R2

Cloudflare R2: S3-compatible object storage that delivers zero egress fees and global performance.

R2 is Cloudflare's global object storage solution, engineered to eliminate the costly egress fees common with providers like AWS S3. It offers an S3-compatible API, ensuring seamless integration with existing tools and workflows. Developers store unstructured data (e.g., web assets, data lakes) at a competitive rate: Standard Storage starts at $0.015/GB-month. R2 integrates natively with Cloudflare Workers, allowing you to build and deploy high-performance, edge-based applications across Cloudflare's network of 330+ data centers.
