Wisp VPN is a free, open source VPN client for Windows built on WireGuard. It is aimed mainly at users in Russia and neighboring countries who face slow or blocked access to services like YouTube, Telegram, Discord, and various foreign content delivery networks, due to provider throttling and deep packet inspection that can detect standard VPN protocols. The project's goal is a client that needs no account, no card details, and no subscription: just download it, run it, and connect. The project is written in C# using the .NET platform and follows an MVVM structure with three main screens, one for connecting, one for choosing a server, and one for settings. Under the hood it already includes a parser for WireGuard configuration files, a tool for measuring ping to different servers, key generation using X25519 cryptography, and a kill switch that blocks network traffic if the VPN connection drops. The plan is to keep the service completely free with no traffic limits and no logging of user activity, and 48 servers across Europe, the Americas, and Asia are listed as available choices. As of this README, the project is still in active development. While pieces like the configuration parser and ping measurement already work, the actual WireGuard tunnel connection is not yet functional, so pressing the connect button in a build from source currently returns a not yet implemented response. Only a Windows client is planned for now, with no other platforms currently on the roadmap. To try it, users can download a prebuilt installer from the project's website, or build it from source themselves using the .NET 8 SDK with the Windows Desktop workload installed. The code is entirely open for anyone to review, and the project states its aim is to avoid writing custom cryptography and instead rely on established libraries for WireGuard and X25519. It is licensed under MIT and is not affiliated with any commercial VPN service.
