What it does

ClumsyNetWatch is built for homelabbers, sysadmins, small IT teams, and MSPs who need fast local network visibility without dragging in a full monitoring stack. Run one scan across multiple subnets, review live hosts and open ports, inspect TLS and security findings, launch SSH or RDP workflows faster, and compare snapshots later to see exactly what changed. No cloud. No subscription. No agent deployment.

Who it's for

Homelabbers
Know exactly what's on your network and what's listening.
Sysadmins
Fast inventory and change tracking without enterprise tooling overhead.
Small IT teams
Network audits and security checks without NMS budget or complexity.
MSPs
Periodic network reviews for managed clients. Commercial license required.

Features

🌐

Multiple Subnet Scanning

Scan comma-separated subnets, ranges, or single IPs in one run. Overlapping targets are deduplicated automatically.

🔍

Deep Host Discovery

Ping sweep + hostname resolution via DNS, mDNS, LLMNR, and NetBIOS. Every device found.

🏷️

Offline Vendor Lookup

Full IEEE MAC address database embedded inside the exe. No internet required, ever.

🖥️

Per-Device SSH & RDP Launch

Save host-specific SSH and RDP credentials, launch sessions from the context menu, and skip repetitive login typing.

📊

Network Statistics Panel

Open a post-scan stats window with host counts, top vendors, device types, top ports, and a security overview.

📤

Export Reports

Export as CSV, branded HTML report, or JSON. Import previous JSON scans back into history.

🔐

Custom Credential Manager

Add your own username/password pairs to extend default credential checks. Usernames stay visible, passwords stay masked.

💡

Wake-on-LAN

Send magic packets to wake sleeping hosts directly from the right-click context menu.

🌙

Dark / Light Theme

Auto-detects your Windows system theme. Switch anytime with the theme toggle.

🛡️

Security Risk Flags

Automatic per-host analysis highlights weak services, cert issues, SNMP defaults, and accepted default credentials — with passwords always masked in the UI.

🏷️

Device Labels & Notes

Right-click any host to set a friendly name (NAS, Dad's PC, Smart TV) and free-text notes. Persisted across sessions and searchable in the filter bar.

⚙️

Preferences & Auto-Rescan

Configure minimize-to-tray, startup behaviour, balloon notification threshold, and auto-rescan intervals (5 / 15 / 30 min) — all saved to disk.

🔔

Background Monitoring

Minimize to the system tray and receive Windows balloon notifications whenever new devices join or known devices disappear from your network.

Release Candidate 1 · Pre-launch

ClumsyNetWatch has reached v0.9.0 Release Candidate 1. The product is substantially hardened, but public download is still locked pending LLC registration confirmation and signed binary publication — this is a legal and administrative hold, not a technical one. Check the downloads page for current status.

Only use ClumsyNetWatch on networks you own or have explicit authorization to assess. This is a reconnaissance tool, not an exploitation framework. Unauthorized network scanning is illegal and a violation of the Terms of Use.

ClumsyNetWatch runs entirely on your machine. Scan results never leave your device. No account required. No ads. Telemetry is opt-in via a first-run consent dialog and can be disabled at any time in Preferences. See the Privacy Policy for full detail.
