NetCut, from Arcai, is the tool most Windows users learn about when a housemate is streaming 4K on the shared connection and the router admin page will not load. It scans the local subnet, lists every device, and, with a click, ARP-spoofs a target off the network. That last part is what gets people looking for something else: NetCut needs an outdated WinPcap driver on modern Windows, prompts a full firewall permission dance on every launch, and the free tier now shows ads and gates the bandwidth cap behind a paid upgrade. Alternatives fall into two camps: proper network diagnostic tools that see what NetCut sees without the shady bits, and open-source ARP tools that do exactly what NetCut does, only cleaner. We compared seven and put the diagnostic-first ones ahead.

Why people leave NetCut
The complaints line up across forums, and every one of them has a cleaner tool built to fix it.
The WinPcap driver dance
NetCut still installs a legacy WinPcap or Npcap driver on setup, and Windows 10 and 11 both prompt for elevated permissions every time the app opens. Angry IP Scanner and Advanced IP Scanner do the same discovery job with none of that.
The free tier keeps shrinking
Ads on launch, a paid “Defender” upsell, and bandwidth-cap features now behind a paid tier. The open-source alternatives give the same features away.
Antivirus flags on every install
Because NetCut’s ARP-spoofing engine is functionally a network attack, most consumer antivirus products flag it as PUA or a Trojan on install. Diagnostic tools like Wireshark and GlassWire ship signed installers and clear vendor identities that antivirus recognizes.
Cutting a housemate off is a bad idea
ARP spoofing on a shared network is a blunt tool. It disrupts every session on the target device, sometimes takes the router down with it, and violates most acceptable-use policies. Bandwidth-shaping alternatives like GlassWire and NetLimiter solve the underlying problem (someone is using too much of the connection) without breaking anyone’s Zoom call.
The UI belongs to a different decade
NetCut’s interface has not changed meaningfully since the Windows 7 era. The current field of diagnostic tools looks and behaves like modern software.
The alternatives
Wireshark – Best for actually seeing what is on the wire
Wireshark is the tool network engineers reach for when the answer needs to be exact. It captures every packet on the interface, decodes hundreds of protocols, and shows conversations end to end. It is not a one-click “kick this device” tool; it is a way to answer “who is actually using the connection, on which port, to where.”
Where it falls short: The learning curve is steeper than any other pick. First-run capture on Windows still needs Npcap installed alongside it.
Pricing: Free. GPL v2. No paid tier exists.
Migrating from NetCut: Different tool for a different job. Install alongside a scanner like Angry IP Scanner when the goal is investigation rather than disruption.
Download: wireshark.org
Bottom line: The right pick when the question is “what is happening on my LAN,” not “how do I stop it.”
Angry IP Scanner – Best for a fast portable scan
Angry IP Scanner ships as a small Windows executable that runs without installing anything. Point it at a range, hit start, and it lists every reachable host with MAC address, hostname, and ping time within seconds. Cross-platform (Windows, macOS, Linux), portable, and fully scriptable through a plugin API.
Where it falls short: Discovery only. It will not throttle a device or block one.
Pricing: Free. GPL v2.
Migrating from NetCut: Direct replacement for NetCut’s scan-and-list feature. If cutting is not part of the plan, this is the whole tool.
Download: angryip.org
Bottom line: The fastest way to see what is on the LAN, with none of NetCut’s install prompts.
Advanced IP Scanner – Best zero-setup scan on Windows
Advanced IP Scanner is Windows-only, free, and installs in under a minute. It scans the subnet, resolves DNS names, and (its niche feature) offers a right-click “remote shutdown” or “remote RDP” hand-off for domain-joined machines. Popular with home lab users and small IT shops.
Where it falls short: Signed by Famatech, which sends anonymous usage stats unless opted out. Windows only.
Pricing: Free.
Migrating from NetCut: Same list-of-devices output, no ARP tricks. Replace NetCut’s scan panel with this.
Download: advanced-ip-scanner.com
Bottom line: The two-click Windows scanner most people should install first.
GlassWire – Best for watching the connection over time
GlassWire puts a real-time graph in the tray. Every process gets its own bandwidth line, alerts fire when a new app first touches the network or when traffic spikes past a threshold, and the built-in firewall lets you block outbound connections per process with two clicks. The paid tier adds remote monitoring; the free tier is enough for a home connection.
