What are the best S3-compatible object storage options for chat apps?

Cloudflare R2 for small scale (free 10GB), Backblaze B2 for backups/large volumes. Avoid Wasabi under 1TB; skip self-hosted MinIO unless you love ops.

Is Cloudflare R2 really free and unlimited?

10GB storage free, 10M Class A ops/month free, no egress. Perfect for prototypes; bills kick in at scale.

How to cache Wasabi public files with Cloudflare?

Proxy via /api/media/*, set CF cache rules: edge TTL 1 year, eligible for cache. Hits bypass backend forever.
