Ultra-portable SFTP server for Windows and Linux

Syncplify.me MicroServer!

MicroServer! is an ultra-portable SFTP server for Windows and Linux, supporting both 32 and 64 bit x86 and ARM architectures. It’s just a few megabytes in size, and can be run from a USB stick, with no installation at all. And it’s totally free for non-commercial use (read more about Syncplify.me MicroServer! v3's license at the bottom of this page).

It’s mainly suitable for one-time or sudden secure file transfer jobs from/to machines where you don’t want to install a full-featured Server!, but you still need the security of SFTP.

As such, MicroServer! comes with a number of limitations that users have to be aware of:

It only supports one user profile, and one root folder

It handles incoming connections only from one client at a time

No protocol nor security settings (KEx, HMAC, Crypto-algos) can be configured

Every time you run it, it will generate and use a new RSA host key

Please keep in mind that if your goal is to deploy and use an SFTP server in a corporate environment for long term use (more than just a few minutes) then this is not what you need; to accomplish that you'll need the full power of Syncplify.me Server!
