S3 file manager
without the AWS console
Browse buckets, upload folders, and sync between S3 regions and other clouds — all from a fast dual-pane desktop app on Windows and macOS.
AWS Console is slow for everyday S3 tasks
Creating buckets in the AWS Management Console is easy — but comparing two prefixes, moving ten thousand objects, or copying S3 → Cloudflare R2 still means console friction, IAM guesswork, or CLI scripts. An amazon s3 file manager should offer visual browsing, side-by-side buckets, and a queue that survives network blips. Teams waste time tab-switching between regions and tools when they only need to upload a folder or mirror a backup. The console was built for administration, not daily file work.
Desktop S3 browser built for transfers
CloudPairs is an amazon s3 file manager for Windows 10/11 and macOS 13+ that connects with IAM access keys stored in your OS keychain. Browse any AWS region or custom endpoint in dual-pane mode, run parallel uploads with bandwidth limits, and copy S3 ↔ R2 or local disks without a staging folder. Pro adds presigned URL generation, folder sync with skip-existing, and cron automation. Start with a free 14-day Pro trial (no credit card), then $12/mo — skip the console for the work you do every day.
