Cloudflare R2

S3-compatible object storage with no egress fees. Cheaper than S3 for high-bandwidth use cases.

Cloudflare R2 is S3-compatible storage with zero egress fees. Major cost saving for high-bandwidth apps (video streaming, image-heavy).

Full walkthrough being written.

When to pick over S3

• Bandwidth-heavy apps where S3 egress fees are significant.
• You’re already on Cloudflare for CDN.
• API parity with S3 (use the same SDKs).

Setup

R2_ACCOUNT_ID, R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_BUCKET in vly secrets. Use AWS S3 SDK with R2’s endpoint.
