. Request fees are not priced, and the free-egress allowances of Backblaze, Wasabi, Spaces and Hetzner depend on each provider's fair-use terms.

Common questions
Does this read my storage account?
No. It uses only the stored and egress volumes (GB) you type and rate cards you can edit. It cannot see your buckets, regions, request counts or invoice. Treat every figure as a way to compare options, never as what you will be charged.
Where do the prices come from?
They are approximate public list prices as best known in 2025 for each provider's main US or EU region, shown with an as-of line, and every number is editable. Providers change packaging often, so check each pricing page before deciding.
What is not included?
Request and operation fees (PUT, GET, LIST), minimum object-retention and early-deletion charges, replication, other regions, support plans, committed-use discounts and each provider's fair-use terms. Request fees can dominate for many small objects, and Wasabi, Backblaze and others limit free egress to a ratio of what you store, so check the terms against your access pattern. Use this to compare the storage and egress lines, not to forecast the whole invoice.
Is my data uploaded anywhere?
No. The page calculates in your browser and sends nothing. The CLI reads local files and makes no network call.
