FAQ
What is the cheapest S3-compatible storage?
expand_more
The lowest minimum charge is at Contabo. If egress matters, check the Egress column: Contabo includes unlimited free egress.
Can I use these instead of Amazon S3?
expand_more
Yes. All of them support the S3 API, so rclone, restic, s3cmd, aws-cli and the AWS SDKs work once you set the endpoint.
What is egress?
expand_more
Outbound transfer: data downloaded from the bucket. Most services include some egress in the base price and charge per GB after that.
