How do I upload files to Cloudflare R2 using Wrangler?▼

Upload files to Cloudflare R2 using the Wrangler CLI with `wrangler r2 object put bucket-name/file-path --file=./local-file`. First install Wrangler globally, authenticate with `wrangler login`, and create a bucket using `wrangler r2 bucket create bucket-name`.

Can I host static assets publicly on R2 with custom domains?▼

How do I configure CORS on R2 buckets for browser access?▼

Configure Cross-Origin Resource Sharing through Wrangler to allow browsers to access R2 objects across domains. Set CORS rules on your bucket to specify which origins, methods, and headers are permitted for seamless cross-origin requests.

Does R2 charge for data egress when hosting files?▼

No, Cloudflare R2 has zero egress fees, making it cost-effective for file hosting, static website assets, and game resource distribution. You pay only for storage and API requests, not bandwidth consumed by downloads.
