FTPGrab is a CLI application written in Go to grab your files from a remote FTP or SFTP server to your NAS, server or computer . With Go, this app can be used across many platforms and architectures. This support includes Linux, FreeBSD, macOS and Windows on architectures like amd64, i386, ARM and others.
Because FTPGrab is distributed as an independent binary, it is ideal for those with a seedbox to grab your files periodically to your Synology, Qnap, D-Link and others NAS.
It is free and open source and always will be !
