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.

Build

End-user requirements for the recommended standalone release:

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
