I used NetWorx, a very handy tool to measure your network Bandwidth.
It calculates how much bandwidth is being used by the computer in real-time. It can also tell you the possible problem if you are having and tells you if your Bandwidth limits exceeds. NetWorx version 6 was recently launched.
Apart from the new featureset, one thing that upset me was that Networx is no longer a freeware. It is available as a 30 day trial software. After the trial period, the user will need to purchase a license in order to keep using it.
So, what is the best alternative to Networx, or, what is the best Bandwidth & traffic monitoring tool for Windows currently?
Quick update for 2026 — the NetWorx combo (live graph + daily/monthly totals + quota alerts) is still alive, just under different names. Closest free replacements:
NetTraffic (venea.net) — nearest NetWorx clone. Live up/down chart, usage history, quota counter, installer or portable, freeware. Grab this first.
TrafficMonitor (GitHub: zhongyang219/TrafficMonitor) — free + open source, real-time up/down on the taskbar or a floating desktop widget. Actively maintained, very light. My default now.
BitMeter II (codebox.org.uk) — free, scrolling real-time graph + configurable alerts. BitMeter OS is the browser-based sibling for a headless box.
GlassWire Free — real-time per-app breakdown, clean UI; free tier just caps history depth.
Sniffnet (GitHub: GyulyVGC/sniffnet) — free/open-source, cross-platform, for live per-connection traffic rather than just totals.
