What's included

Everything you'd expect
from a commercial server

No subscriptions, no cloud dependencies, no telemetry. Runs entirely on your hardware.

GUI Management Console
Clean desktop interface for managing users, certificates, settings, and monitoring live activity.
Windows Service
Runs as a proper Windows Service — survives reboots, runs without anyone logged in, auto-restarts on failure.
Per-User Permissions
Fine-grained access control: read, write, delete, rename, mkdir. Chroot jailing, IP allowlists, bandwidth limits.
PFX Certificate Support
Import your own PFX/P12 certificates or generate self-signed keys. Full TLS host key management built in.
Real-Time Monitoring
Live dashboard with active sessions, transfer activity feed, byte counts, and failed auth tracking.
Public Key Auth
SSH public key authentication alongside password auth. Configurable ciphers and key exchange methods.

A note on the "free" part: We believe software should be free to try. The welcome banner restriction is our way of asking nicely rather than putting up paywalls. If the server saves you time or earns you money — buying a license is the right thing to do.

Questions

Frequently asked

Yes. Every feature works — unlimited users, Windows Service, certificates, GUI, all of it. The only restriction is the SFTP welcome message, which is locked to "UNREGISTERED VERSION". For most users this is invisible — SFTP clients often don't display it. The license just removes that restriction.
You receive a license.dat file. Drop it into C:\ProgramData\SFTPServerPro\ and restart the service. No internet required, no activation servers, no phone-home. It just works.
Yes. One license covers all machines you personally operate. If you're deploying it to customers or reselling, please purchase one license per deployment.
It downloads immediately after payment and is also emailed automatically. If you don't receive the email within an hour, use the contact form below and include your PayPal transaction ID — we'll sort it out promptly.
Yes. Windows 10, Windows 11, and Windows Server 2019/2022. Administrator rights required for port 22 — for other ports (2222, 8022, etc.) standard user rights are sufficient.
Any standard SFTP client: WinSCP, FileZilla, Cyberduck, the command-line sftp tool, rsync over SSH, and programmatic clients in Python, Node.js, Java, etc.
