Cloudflare R2 is an object storage service compatible with Amazon S3 API enabling developers to store large amounts of data with zero egress fees for data leaving the cloud. The platform integrates natively with other Cloudflare services including Workers for compute and Images for image optimization making it ideal for Cloudflare-based architectures. R2 provides highly durable storage for a fraction of the cost of traditional cloud storage providers. Developers migrate to R2 to avoid egress fees while maintaining S3-compatible tooling and workflows.
