S3-compatible storage
in one desktop client
Use custom S3 endpoints for providers that expose the S3 API, then browse and transfer files with the same queue, automation, and audit tools used for Amazon S3 and R2.
S3-compatible providers all have different portals
S3-compatible storage is flexible, but daily operations can spread across vendor dashboards, endpoint notes, and CLI profiles. Comparing one provider to another is harder when every source has a different interface.
Normalize S3-compatible work in CloudPairs
CloudPairs lets you save a custom endpoint, region, bucket, access key, and secret key for S3-compatible systems. After that, the provider behaves like a browseable file source in either pane.
Why CloudPairs for S3-Compatible Storage
S3-Compatible Storage in either pane
Open S3-Compatible Storage 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.
Plan the S3-Compatible Storage workflow
Follow the provider-specific connection steps and prerequisites.

Security notes for S3-Compatible Storage
Provider-specific permissions
Use the narrowest key permissions supported by your object storage provider.

Lifecycle and retention
CloudPairs file actions follow the object-store policy, retention, and versioning rules you configure with the provider.

How to connect S3-Compatible Storage
Five steps to your first transfer. Full guide in our docs.
Confirm your provider exposes an S3-compatible endpoint and create access keys.
Choose Add Cloud Drive, then S3-Compatible Storage.
Enter endpoint URL, region if required, optional bucket, access key ID, and secret key.
Test the connection. If your provider requires path-style or special settings, confirm the endpoint documentation.
Open the connection in a pane and transfer to local folders, R2, S3, SFTP, WebDAV, or another supported source.

Common S3-Compatible Storage fixes
Connection test fails
Check endpoint format, region requirements, bucket spelling, and whether your provider expects virtual-host or path-style addressing.
Uploads fail mid-transfer
Review multipart upload support, chunk size, provider limits, and network stability.
Objects appear in an unexpected path
Check whether the bucket or prefix was included both in the endpoint and the starting path.
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. |
