NitroNet turns the eternal question - "is it my internet?" - into a clear answer in seconds. It's a fast, all-in-one network toolkit that shows you exactly what your connection is doing: speed, devices, latency, and more, in a clean window anyone can read at a glance.
No command line, no sign-up, no cloud. Open it and you instantly see your live upload and download, what's connected to your network, and how healthy your connection really is - all running right on your own computer.
Highlights
- Live traffic at a glance - watch real-time upload and download with average and peak, so you can instantly spot what's hogging your bandwidth.
- One-click speed test - measure your true download and upload speeds with live progress, no sketchy websites required.
- See every device on your network - scan your Wi-Fi or LAN to discover what's connected, by IP and hardware - handy for spotting strangers or just taking stock.
- Test if it's up - and how fast - ping any host over ICMP, TCP, UDP, or QUIC to check reachability and latency the way that actually matters for your app or game.
- Trace the whole path - traceroute reveals every hop between you and a server, with timing for each - perfect for pinning down exactly where things slow down.
- Check for open doors - scan ports (common, top 1000, or your own list) to see which services are exposed on a device.
- Know what's talking to the internet - view active connections and the exact app behind each one.
- Your network, decoded - interfaces, IP addresses, gateways, and routes laid out plainly, plus your public IP with provider and country.
- Private by design - everything works offline and stays on your device. No account, ever.
- Works everywhere - native apps for macOS, Windows, and Linux.
How it works
Launch NitroNet and the dashboard greets you with a live snapshot of your connection - active interfaces, real-time traffic, and your public IP. From there, the sidebar gives you a tool for every question: run a speed test, scan for devices, ping a server, trace a route, or check open ports - each one a click away, with results in plain language.
Want it keeping watch while you work? NitroNet tucks into your menu bar or tray and quietly keeps an eye on things in the background. No setup, no account - it just runs.
Perfect for
- Anyone with flaky Wi-Fi - figure out whether it's your connection, your router, or the website - in seconds.
- Gamers, streamers & remote workers - keep an eye on latency and bandwidth where every millisecond counts.
- Home network owners - see exactly who and what is connected, and spot anything that shouldn't be there.
- Developers, IT folks & the curious - a full diagnostic kit (ping, traceroute, port and host scan, sockets) without juggling a dozen command-line tools.
