Cyberduck vs Serv-U FTP Server

Cyberduck is a libre server and cloud-storage browser for macOS and Windows. It connects to FTP, SFTP, WebDAV, SMB, OpenStack Swift, Google Cloud Storage, Amazon S3, Azure, Backblaze B2, OneDrive, SharePoint, Google Drive, Box, Dropbox, and other services. Transfers include drag-and-drop uploads and downloads, recursive directory transfers, resumable transfers, and direct copying between servers. It can synchronize local and remote directories and preview the files affected before acting. Users can edit server-side text or binary files with an external editor, and copy or open HTTP URLs; S3 support includes CDN and pre-signed URLs. Cryptomator integration provides client-side encryption, including encrypted filenames and files. SFTP supports strong ciphers, public-key authentication, and two-factor authentication. Passwords are kept in the system Keychain, and certificates are checked against its trust settings. The free software is GPL-licensed and does not require registration or an account. A personal registration key is listed at $10 a month, billed as a minimum contribution shown by the vendor; a separate registration key contribution is $10, paid once. Retaining modification dates is not supported for all protocols.

Serv-U FTP Server provides FTP and FTPS file transfers for organizations, with web and mobile interfaces for viewing, uploading, and downloading files. The FTP Server edition supports IPv4 and IPv6; an edition comparison also lists HTTP. SSL/TLS encrypts transfers. Users can pause or resume multiple and large exchanges, including files larger than 3 GB. Administrators can create users and groups, manage permissions and bandwidth, and review transfer details in a management console. They can set transfer ratios and quotas, limit concurrent sessions, and use IP blocking, reverse DNS options, and anti-hammering controls. Automation can move or delete files after transfer, or disable or reset credentials after a specified number of days. The optional Serv-U Gateway is described as keeping data out of the DMZ and helping meet listed compliance requirements. SolarWinds positions this edition for small businesses and project teams with fewer users and domains on one server. It has no free plan; the listed price is $55 a month, billed annually, and a 14-day trial is available.
