# Mullvad VPN — Open Source Privacy-First VPN Client > A free, open-source VPN client supporting WireGuard and OpenVPN with a strong focus on privacy, built in Rust with native apps for all major platforms. ## Install Save as a script file and run: # Mullvad VPN — Open Source Privacy-First VPN Client ## Quick Use ```bash # Install on Linux via the official repository # Debian/Ubuntu: sudo apt install mullvad-vpn # Or download from the GitHub releases page mullvad account login YOUR_ACCOUNT_NUMBER mullvad connect ``` ## Introduction Mullvad VPN is a fully open-source VPN client application built in Rust. It connects to the Mullvad VPN service with a strong emphasis on privacy: no email, no phone number, and no personal data required to create an account — just a randomly generated account number. ## What Mullvad VPN Does - Provides encrypted VPN tunnels using WireGuard or OpenVPN protocols - Runs native desktop apps for Linux, macOS, and Windows built with Rust and Electron - Includes a mobile app for Android and iOS - Features a kill switch that blocks all traffic if the VPN connection drops - Supports multihop routing through two VPN servers for additional privacy ## Architecture Overview The client is split into a Rust daemon (mullvad-daemon) that manages tunnel connections and firewall rules, and a frontend GUI built with Electron (desktop) or native code (mobile). The daemon handles protocol negotiation, DNS leak protection, and the kill switch via OS-level firewall rules (nftables on Linux, PF on macOS, WFP on Windows). All cryptographic operations use the WireGuard or OpenVPN libraries. ## Self-Hosting & Configuration - Download official packages for Linux (deb/rpm), macOS, or Windows from GitHub releases - The CLI tool mullvad provides full control over connections, servers, and settings - Configure DNS to use Mullvad's ad-blocking DNS or custom resolvers - Split tunneling allows specific apps to bypass the VPN on supported platforms - All settings persist across reboots via the daemon's configuration store ## Key Features - Fully open-source client and infrastructure code - WireGuard and OpenVPN support with automatic protocol selection - Kill switch and DNS leak protection enabled by default - No-logging policy with independent security audits published publicly - Anonymous accounts — no email, name, or personal data required ## Comparison with Similar Tools - **WireGuard CLI** — raw protocol client; Mullvad adds server management, kill switch, and GUI - **OpenVPN** — generic VPN protocol; Mullvad wraps it with privacy-focused defaults - **Tailscale** — mesh networking tool; Mullvad is a traditional VPN for internet privacy - **ProtonVPN** — similar privacy focus but closed-source client; Mullvad is fully open source - **Gluetun** — Docker VPN container; Mullvad is a desktop/mobile client with native UI ## FAQ **Q: Is the VPN service itself free?** A: No. The client is open source and free, but the VPN service requires a paid subscription. This listing covers the open-source client software. **Q: Can I use the client with other VPN providers?** A: The client is designed for the Mullvad service. For generic WireGuard connections, use the WireGuard CLI. **Q: Does it support split tunneling?** A: Yes, on Linux, Windows, and Android. You can exclude specific apps from the VPN tunnel. **Q: Has the code been audited?** A: Yes. Multiple independent security audits have been conducted and the reports are publicly available on Mullvad's website. ## Sources - https://github.com/mullvad/mullvadvpn-app - https://mullvad.net --- Source: https://tokrepo.com/en/workflows/asset-44ade926 Author: Script Depot
