DiscoDrive Apps

English · Deutsch · Українська · Français · Español · Русский · Српски

DiscoDrive client apps — for all your devices. A background sync daemon, a desktop client and native mobile apps in one repository.

This is the client repository for the DiscoDrive server — your own private cloud for files, calendars, contacts, tasks, music and books.

Cross-platform: macOS, Windows, Linux and Android. A single Makefile builds the right variant for the right OS.

Features

🔄 Sync daemon

Background two-way folder sync, Dropbox-style: a local folder ↔ the server. What to sync — a single folder or the whole storage root — is configured on the server.

• Headless — runs without a GUI, ideal for servers and NAS.
• Menu bar / tray (build with TRAY=1) — status icon and quick actions.
• E2E vault — client-side encryption in a Cryptomator-compatible format: files are encrypted on the device before they are sent.
• Never lose data — if the same file changes in two places at once, a conflict copy is created instead of a silent overwrite.
• Auto-start on login.

🖥️ Desktop client

A cross-platform GUI app (macOS, Windows, Linux) with an on-demand model.

• Browse the whole storage — the entire file tree is visible.
• Upload and download files and folders, manage E2E vaults right from the app.
• Pair with the server in a couple of clicks.
• System tray and auto-start.
• 7 interface languages — English, German, Ukrainian, French, Spanish, Russian and Serbian.

📱 Mobile apps

• Full clients — android-discodrive (Android) and ios (iOS): on-demand access to the whole storage.
• Folder-sync — android-fastsync and ios-fastsync: minimal apps for full sync of a chosen folder.

Prebuilt releases

Prebuilt binaries for Linux, Windows and macOS (daemon and desktop client) and an .apk for Android are published on the releases page:

👉 github.com/kosmosoid/discodrive-apps/releases

• macOS (.dmg) and Windows (.exe + installer) are unsigned. On first launch Gatekeeper (macOS) or SmartScreen (Windows) will show a warning.
• iOS is not included in releases (you need to build it yourself and install it on an iPhone via Xcode).

Building from source

If the prebuilt binaries aren't enough or you need a different platform — build it yourself. make doctor shows which tools are installed and which are missing.

What you need

The commands and tools below assume macOS as the host system: the daemon cross-compiles on any OS, while the desktop client is built on macOS — a native .dmg plus Windows and Linux via cross-build (Windows directly, Linux in a Docker container). On Windows/Linux themselves the toolset differs (see the note below).

Common (any platform):

• Go 1.25+ — required for everything.
• Node.js — to build the desktop client's frontend.
• Desktop client toolchain — go install github.com/wailsapp/wails/v2/cmd/wails@latest.

Desktop client (host — macOS):

• makensis (brew install makensis) — Windows installers (NSIS), target desktop-windows.
• Docker — Linux build in a Debian container with WebKitGTK, target desktop-linux.

Mobile apps:

• Xcode + XcodeGen — Apple apps (macOS only).
• Android SDK + NDK + Gradle, gomobile — Android.

Building off macOS. The daemon builds anywhere, no caveats. The desktop client for Linux/Windows can also be built natively — directly via wails build with the platform's system dependencies (on Linux — GTK 3 and WebKit2GTK dev packages; on Windows — WebView2); there are no dedicated make targets for that. The desktop-linux target (Docker) works from any host.

Daemon

make daemon                       # for the current OS → dist/<os>-<arch>/discodrive
make daemon OS=linux ARCH=arm64   # cross-compile (pure Go, no CGO)
make daemon TRAY=1                # with menu bar / tray (CGO)
make daemon-all                   # all OSes at once

Desktop client

make desktop              # macOS app (universal)
make dmg-desktop-macos    # macOS .dmg                  → dist/DiscoDrive-<version>-macos.dmg
make desktop-windows      # Windows .exe + NSIS         → dist/windows/   (cross-built from macOS)
make desktop-linux        # Linux (via Docker, any host) → dist/linux/

Mobile apps

make app-android            # Android, full UI
make app-android-fastsync   # Android, folder-sync
make app-macos              # macOS app (Xcode)
make app-ios                # iOS app (Xcode)
make bind-ios               # gomobile binding for Apple only
make bind-android           # gomobile binding for Android only
