base on Cross-platform open source VPN client built in Rust, with mixnet anonymity and WireGuard speed. Protects metadata, not just IP addresses. Zero-knowledge payments for unlinkable online activities. <div align="center"> <img src=".github/assets/header.png" width="600"/> Open-source, cross-platform VPN client built with Rust that provides true privacy through decentralized mixnet technology and multi-hop censorship-resistant WireGuard tunneling. </div> # 🚀 What is NymVPN NymVPN is a privacy-focused, decentralized VPN application that goes beyond traditional VPNs by leveraging: - 🔀 [Mixnet](https://nym.com/mixnet) Technology: Anonymous 5-hop routing through Nym's decentralized network - ⚡ WireGuard + AmneziaWG: Fast, secure tunneling with built-in censorship resistance - 🛡️ Metadata Protection: Unlike traditional VPNs, protects both content AND traffic patterns (in mixnet mode) - 🔐 Zero-Knowledge Credentials: Private authentication using zero-knowledge [zk-nyms](https://nym.com/zk-nyms) - 🌍 No Single Point of Failure: Fully decentralized infrastructure <div align="left"> <img src=".github/assets/app.png" width="800"/> </div> <br /> <br /> <div align="left"> [<img height="40" width="120" src=".github/assets/apk-download-badge-1745835177551.png">](https://github.com/nymtech/nym-vpn-client/releases?q=android&expanded=true) [<img height="40" width="120" src=".github/assets/fdroid-badge.png">](https://f-droid.org/packages/net.nymtech.nymvpn/) [<img height="40" width="120" src=".github/assets/flathub-store.svg">](https://flathub.org/apps/net.nymtech.NymVPN) [<img height="40" width="120" src=".github/assets/play-badge.png">](https://play.google.com/store/apps/details?id=net.nymtech.nymvpn) [<img height="40" width="120" src=".github/assets/obtainium-badge.png">](https://apps.obtainium.imranr.dev/redirect?r=obtainium://app/%7B%22id%22%3A%22net.nymtech.nymvpn%22%2C%22url%22%3A%22https%3A%2F%2Fgithub.com%2Fnymtech%2Fnym-vpn-client%22%2C%22author%22%3A%22nymtech%22%2C%22name%22%3A%22NymVPN%22%2C%22preferredApkIndex%22%3A0%2C%22additionalSettings%22%3A%22%7B%5C%22includePrereleases%5C%22%3Afalse%2C%5C%22fallbackToOlderReleases%5C%22%3Atrue%2C%5C%22filterReleaseTitlesByRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22filterReleaseNotesByRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22verifyLatestTag%5C%22%3Afalse%2C%5C%22dontSortReleasesList%5C%22%3Afalse%2C%5C%22useLatestAssetDateAsReleaseDate%5C%22%3Afalse%2C%5C%22releaseTitleAsVersion%5C%22%3Afalse%2C%5C%22trackOnly%5C%22%3Afalse%2C%5C%22versionExtractionRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22matchGroupToUse%5C%22%3A%5C%22%5C%22%2C%5C%22versionDetection%5C%22%3Afalse%2C%5C%22releaseDateAsVersion%5C%22%3Afalse%2C%5C%22useVersionCodeAsOSVersion%5C%22%3Afalse%2C%5C%22apkFilterRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22invertAPKFilter%5C%22%3Afalse%2C%5C%22autoApkFilterByArch%5C%22%3Atrue%2C%5C%22appName%5C%22%3A%5C%22%5C%22%2C%5C%22shizukuPretendToBeGooglePlay%5C%22%3Afalse%2C%5C%22allowInsecure%5C%22%3Afalse%2C%5C%22exemptFromBackgroundUpdates%5C%22%3Afalse%2C%5C%22skipUpdateNotifications%5C%22%3Afalse%2C%5C%22about%5C%22%3A%5C%22%5C%22%2C%5C%22refreshBeforeDownload%5C%22%3Afalse%7D%22%2C%22overrideSource%22%3Anull%7D) [<img height="40" width="120" src=".github/assets/app-store-badge.svg">](https://apps.apple.com/app/id6471254143) [<img height="40" width="120" src=".github/assets/linux-badge.png">](https://github.com/nymtech/nym-vpn-client/releases?q=linux&expanded=true) [<img height="40" width="120" src=".github/assets/macos-badge.png">](https://github.com/nymtech/nym-vpn-client/releases?q=macos&expanded=true) [<img height="40" width="120" src=".github/assets/windows-badge.png">](https://github.com/nymtech/nym-vpn-client/releases?q=windows&expanded=true) </div> # ✨ Key Features 🎯 Dual-Mode Privacy Architecture -
