Cloudflare R2

S3-compatible object storage with zero egress fees, built on Cloudflare's global network.

When to Use

• Storing user uploads, media files, backups, or static assets.
• Replacing AWS S3 to eliminate egress costs for read-heavy workloads.
• Serving files at the edge via Workers or public bucket access.
• Building multi-cloud storage that avoids vendor lock-in (S3 API compatible).
• Storing ML model artifacts, training data, or inference results.

Prerequisites

• Cloudflare account with R2 enabled (dashboard > R2 > subscribe).
• Wrangler CLI v3+ installed: npm install -g wrangler.
• Authenticated via wrangler login or CLOUDFLARE_API_TOKEN.
• For S3 API access: R2 API token created under R2 > Manage R2 API Tokens.
