SmartFTP has been around since the early 2000s and has built a solid reputation as a professional-grade FTP client for Windows. It's polished, feature-rich, and targets businesses and IT professionals who need reliable, compliant file transfers. It's also not cheap — plans start at $80/year and go up to $330/year for the full feature set.
FTPie is a newer, free-to-start alternative that takes a different approach. Instead of focusing solely on file transfer, it combines FTP/SFTP with cloud storage, built-in viewers, backup scheduling, and productivity tools — all in one app.
Both are Windows-only. Both support FTP, SFTP, and cloud storage. But the pricing, feature philosophy, and target audience are quite different.
