VERDICT

Should I use Cyberduck?

Libre server and cloud storage browser for Mac and Windows - cyberduck.io

Worth it. Buy if you need a free, no-commitment file transfer client for Mac or Windows — it covers every major protocol. Skip it if you need scheduled, automated transfers or vendor support.

Confidence

Medium. Based on 12 public sources; thin third-party review coverage, so confidence is medium.

Gotchas - check before you buy

medium

Guess: no formal vendor support — rely on community, docs, and GitHub issues

low

Donation prompt recurs until you buy a registration key

low

Guess: App Store / Microsoft Store builds may cost money; direct download is donationware
