CloudDrive2 vs FolderSync

CloudDrive2 links cloud accounts and mounts them as local disks, with backup, encryption, and WebDAV features. Listed sources include Aliyun Drive, Baidu, 115, Tianyi, 123 Pan, OneDrive, Google Drive, Xunlei, WebDAV, and local folders. Its mounts support POSIX semantics on Linux and macOS and Windows security descriptors; random writes do not require downloading the full file first. The free Basic tier allows up to two cloud drives and one local mount, without Core Pro features. Core paid plans provide unlimited clouds and local mounts; Core Monthly costs 4.99 CNY a month and Core Yearly costs 49.99 CNY a year. The app can connect to Emby and Jellyfin, and the maker offers a companion plugin for both. App Pro adds HDR and Dolby Vision, DSD, ISO disc playback, AI subtitle translation, media-server client features, and VR video. CloudDrive2 also includes a WebDAV server and a gRPC API with over 200 RPC methods. The maker says account details are encrypted with the user's password and only a password hash is stored on the server. It supports Windows, Linux, macOS, Android, iOS, web UI, NAS, and Docker.

FolderSync moves files between folders on a device and cloud services or file servers, and it can also sync folders stored on the same device. One-way sync mirrors a source to a destination; two-way sync is also supported. It can transfer files between two remote locations through an Android device or desktop computer, which temporarily holds the files. Connections include Google Drive, Dropbox, OneDrive, Box and Nextcloud, along with FTP, SFTP, SMB, S3-compatible storage and WebDAV. Its V2 engine adds encryption, pre-sync change analysis, parallel transfers and Cron-based scheduling. FolderSync also supports Tasker integration and configurable events such as schedules and syncs. Encryption protects file names and contents before upload, but works only with one-way sync; a lost encryption password cannot be recovered. FolderSync says account, folder-pair and sync-log data stays on the device, while files go directly to the configured service or server. A free plan is available. Android requires version 8.0 or newer; desktop support covers Windows 10 or newer, macOS 10.15 or newer, and qualifying 64-bit x86 Linux systems.
