Mullvad VPN desktop and mobile app
Welcome to the Mullvad VPN client app. This repository contains all the source code for the desktop and mobile versions of the app. For desktop this includes the system service/daemon (mullvad-daemon), a graphical user interface (GUI) and a command line interface (CLI). The Android app uses the same backing system service for the tunnel and security but has a dedicated frontend in android/. iOS consists of a completely standalone implementation that resides in ios/.
Releases
There are built and signed releases for macOS, Windows, Linux and Android available on our website and on Github. The Android app is also available on Google Play and F-Droid and the iOS version on App Store.
You can find our code signing keys as well as instructions for how to cryptographically verify your download on Mullvad's Open Source page.
Platform/OS support
These are the operating systems and their versions that the app officially supports. It might work on many more versions, but we don't test for those and can't guarantee the quality or security.
| OS/Platform | Supported versions |
|---|---|
| Windows | 7, 8.1 and 10 |
| macOS | The three latest major releases |
| Linux (Ubuntu) | The two newest LTS releases and the two newest non-LTS releases |
| Linux (Fedora) | The versions that are not yet EOL |
| Linux (Debian) | The versions that are not yet EOL |
| Android | The four latest major releases |
| iOS | 13 and newer |
On Linux we test using the Gnome desktop environment. The app should, and probably does work in other DEs, but we don't regularly test those.
Features
Here is a table containing the features of the app across platforms. This reflects the current state of latest master, not necessarily any existing release.
| Windows | Linux | macOS | Android | iOS | |
|---|---|---|---|---|---|
| OpenVPN | ✓ | ✓ | ✓ | ||
| WireGuard | ✓ | ✓ | ✓ | ✓ | ✓ |
| OpenVPN over Shadowsocks | ✓ | ✓ | ✓ | ||
| Optional local network access | ✓ | ✓ | ✓ | ✓ | ✓* |
* The local network is always accessible on iOS with the current implementation
Security and anonymity
This app is a privacy preserving VPN client. As such it goes to great lengths to stop traffic leaks. And basically all settings default to the more secure/private option. The user has to explicitly allow more loose rules if desired. See the dedicated security document for details on what the app blocks and allows, as well as how it does it.
Checking out the code
This repository contains submodules needed for building the app. However, some of those submodules also have further submodules that are quite large and not needed to build the app. So unless you want the source code for OpenSSL, OpenVPN and a few other projects you should avoid a recursive clone of the repository. Instead clone the repository normally and then get one level of submodules:
git clone https://github.com/mullvad/mullvadvpn-app.git
cd mullvadvpn-app
git submodule update --init
We sign every commit on the master branch as well as our release tags. If you would like to verify your checkout, you can find our developer keys on Mullvad's Open Source page.
Binaries submodule
This repository has a git submodule at dist-assets/binaries. This submodule contains binaries and build scripts for third party code we need to bundle with the app. Such as OpenVPN, Shadowsocks etc.
This submodule conforms to the same integrity/security standards as this repository. Every merge commit should be signed. And this main repository should only ever point to a signed merge commit of the binaries submodule.
See the binaries submodule's README for more details about that repository.
Install toolchains and dependencies
Follow the instructions for your platform, and then the All platforms instructions.
These instructions are probably not complete. If you find something more that needs installing on your platform please submit an issue or a pull request.
Windows
The host has to have the following installed:
-
Microsoft's Build Tools for Visual Studio 2019 (a regular installation of Visual Studio 2019 Community edition works as well).
-
Windows 10 SDK.
-
msbuild.exeavailable in%PATH%. If you installed Visual Studio Community edition, the binary can be found under:C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\amd64 -
bashinstalled as well as a few base unix utilities, includingsedandtail. The environment coming with Git for Windows works fine. -
gccfor CGo.
Linux
Debian/Ubuntu
# For building the daemon
sudo apt install gcc libdbus-1-dev
# For building the installer
sudo apt install rpm
Fedora/RHEL
# For building the daemon
sudo dnf install dbus-devel
# For building the installer
sudo dnf install rpm-build
Android
These instructions are for building the app for Android under Linux.
Download and install the JDK
sudo apt install zip default-jdk
Download and install the SDK
The SDK should be placed in a separate directory, like for example ~/android or /opt/android. This directory should be exported as the $ANDROID_HOME environment variable.
cd /opt/android # Or some other directory to place the Android SDK
export ANDROID_HOME=$PWD
wget https://dl.google.com/android/repository/commandlinetools-linux-6609375_latest.zip
unzip commandlinetools-linux-6609375_latest.zip
./tools/bin/sdkmanager "platforms;android-29" "build-tools;29.0.3" "platform-tools"
If sdkmanager fails to find the SDK root path, pass the option --sdk_root=$ANDROID_HOME to the command above.
