CrushFTP vs FileZilla Client

CrushFTP is a file transfer server for secure transfers across a range of operating systems. Administrators can manage users, preferences, reports and plugins in a web browser. Supported secure protocols include FTPES, FTPS, SFTP, SCP and HTTPS; authentication options include LDAP, RADIUS, SAML and OAuth, with MFA/OTP validation available. Files can be encrypted in transit and at rest using PGP. The server connects to storage and services including S3, Google Drive, Azure, Dropbox, OneDrive, SharePoint, Box, SMB and Hadoop. Enterprise tools include scheduling, monitoring, automated reporting, DMZ capability and high availability through session replication. CrushSync synchronizes files in real time and can send changed portions of large files with compression. The web interface supports resumable transfers, WebDAV clients for iOS and Android, thumbnails, slideshows and movie playback. The full normal-license download has a 30-day trial; the site says only CrushFTP 11 is currently supported. Plans include a Small Business option at $70 a month, listed as a perpetual license.

FileZilla Client is a free FTP solution for file transfers, with support for FTP, FTPS, and SFTP. It is available for Linux, macOS, and Windows. The project presents FileZilla Client separately from FileZilla Server, FileZilla Pro, and RemoteDrive, so those products should not be assumed to be part of the Client. Documentation includes installation instructions for Windows, Linux, and Mac OS X, plus tutorials, usage guidance, and help with connection, transfer, and network configuration problems. The Wiki also includes guidance for key-based SFTP authentication. Support resources include a community forum, Wiki, FAQ, support section, and contact page. The project site links to source code, an issue tracker, nightly builds, translations, and version history. FileZilla Pro is a separate product whose overview lists support for cloud services including S3, Google Drive, and OneDrive. No paid price or billing schedule is stated for the Client, and no free-tier limits are stated.
