Verdicts

Bunny Storage

$0.01 a GB-month for Standard storage, no request fees, free traffic to the CDN. Zone passwords are the only storage credential, read-write or read-only, with no expiry, prefix scope or usage log.

Wasabi Hot Cloud Storage

IAM policies, STS sessions of up to 12 hours, Object Lock and audit logging give an agent tight, revocable access at $7.99 a TB-month with no egress or request fees. No request limits are published with numbers for the S3 API, there is no OpenAPI file, and billing assumes 1 TB and 90 days of storage as minimums.

Before you call either

Bunny Storage

  1. Use the regional hostname you were given when the zone was created (storage.bunnycdn.com is Frankfurt). Other regions return a 401
  2. Send the body as raw bytes with --data-binary. Base64 or form encoding gets a 401
  3. Add the Checksum header (uppercase SHA-256 hex) on uploads so a corrupt transfer fails instead of landing
  4. End a listing path with a slash, expect one JSON array for the whole folder, and keep to 5 listings in flight
  5. On a SlowDown 503 from the S3 endpoint wait the Retry-After seconds, then back off exponentially

Wasabi Hot Cloud Storage

  1. Use the bucket's own regional endpoint, such as s3.eu-central-2.wasabisys.com. The docs say a wrong endpoint allows GET but not PUT or DELETE
  2. Ask for a sub-user key with a policy limited to one bucket, or an STS session. A root key has full access, billing included
  3. Avoid short-lived objects. Each object deleted before 90 days is billed for the remaining days, and objects under 4 KB bill as 4 KB
  4. Keep monthly downloads at or below the stored volume, the limit of the free egress policy
  5. Call https:// endpoints explicitly. The S3 API also accepts plain HTTP
  6. For the MCP beta, type https://mcp.wasabisys.dev/s3 from the page text. The links in the docs table point at a different host