Download and install the NDK
The NDK should be placed in a separate directory, which can be inside the $ANDROID_HOME or in a completely separate path. The extracted directory must be exported as the $ANDROID_NDK_HOME environment variable.
cd "$ANDROID_HOME" # Or some other directory to place the Android NDK
wget https://dl.google.com/android/repository/android-ndk-r20b-linux-x86_64.zip
unzip android-ndk-r20b-linux-x86_64.zip
cd android-ndk-r20b
export ANDROID_NDK_HOME="$PWD"
Docker
Docker is required to build wireguard-go for Android. Follow the installation instructions for your distribution.
Configuring Rust
These steps has to be done after you have installed Rust in the section below:
Install the Rust Android target
Some environment variables must be exported so that some Rust dependencies can be cross-compiled correctly:
export NDK_TOOLCHAIN_DIR="$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin"
export AR_aarch64_linux_android="$NDK_TOOLCHAIN_DIR/aarch64-linux-android-ar"
export AR_armv7_linux_androideabi="$NDK_TOOLCHAIN_DIR/arm-linux-androideabi-ar"
export AR_x86_64_linux_android="$NDK_TOOLCHAIN_DIR/x86_64-linux-android-ar"
export AR_i686_linux_android="$NDK_TOOLCHAIN_DIR/i686-linux-android-ar"
export CC_aarch64_linux_android="$NDK_TOOLCHAIN_DIR/aarch64-linux-android21-clang"
export CC_armv7_linux_androideabi="$NDK_TOOLCHAIN_DIR/armv7a-linux-androideabi21-clang"
export CC_x86_64_linux_android="$NDK_TOOLCHAIN_DIR/x86_64-linux-android21-clang"
export CC_i686_linux_android="$NDK_TOOLCHAIN_DIR/i686-linux-android21-clang"
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android
Set up cargo to use the correct linker and archiver
This block assumes you installed everything under /opt/android, but you can install it wherever you want as long as the ANDROID_HOME variable is set accordingly.
Add to ~/.cargo/config.toml:
[target.aarch64-linux-android]
ar = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ar"
linker = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang"
[target.armv7-linux-androideabi]
ar = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ar"
linker = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang"
[target.x86_64-linux-android]
ar = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/x86_64-linux-android-ar"
linker = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/x86_64-linux-android21-clang"
[target.i686-linux-android]
ar = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/i686-linux-android-ar"
linker = "/opt/android/android-ndk-r20b/toolchains/llvm/prebuilt/linux-x86_64/bin/i686-linux-android21-clang"
Signing key for release APKs (optional)
In order to build release APKs, they need to be signed. First, a signing key must be generated and stored in a keystore file. In the example below, the keystore file will be /home/user/app-keys.jks and will contain a key called release.
keytool -genkey -v -keystore /home/user/app-keys.jks -alias release -keyalg RSA -keysize 4096 -validity 10000
Fill in the requested information to generate the key and the keystore file. Suppose the file was protected by a password keystore-password and the key with a password key-password. This information should then be added to the android/keystore.properties file:
keyAlias = release
keyPassword = key-password
storeFile = /home/user/app-keys.jks
storePassword = keystore-password
All platforms
-
Make sure to use a recent version of
bash. The default version in macOS (3.2.57) isn't supported. -
Get the latest stable Rust toolchain via rustup.rs.
-
This can be skipped for Android builds.
Get the latest version 14 release of Node.js and the latest version of npm. After installing Node.js the latest version of npm can be installed by running:
npm install -g npmmacOS
brew install node
Linux
Just download and unpack the
node-v14.xxxx.tar.xztarball and add itsbindirectory to yourPATH.Windows
Download the Node.js installer from the official website.
-
Install Go (ideally version
1.16) by following the official instructions. Newer versions may work too. Sincecgois being used, make sure to have a C compiler in your path. On Windowsmingw'sgcccompiler should work.gccon most Linux distributions should work, andclangfor MacOS.
Building and packaging the app
Desktop
The simplest way to build the entire app and generate an installer is to just run the build script. --dev-build is added to skip some release checks and signing of the binaries:
./build.sh --dev-build
This should produce an installer exe, pkg or rpm+deb file in the dist/ directory.
Building this requires at least 1GB of memory.
macOS
By default a universal app is built on macOS. To build specifically for x86_64 or ARM64 add --target x86_64-apple-darwin or --target aarch64-apple-darwin.
Apple ARM64 (aka Apple Silicon)
Due to inability to build the management interface proto files on ARM64 (see this issue) the Apple ARM64 build must be done in 2 stages:
- Build management interface proto files on a non-ARM64 platform
- Use the built proto files during the main build by setting the
MANAGEMENT_INTERFACE_PROTO_BUILD_DIRenvironment variable to the path the proto files
To build the management interface proto files there is a script (execute it on a non-ARM64 platform):
cd gui/scripts
npm ci
./build-proto.sh
After that copy the files from gui/src/main/management_interface/ and gui/build/src/main/management_interface/ directories into a single directory on your Apple Silicon Mac, and set the value of MANAGEMENT_INTERFACE_PROTO_BUILD_DIR to that directory while running the main build.
