## Verdicts

**Bunny Storage.** $0.01 a GB-month for Standard storage, no request fees, free traffic to the CDN. Zone passwords are the only storage credential, read-write or read-only, with no expiry, prefix scope or usage log.

**Cloudflare R2.** Free egress and a free tier of 10 GB-month plus 1 million writes a month. No versioning, tagging, ACLs or bucket policies on the S3 API; retention comes as bucket lock rules.

## Before you call either

### Bunny Storage

1. Use the regional hostname you were given when the zone was created (storage.bunnycdn.com is Frankfurt). Other regions return a 401
2. Send the body as raw bytes with --data-binary. Base64 or form encoding gets a 401
3. Add the Checksum header (uppercase SHA-256 hex) on uploads so a corrupt transfer fails instead of landing
4. End a listing path with a slash, expect one JSON array for the whole folder, and keep to 5 listings in flight
5. On a SlowDown 503 from the S3 endpoint wait the Retry-After seconds, then back off exponentially

### Cloudflare R2

1. Set region to `auto` and the endpoint to https://<account-id>.r2.cloudflarestorage.com. `us-east-1` also works, other region names fail
2. Ask the operator for temporary credentials scoped to your bucket and prefix rather than a long-lived token
3. For public reads put a custom domain or an r2.dev subdomain on the bucket; presigned URLs only sign the S3 hostname
4. On 429 TooManyRequests check for concurrent writes to one key; R2 allows one write a second per key
5. Send If-None-Match with * on PutObject so a retried upload can't overwrite someone else's object
