Cloudflare R2
An S3-compatible object storage service from Cloudflare with zero egress fees, integrated with the Cloudflare global edge network.
Summary
An S3-compatible object storage service from Cloudflare with zero egress fees, integrated with the Cloudflare global edge network.
R2 directly addresses the Egress Cost pain point that shapes S3 architecture decisions. By eliminating egress charges, R2 changes the economics of multi-cloud, CDN, and data distribution workloads that are prohibitively expensive on AWS S3.
- R2 is S3-compatible but does not support all S3 features (e.g., Object Lock, some lifecycle features). Test compatibility thoroughly before migration.
- Zero egress does not mean zero cost. Storage costs, Class A/B operation costs, and Workers integration costs still apply.

Definition
Cloudflare's S3-compatible object storage with zero egress fees, globally distributed with Cloudflare's edge network.
Egress costs from AWS S3 can dominate total cloud spend. R2 eliminates egress fees entirely, making multi-cloud and CDN-fronted object storage architectures economically viable.
Egress-free media storage, multi-cloud data distribution, CDN-fronted object storage, S3-compatible storage with predictable costs.
