WinMTR 2.0

WinMTR 2.0 is a lightweight Windows network diagnostic tool that combines traceroute-style path discovery with continuous ping statistics.

This version adds a practical command-line experience similar to Linux mtr, per-hop ASN lookup, IPv4/IPv6 selection, and a native Windows GUI with system-following dark mode.

Features

• Live CLI mode by default when a target host is passed on the command line
• In-place terminal refresh with Ctrl+C stop support
• Optional bounded runs with cycle or duration limits
• Per-hop ASN lookup in CLI, copied text reports, and exported reports
• IPv4 and IPv6 selection with -4 and -6
• GUI mode for classic WinMTR usage
• Native Windows light/dark appearance for the GUI
• Text and HTML export support

Requirements

• Windows 7 or newer
• Visual Studio with C++ and MFC support for local builds
• A modern Windows SDK and C++ toolset

CLI Usage

WinMTR runs in CLI mode whenever you launch it from a terminal with a target host. Use --gui only when you explicitly want the desktop GUI.

WinMTR.exe google.com
WinMTR.exe bgp.tools -4
WinMTR.exe bgp.tools -6
WinMTR.exe --numeric example.com
WinMTR.exe --report-cycles 10 1.1.1.1
WinMTR.exe --report-seconds 30 --numeric example.com
WinMTR.exe --gui example.com

Supported options:

• -h, --help: show help
• -g, --gui: force GUI mode
• -r, --report: run in CLI live-report mode
• -c, --report-cycles <count>: stop after a fixed number of cycles
• -w, --report-seconds <seconds>: stop after a fixed duration
• -i, --interval <seconds>: set probe interval
• -s, --size <bytes>: set ICMP payload size
• -n, --numeric: disable reverse DNS lookups
• -4, --ipv4: force IPv4
• -6, --ipv6: force IPv6

GUI Usage

Launching WinMTR.exe without command-line arguments opens the GUI directly without showing a console window.

The GUI follows the Windows app light/dark setting where supported, including the main controls, status bar, and results table header.

Use this form if you want to open the GUI with a pre-filled target from a terminal:

WinMTR.exe --gui example.com

Build

Open src\WinMTR.sln in Visual Studio, or build from a Developer PowerShell:

MSBuild.exe src\WinMTR.sln /t:Build /p:Configuration=Release /p:Platform=x64

The release binary is written to:

src\Release_x64\WinMTR.exe

Automated Builds and Releases

• Pull requests targeting main build x64 and x86 ZIPs, available as workflow artifacts.
• Every push to main, including a merged pull request, builds both architectures and creates a separate GitHub release tagged main-build-<run number> at the exact commit built. Publishing runs only after both builds succeed. Re-running the same workflow run updates that run's release.
• Pushing a v* tag or publishing a release builds and attaches ZIPs to that versioned release.
• Running the workflow manually on a branch builds artifacts only; running it on a tag also publishes release assets.

CI uses the Windows Server 2022 runner with Visual Studio 2022 and the v143 toolset so the compiler and installed MFC libraries match.
