COMMUNITY

From the forums

Reddit feedback in r/selfhosted is strongly positive about R2 for media, backups and static assets, especially when repeated downloads make egress more important than storage price. Developers appreciate the S3 API and the ability to keep a small project within the free allowance. The practical complaints are setup friction with some S3-compatible tools, occasional checksum or integration errors, and the need to understand Cloudflare's account and billing model before using it as a primary storage layer.
