Amazon S3 vs Bunny Storage
SEPT 2026 auditA comparison of Amazon S3 and Bunny Storage built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose Amazon S3 if…
Workloads already inside AWS, where keeping data in the same region as the compute avoids the transfer charges that dominate an object storage bill.
Editorial · Palash Bagchi · approved
Choose Bunny Storage if…
Assets served from a CDN, where paying per replicated region buys latency you would otherwise build yourself — and traffic to Bunny's CDN costs nothing.

Consider something else if…
- Amazon S3: Egress is the cost that decides this category and S3 charges for it, where R2, Wasabi and Tigris do not. Prices also vary by region, so a figure quoted anywhere is only true for the region it was read in.
- Bunny Storage: Replication is the price axis, so multi-region storage costs a multiple of single-region rather than a premium, and it is a CDN origin rather than a general-purpose S3 endpoint.

At a glance.
| Criterion | Amazon S3 | Bunny Storage |
|---|---|---|
| Pricing | ||
| Pricing model | Per region and per storage class, with storage, requests, retrievals, data transfer and management features each metered separately. AWS states there is no minimum charge, and bills storage in binary gigabytes — 1 GB is 2^30 bytes, not 10^9. | Per region rather than per gigabyte alone: replication is the price axis, so cost scales with how many of Bunny's regions hold a copy. True pay-as-you-go with a $1 monthly minimum and no commitments. |
| Egress over allowance | $0.09 per GB for the first 10 TB a month out to the internet, after a free 100 GB aggregated globally. It falls to $0.085 above 10 TB, $0.07 above 50 TB and $0.05 above 150 TB. This is AWS's outbound data transfer rate rather than an S3-specific one — the charge that R2, Wasabi and Tigris do not levy at all. | Free to Bunny's own CDN, and no API fees or API egress charges. Bunny prices storage by replication rather than by transfer. |

| Storage price | $0.023 per GB-month for S3 Standard, first 50 TB, in us-east-1. S3 prices vary by region; this and every other S3 figure on the site is that region. | $0.01 per GB per month on Standard HDD for up to two regions, then $0.005 per additional region up to nine. Edge SSD is $0.02 per GB per region across up to fifteen. Three regions on Standard is $0.025 per GB. |

Egress over allowance: Amazon S3 or Bunny Storage?
Amazon S3: $0.09 per GB for the first 10 TB a month out to the internet, after a free 100 GB aggregated globally. It falls to $0.085 above 10 TB, $0.07 above 50 TB and $0.05 above 150 TB. This is AWS's outbound data transfer rate rather than an S3-specific one — the charge that R2, Wasabi and Tigris do not levy at all.
Bunny Storage: Free to Bunny's own CDN, and no API fees or API egress charges. Bunny prices storage by replication rather than by transfer.
Should I choose Amazon S3 or Bunny Storage?
Pick Amazon S3 if Workloads already inside AWS, where keeping data in the same region as the compute avoids the transfer charges that dominate an object storage bill.
Pick Bunny Storage if Assets served from a CDN, where paying per replicated region buys latency you would otherwise build yourself — and traffic to Bunny's CDN costs nothing.
