Watchman
A lightweight, Open Source Network Monitor for Windows & Mac
Watchman shows which apps are using your internet, even when they run quietly in the background. It also tracks live download and upload speed, CPU and RAM usage, traffic history, connection health, M-Lab speed tests, CSV export, and a compact taskbar widget. Local-first, no account required.
Hey Product Hunt, I built Watchman because I kept running into the same problem on my own PC: I could see that my internet or system was slow, but I didn’t know what was happening in the background.
Sometimes an app was using bandwidth quietly. Sometimes Windows felt slow and I wanted to know whether it was my CPU, RAM, network, or some background process. I wanted one simple place to answer: what is using my data, what is running, and what is affecting my PC right now?
So I built Watchman: a local-first Windows app that shows per-app network activity, live download/upload speed, traffic history, CPU and RAM usage, connection health, speed tests, CSV export, and a compact taskbar widget.
- Is the app activity view useful? - Is the taskbar widget helpful? - What would you want me to improve next?
Love that it's local-first with no account required, finally a network monitor that respects privacy. The compact taskbar widget is a really thoughtful touch for keeping an eye on things without clutter.
does it actually show the process names behind each connection or just aggregate traffic per app? that detail usually makes or breaks these tools for me.
Does the M-Lab speed test run on a schedule or only when I click it, and is there any limit on how often you can hit their servers?
Finally something that explains why my fan kicks on when I haven't touched anything. The per-app traffic breakdown is genuinely useful, and I love that it just runs locally without an account.
