Comparison
ExpanDrive lands on Worth it, and Mountain Duck lands on Depends.
Buy it if you juggle several cloud storages across Mac, Windows, or Linux . personal use is free and it mounts S3, SFTP, or SharePoint as a real drive.
Buy it if you need S3, SFTP, or B2 storage mounted as a real disk and native sync apps don't cover you.
| Compare | ExpanDrive | Mountain Duck |
|---|---|---|
| Verdict | Worth it | Depends |
| Best for | Multi-cloud jugglers (Drive + S3 + Dropbox) | Freelancers mounting S3/SFTP/B2 as a disk |
| Who it's not for | Single-cloud users . the provider's own free app already does this | Anyone happy with native Dropbox/Drive/OneDrive clients |
| Privacy | TLS everywhere, credentials in the OS keychain, OAuth-only sign-in; older builds had disclosed flaws, so run the current release.³ | Two high-severity 2025 CVEs around TLS certificate handling, since patched; no dedicated security page found. |
| Support quality | No support-quality evidence in sources | Capterra customer service score 4.0/5 |
| Public sentiment | Reviewers praise easy multi-cloud mounting and near-native speeds; Macworld found version 7 imperfect.⁵ | Users love cloud storage appearing as a local disk, but stability complaints and the pricing-model switch split sentiment sharply. |
| Biggest gotcha | Older builds have disclosed security issues . only the current release is patched.³ | Pricing model flipped: App Store v5 is subscription; a forum thread calls the switch 'actual scam' |
