Cloudflare R2 browser
for everyday bucket work
Browse R2 buckets beside local folders, Amazon S3, SFTP, Dropbox, OneDrive, WebDAV, Synology, and more. CloudPairs uses R2 S3-compatible credentials and keeps transfer work visible in a dual-pane Windows desktop app.
R2 object work often falls back to scripts
The Cloudflare dashboard is excellent for account and bucket settings, but teams still reach for CLI commands when they need to compare prefixes, upload folders, recover failed copies, or move objects between providers. That makes routine file work harder to inspect and repeat.
Use CloudPairs as a visual R2 file manager
CloudPairs gives R2 a familiar explorer workflow: open an R2 bucket in one pane, choose another destination in the opposite pane, then copy, drag, queue, retry, audit, or automate the job without hand-writing one-off scripts.
Why CloudPairs for Cloudflare R2
Cloudflare R2 in either pane
Open Cloudflare R2 beside a local folder or another supported connection, then compare paths before moving files.
Queue-based transfers
Uploads, downloads, folders, and cross-pane copies run through a visible queue with progress, speed, retry, and failure states.
Bulk file operations
Use multi-select, drag and drop, context menus, rename, delete, refresh, new folder, and copy-to-opposite-pane actions where the provider supports them.
Automation-ready
Create scheduled sync tasks with interval, daily, or cron timing, conflict rules, file filters, run history, and retry controls.
Usage visibility
Review transfer history in the audit log and monitor CPU, RAM, network I/O, and transfer activity from the performance dashboard.
Local credential storage
Secrets are stored through the operating system credential store where supported; provider credentials are not needed by the public website to run desktop transfers.

Security notes for Cloudflare R2
Use scoped R2 credentials
Prefer bucket-limited, least-privilege keys and rotate them from the Cloudflare dashboard if a device is lost.

CloudPairs connects to R2 through the S3-compatible HTTPS endpoint generated from your account ID.
No website-side provider secrets
R2 secrets are intended for the desktop app and OS credential store, not the public CloudPairs website.

Common Cloudflare R2 fixes
403 access denied
Check the R2 token permissions, bucket name, account ID, and whether the key can list and write objects.
Endpoint mismatch
Make sure you selected Cloudflare R2 rather than generic S3 if you want CloudPairs to generate the R2 endpoint.
Slow large transfers
Review transfer concurrency, bandwidth limit, multipart chunk size, and local network conditions.
CloudPairs vs alternatives
| Alternative | Limitation |
|---|---|
| Browser dashboards | Good for account administration, but slow for side-by-side file comparison and repeated transfer work. |
| Command-line tools | Powerful for scripted jobs, but harder to audit visually and less approachable for everyday file operations. |
| Single-provider sync apps | Useful for mirroring one account, but not designed for selective transfers across several providers. |
