Pros & cons
Our editorial assessment — not vendor-stated facts.
Pros
- No egress fees — a fraction of S3 cost for read-heavy workloads
- S3-compatible, so most tooling works unchanged
- Generous free tier (10 GB storage)
- First-class Workers/CDN integration
Cons
- Fewer storage classes and features than S3
- Class A/B operation charges still apply
- Best value assumes you use Cloudflare's ecosystem
Pricing
Usage-based: about $0.015/GB-month of storage plus per-million Class A/B operation charges, and $0 egress on all reads. A monthly free tier covers 10 GB of storage and a baseline of operations. The zero-egress model is the whole point — cheapest when bandwidth would dominate an S3 bill.
Who should use Cloudflare R2?
Teams serving lots of downloads, images or video who are punished by S3 egress fees, especially anyone already using Cloudflare Workers or CDN.
