In their own words
ExpanDrive
ExpanDrive mounts cloud storage and protocol endpoints as desktop drives, letting you access files through Finder, Explorer, and other applications. Files stream on demand rather than syncing folders, with local caching and an option to pin files for offline access. Listed connections include Amazon S3, Backblaze B2, Box, Dropbox, Google Drive, OneDrive, SharePoint, Nextcloud, FTP, SFTP, WebDAV, and others. It runs on macOS, Windows, and Linux. Server Edition can operate as a headless service on Windows Server and Linux, expose mounted storage as a Windows SMB share, and includes a command line for managing mounts and connections. ExpanDrive says connections use TLS and credentials are kept in the local operating system credential store. Plain FTP sends credentials and file contents in the clear; FTPS or SFTP is recommended for sensitive connections. The Free plan is free, billed forever. Business is $29 a month, billed monthly; Enterprise pricing is custom.
