Five seconds of bad internet is easy to notice and hard to explain. netprobe keeps a small local record of your connection so you can see whether the problem was your router, your ISP, or the service you were using.
Press Start and leave it running. The default setup checks your home router plus public endpoints from Cloudflare, Google, and Quad9. If the connection stutters, the chart and incident view keep the useful context.
The dashboard shows current latency, failures, and the route used for each target.
Related failures are grouped into likely incidents. A quiet incident view is a good result.
The default configuration is ready to run on most home networks.
Building the app requires Xcode and Go 1.24 or newer:
./scripts/build-macos-app.sh
open dist/Netprobe.app
On the first launch:
- Open Configuration and choose Install Defaults.
- Choose Save and Validate.
- Press Start.
Most home routers use 192.168.1.1. Change that address if yours does not. The three public targets are ready to use.
The time menu changes how much history is visible. It does not stop collection. Pressing Start begins a clean dashboard view; earlier results stay available for reports.
The same collector also runs from a terminal on macOS, Linux, and Windows. See the CLI and configuration guide, advanced usage, release guide, or contributor guide when you need more than the basic app.
