xDrives

Mount remote servers and cloud storage as native drives. A lightweight, open-source alternative to RaiDrive: no ads, no telemetry, credentials stay in the operating system keychain.

xDrives is a Tauri 2 desktop app. The backend is Rust (tokio + a shared VFS layer). The UI is TypeScript, Vite and Tailwind with a dark Slate/Zinc theme.

What it does

Source	How it mounts
SFTP (password or SSH key)	Native drive: WinFsp (Windows, Cloud Files fallback), FUSE (Linux), FUSE-T (macOS, NFS fallback)
WebDAV	Same VFS path
FTP / FTPS	Same VFS path
SMB	Same VFS path (pure-Rust SMB2/3 client)
Google Drive, OneDrive, Dropbox	OAuth2 PKCE + local loopback, then VFS
Amazon S3, MinIO, Cloudflare R2	Signed REST, then VFS

Explorer / Finder / Nautilus see a normal disk. Metadata is cached in RAM; file blocks are cached on disk with LRU so directory browsing does not stall on every round trip. Dropped connections are retried with keep-alive, exponential backoff and a small in-flight write buffer.

WinVfs (Windows Cloud Files + drive letter)
        FUSE (Linux) / FUSE-T (macOS, NFS fallback)

Passwords, private keys and OAuth tokens are never written to the config file. Connection metadata is encrypted at rest. Tokens refresh in the background.

Languages: English (default) and Polish, with automatic OS locale detection.

Prerequisites

• Rust 1.85+ (stable)
• Node.js 20+
• OS filesystem driver: none extra
  • Windows: WinFsp is bundled (correct disk size in Explorer); Cloud Files API is the fallback
  • Linux: FUSE userspace is compiled in; talks to the in-kernel /dev/fuse (no libfuse package)
  • macOS: FUSE-T is installed on first mount (Finder shows remote disk size); built-in NFSv3 is the fallback

Linux extra packages for a Tauri build: libwebkit2gtk-4.1-dev, libayatana-appindicator3-dev, librsvg2-dev.

OAuth providers (Google, Microsoft, Dropbox) require your own application client ID. Paste it in the connection wizard. xDrives does not ship third-party secrets.

Build from source

npm install
npm run tauri dev

Release installers:

npm run tauri build

Outputs:

• Windows: .msi / .exe (NSIS)
• Linux: .deb / .AppImage
• macOS: .dmg (aarch64 = Apple Silicon, x64 = Intel)

macOS Gatekeeper

GitHub Actions builds are ad-hoc signed, not notarized (that needs a paid Apple Developer ID). After copying xDrives.app from the DMG into /Applications, Finder may block it.

Open it once with a right-click → Open, or:

xattr -cr /Applications/xDrives.app
open /Applications/xDrives.app

On macOS Sequoia and later you can also allow it under System Settings → Privacy & Security.

Unit tests (no live servers required):

cd src-tauri
cargo test
