TunnelX is a free and open-source Windows split-tunneling client built by MaxFan. It routes selected apps, selected destinations, or the whole system through supported tunnel cores while keeping local and excluded destinations on the normal network path.

Status: pre-release. Review docs/PUBLISHING_CHECKLIST.md before publishing a public repository or release artifact.

Features

App-based split tunneling for selected Windows processes
Full-route mode for whole-system tunneling
Xray-core / sing-box based V2Ray workflows
Local SOCKS5 proxy for tools that need 127.0.0.1
DNS redirect, IPv6 blocking, leak guard, route diagnostics, and traffic history
Persian-first Windows desktop UI

Build

End-user requirements for the recommended standalone release:

Windows 10/11
64-bit Windows (win-x64). 32-bit Windows is not supported by the current release package.
Administrator privileges when running the app, because route and packet interception features need elevated access
No separate .NET Runtime installation is required for the self-contained standalone EXE.

Developer requirements for building from source:

.NET 8 SDK

dotnet build AppTunnel.sln -c Release
dotnet publish AppTunnel\AppTunnel.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:EnableCompressionInSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:DebugType=None -p:DebugSymbols=false

More release notes are in docs/BUILD.md. Future ideas are tracked in docs/ROADMAP.md.