Make sure that the version of Go on your Mac is 1.16 (the first version to add support for Apple Silicon) or newer.
Install protobuf by running:
brew install protobuf
When all is done run the main build. Assuming that you copied the proto files into /tmp/management_interface_proto directory, the build command will look as follows:
MANAGEMENT_INTERFACE_PROTO_BUILD_DIR=/tmp/management_interface_proto ./build.sh --dev-build
If you want to build each component individually, or run in development mode, read the following sections.
Android
Running the build-apk.sh script will build the necessary Rust daemon for all supported ABIs and build the final APK:
./build-apk.sh
You may pass a --dev-build to build the Rust daemon and the UI in debug mode and sign the APK with automatically generated debug keys:
./build-apk.sh --dev-build
If the above fails with an error related to compression, try allowing more memory to the JVM:
echo "org.gradle.jvmargs=-Xmx4608M" >> ~/.gradle/gradle.properties
./android/gradlew --stop
Building and running mullvad-daemon on desktop
-
Firstly, on MacOS and Linux, one should source
env.shto set the default environment variables.source env.sh -
On Windows, make sure to start bash first (e.g., Git BASH). Then build the C++ libraries:
./build_windows_modules.sh --dev-build
-
Build the system daemon plus the other Rust tools and programs:
cargo build
-
Copy the OpenVPN and Shadowsocks binaries, and our plugin for it, to the directory we will use as resource directory. If you want to use any other directory, you would need to copy even more files.
cp dist-assets/binaries/<platform>/{openvpn, sslocal}[.exe] dist-assets/ cp target/debug/*talpid_openvpn_plugin* dist-assets/
-
On Windows, also copy
wintun.dllto the build directory:cp dist-assets/binaries/x86_64-pc-windows-msvc/wintun.dll target/debug/
-
On Windows, the daemon must be run as the SYSTEM user. You can use PsExec to launch an elevated bash instance before starting the daemon in it:
psexec64 -i -s bash.exe -
Run the daemon with verbose logging (from the root directory of the project):
sudo MULLVAD_RESOURCE_DIR="./dist-assets" ./target/debug/mullvad-daemon -vvLeave out
sudoon Windows. The daemon must run as root since it modifies the firewall and sets up virtual network interfaces etc.
Environment variables controlling the execution
-
TALPID_FIREWALL_DEBUG- Helps debugging the firewall. Does different things depending on platform:- Linux: Set to
"1"to add packet counters to all firewall rules. - macOS: Makes rules log the packets they match to the
pflog0interface.- Set to
"all"to add logging to all rules. - Set to
"pass"to add logging to rules allowing packets. - Set to
"drop"to add logging to rules blocking packets.
- Set to
- Linux: Set to
-
TALPID_FIREWALL_DONT_SET_SRC_VALID_MARK- Forces the daemon to not setsrc_valid_markconfig on Linux. The kernel config option is set because otherwise strict reverse path filtering may prevent relay traffic from reaching the daemon. Ifrp_filteris set to1on the interface that will be receiving relay traffic, andsrc_valid_markis not set to1, the daemon will not be able to receive relay traffic. -
TALPID_DNS_MODULE- Allows changing the method that will be used for DNS configuration on Linux. By default this is automatically detected, but you can set it to one of the options below to choose a specific method:"static-file": change the/etc/resolv.conffile directly"resolvconf": use theresolvconfprogram"systemd": use systemd'sresolvedservice through DBus"network-manager": useNetworkManagerservice through DBus
-
TALPID_FORCE_USERSPACE_WIREGUARD- Forces the daemon to use the userspace implementation of WireGuard on Linux. -
TALPID_DNS_CACHE_POLICY- On Windows, this changes how DNS is configured:1: The default. This sets a global list of DNS servers thatdnscachewill use instead of the servers specified on each interface.0: Only set DNS servers on the tunnel interface. This will misbehave if local custom DNS servers are used.
-
TALPID_DISABLE_OFFLINE_MONITOR- Forces the daemon to always assume the host is online. -
MULLVAD_MANAGEMENT_SOCKET_GROUP- On Linux and macOS, this restricts access to the management interface UDS socket to users in the specified group. This means that only users in that group can use the CLI and GUI. By default, everyone has access to the socket.
