# Amazon S3 vs Bunny Storage

Canonical: https://inetgeek.com/compare/amazon-s3-vs-bunny-storage/

Every value below is read from Amazon S3's and Bunny Storage's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Amazon S3 | Bunny Storage |
| --- | --- | --- |
| 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. |
| Operations price | $0.005 per 1,000 PUT, COPY, POST and LIST requests, and $0.004 per 10,000 GET and all other requests, in us-east-1. DELETE and CANCEL are free. | None. Bunny states no API fees. |

## Where they differ

### Pricing model

- Amazon S3: 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. ([source](https://aws.amazon.com/s3/pricing/))
- Bunny Storage: 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. ([source](https://bunny.net/storage/))

### Egress over allowance

- 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. ([source](https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AWSDataTransfer/current/us-east-1/index.json))
- 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. ([source](https://bunny.net/storage/))

### Storage price

- Amazon S3: $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. ([source](https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonS3/current/us-east-1/index.json))
- Bunny Storage: $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. ([source](https://bunny.net/storage/))

### Operations price

- Amazon S3: $0.005 per 1,000 PUT, COPY, POST and LIST requests, and $0.004 per 10,000 GET and all other requests, in us-east-1. DELETE and CANCEL are free. ([source](https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonS3/current/us-east-1/index.json))
- Bunny Storage: None. Bunny states no API fees. ([source](https://bunny.net/storage/))

## Which should you choose?

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.

Consider something else: 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.

Consider something else: 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.

## Documented by only one

- Free tier: Amazon S3: Yes
- Storage (entry plan): Amazon S3: None. S3 has no plans and no included storage — AWS states there is no minimum charge and you pay only for what you use, billed per GB-month from the first byte. New accounts get AWS Free Tier credits ($100 immediately, up to $200 over six months) which are spendable credit rather than a standing storage allowance.
- Minimum storage duration: Amazon S3: None on S3 Standard. 30 days on Standard-IA and One Zone-IA, 90 days on Glacier Instant and Flexible Retrieval, 180 days on Glacier Deep Archive, each with a pro-rated charge for early deletion.
- S3-compatible API: Amazon S3: Supported
- SOC 2: Amazon S3: Listed as SOC-compliant on AWS's own compliance scope page.
- ISO 27001: Amazon S3: Covered under AWS's account-wide ISO/IEC 27001:2022 certification — not scoped per-service the way SOC, HIPAA and PCI DSS are on AWS's own site.
- HIPAA: Amazon S3: Listed as a HIPAA-eligible service on AWS's own reference page.
- GDPR / data residency: Amazon S3: AWS customers can process personal data on all AWS services in compliance with GDPR, and choose the storage type and geographic region for their data.
- PCI DSS: Amazon S3: Listed as PCI DSS-compliant on AWS's own compliance scope page.

## Questions this comparison answers

**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.
