| Regions | 6 location hints (best effort); EU, US and FedRAMP jurisdictions | 43, including 13 in Europe, plus dual-regions and ASIA, EU and US multi-regions |
| Bottom line | From its public pages, Cloudflare R2 removes the egress fee and keeps billing simple, with a permanent free tier and no minimums on Standard. Versioning, the S3 Object Lock API and replication are not implemented, so it suits serving data more than strict retention. | From its public pages, Google Cloud Storage has nearly every protection and compliance feature we score, publishes every price in USD and keeps a permanent free tier. Internet egress, billed per GiB, is the main cost, and S3 support is an interoperability mode. |