Setting environment variable
-
On Windows, one can use
setxfrom an elevated shell, like sosetx TALPID_DISABLE_OFFLINE 1 /m
For the change to take effect, one must restart the daemon
sc.exe stop mullvadvpn sc.exe start mullvadvpn -
On Linux, one should edit the systemd unit file via
systemctl edit mullvad-daemon.serviceand edit it like so[Service] Environment="TALPID_DISABLE_OFFLINE_MONITOR=1"For the change to take effect, one must restart the daemon
sudo systemctl restart mullvad-daemon
-
On macOS, one can use
launchctllike sosudo launchctl setenv TALPID_DISABLE_OFFLINE_MONITOR 1
For the change to take effect, one must restart the daemon
launchctl unload -w /Library/LaunchDaemons/net.mullvad.daemon.plist launchctl load -w /Library/LaunchDaemons/net.mullvad.daemon.plist
Building and running the desktop Electron GUI app
-
Go to the
guidirectorycd gui -
Install all the JavaScript dependencies by running:
npm install
-
Start the GUI in development mode by running:
npm run develop
If you change any javascript file while the development mode is running it will automatically transpile and reload the file so that the changes are visible almost immediately.
Please note that the GUI needs a running daemon to connect to in order to work. See Building and running mullvad-daemon for instruction on how to do that before starting the GUI.
Supported environment variables
MULLVAD_PATH- Allows changing the path to the folder with themullvad-problem-reporttool when running in development mode. Defaults to:<repo>/target/debug/.
Making a release
When making a real release there are a couple of steps to follow. <VERSION> here will denote the version of the app you are going to release. For example 2018.3-beta1 or 2018.4.
-
Follow the Install toolchains and dependencies steps if you have not already completed them.
-
Make sure the
CHANGELOG.mdis up to date and has all the changes present in this release. Also change the[Unreleased]header into[<VERSION>] - <DATE>and add a new[Unreleased]header at the top. Push this, get it reviewed and merged. -
Run
./prepare_release.sh <VERSION>. This will do the following for you:- Check if your repository is in a sane state and the given version has the correct format
- Update
package.jsonwith the new version and commit that - Add a signed tag to the current commit with the release version in it
Please verify that the script did the right thing before you push the commit and tag it created.
-
When building for Windows or macOS, the following environment variables must be set:
-
CSC_LINK- The path to the certificate used for code signing.- Windows: A
.pfxcertificate. - macOS: A
.p12certificate file with the Apple application signing keys. This file must contain both the "Developer ID Application" and the "Developer ID Installer" certificates + private keys.
- Windows: A
-
CSC_KEY_PASSWORD- The password to the file given inCSC_LINK. If this is not set thenbuild.shwill prompt you for it. If you set it yourself, make sure to define it in such a way that it's not stored in your bash history:export HISTCONTROL=ignorespace export CSC_KEY_PASSWORD='my secret'
-
macOS only:
-
NOTARIZE_APPLE_ID- The AppleId to use when notarizing the app. Only needed on release builds -
NOTARIZE_APPLE_ID_PASSWORD- The AppleId password for the account inNOTARIZE_APPLE_ID. Don't use the real AppleId password! Instead create an app specific password and add that to your keyring. See this documentation: https://github.com/electron/electron-notarize#safety-when-using-appleidpasswordSummary:
- Generate app specific password on Apple's AppleId management portal.
- Run
security add-generic-password -a "<apple_id>" -w <app_specific_password> -s "something_something" - Set
NOTARIZE_APPLE_ID_PASSWORD="@keychain:something_something".
-
-
-
Run
./build.shon each computer/platform where you want to create a release artifact. This will do the following for you:- Update
relays.jsonwith the latest relays - Compile and package the app into a distributable artifact for your platform.
Please pay attention to the output at the end of the script and make sure the version it says it built matches what you want to release.
- Update
Running Integration Tests
The integration tests are located in the mullvad-tests crate. It uses a mock OpenVPN binary to test the mullvad-daemon. To run the tests, the mullvad-daemon binary must be built first. Afterwards, the tests should be executed with the integration-tests feature enabled. To simplify this procedure, the integration-tests.sh script can be used to run all integration tests.

Mullvad Daemon
The daemon is implemented in Rust and is implemented in several crates. The main, or top level, crate that builds the final daemon binary is mullvad-daemon which then depend on the others.
In general one can look at the daemon as split into two parts, the crates starting with talpid and the crates starting with mullvad. The talpid crates are supposed to be completely unrelated to Mullvad specific things. A talpid crate is not allowed to know anything about the API through which the daemon fetch Mullvad account details or download VPN server lists for example. The talpid components should be viewed as a generic VPN client with extra privacy and anonymity preserving features. The crates having mullvad in their name on the other hand make use of the talpid components to build a secure and Mullvad specific VPN client.
- Cargo.toml - Main Rust workspace definition. See this file for which folders here are daemon Rust crates.
- mullvad-daemon/ - Main Rust crate building the daemon binary.
- talpid-core/ - Main crate of the VPN client implementation itself. Completely Mullvad agnostic privacy preserving VPN client library.