Where it falls short: The free tier limits history depth and remote monitors. Not a LAN-wide scanner; it watches the PC it runs on.
Pricing: Freemium. Free tier is generous. Paid starts at a modest subscription for the Basic tier.
Migrating from NetCut: Different angle: instead of finding and blocking a heavy user on the LAN, GlassWire tells you which app on your PC is consuming the most. When the problem is your own machine, this is the right diagnostic.
Download: glasswire.com
Bottom line: The tool to install when you want to know exactly what your PC is sending and receiving.
SoftPerfect WiFi Guard – Best for catching unknown devices
SoftPerfect WiFi Guard scans the LAN on a schedule and alerts on any new MAC address that appears. The whitelist of known devices is one click each. If someone connects to the network without you noticing, WiFi Guard is the tool that notices.
Where it falls short: Detection only. It will not eject the device; that is the router’s job.
Pricing: Free for personal use. Paid business tier is a modest one-time license.
Migrating from NetCut: Replaces NetCut’s “who is on my WiFi” checkbox with a proper alerting workflow.
Download: softperfect.com/products/wifiguard/
Bottom line: Set it up once, forget about it, and get an alert only when something changes.
NetLimiter – Best for capping bandwidth on your own PC
NetLimiter is a Windows-only traffic shaper that caps bandwidth per process on the machine it runs on. It doubles as a firewall with fine-grained outbound rules, and the priority system means Zoom traffic can be guaranteed while Steam downloads take the rest.
Where it falls short: Local-only, so it does not shape traffic for other devices on the LAN. Paid after a trial.
Pricing: Paid, with a functional trial. One-time license or subscription.
Migrating from NetCut: The right answer when the goal is “keep my own machine from saturating the connection,” which is usually the real problem.
Download: netlimiter.com
Bottom line: The professional traffic-shaping tool most Windows users actually needed instead of NetCut.
elmoCut – Best for a clean open-source NetCut clone
elmoCut is a Windows-only open-source ARP spoofer that does exactly what NetCut’s free tier does, without the ads, without the paid gates, and with a much cleaner UI. Built on Scapy and packaged as a single portable executable.
Where it falls short: ARP spoofing is a hostile action; consumer antivirus flags elmoCut just like NetCut. Use only on networks you own.
Pricing: Free. MIT.
Migrating from NetCut: Direct replacement, same workflow, none of the paywalls. Use responsibly and only on your own network.
Download: github.com/elmoiv/elmocut
Bottom line: The like-for-like NetCut swap when the goal is exactly the same feature set, done cleanly and openly.
How to choose
Pick Angry IP Scanner or Advanced IP Scanner if you just want to see what devices are on the network. Both replace NetCut’s scanner without any of the driver hassles.
Pick Wireshark when the question is “what is that device actually doing,” and you need packet-level answers.
Pick GlassWire or NetLimiter when the real problem is one PC saturating the connection, and you want to solve it by shaping traffic rather than kicking anyone off.
Pick SoftPerfect WiFi Guard if you want passive alerting whenever a new device joins the LAN.
Pick elmoCut only if you genuinely need the ARP-cut behavior on your own network, and want it in a cleaner open-source package.
Stay on NetCut only if you already paid for the Defender tier and the workflow is unchanged.
FAQ
Is NetCut safe to use?
The core scanner is safe, but the ARP-spoof feature is a hostile network action that most antivirus tools flag as a PUA. Running it on a network you do not own is against the acceptable-use policy of every ISP and most workplaces.
What is the best free NetCut alternative for Windows?
For scanning the LAN, Angry IP Scanner is the closest free replacement. For the ARP-cut feature specifically, elmoCut is the closest open-source clone.
Can I use Wireshark instead of NetCut?
Wireshark solves a different problem. Instead of finding and disconnecting devices, it shows exactly what traffic is on the network and where it is going. Install it when the goal is diagnosis; use a scanner when the goal is a device list.
Which NetCut alternative works on Windows 11?
Angry IP Scanner, Advanced IP Scanner, Wireshark, and GlassWire all support Windows 11 without a legacy driver install. NetCut still needs Npcap and a driver-permission prompt on every launch.
How do I limit a device’s bandwidth without cutting it off?
Do it at the router. Most consumer routers now have per-device QoS settings. On the local PC, NetLimiter shapes traffic per process without touching the LAN.
