What Viper FTP is
Viper FTP is a macOS file manager and FTP client for transferring files between local and remote locations. It supports FTP, FTPS, SFTP, WebDAV, Amazon S3, Google Drive, Dropbox, and YouTube uploads. Users can group servers and send files or folders to multiple destinations in one action; Folder Observer can automatically upload new items from a linked folder. The app can preview local or remote media and documents, edit remote files, compare files and folders, and manage archives. Its transfer queue tracks activity, and an action history records events. Users can password-encrypt individual files with AES-256 in CBC mode. The privacy policy says files transfer directly between the device and the selected server or cloud storage, without Viper FTP processing or storing file contents or transfer metadata. SFTP, FTPS, or HTTPS encryption is available when supported and correctly configured on the remote side. The product requires macOS 10.13 or later and is compatible with Apple silicon. Pricing includes a 5.00 USD monthly subscription for three home Macs and a 14-day trial; there is no free plan. License options cover individual, small business, and company-wide use.
