Ping-a-Ding-a-Ling

A real-time network latency monitor for diagnosing router problems, flaky connections, and other network gremlins. Useful for figuring out why your video calls drop or your games lag.

How it works

The app continuously pings a target (your router, a DNS server, whatever) and visualizes latency, jitter, and packet loss in real-time. It detects anomalies using statistical analysis and logs deviations so you can spot patterns.

Prerequisites

Node.js v18 or later.

Running

npx ping-a-ding-a-ling

This starts a local server and opens the UI in your browser. By default it runs on port 3001.

npx ping-a-ding-a-ling --port=8080    # use a different port
npx ping-a-ding-a-ling --no-browser   # don't auto-open browser

On Linux, auto-open requires xdg-utils. If it's not installed, use --no-browser and open http://localhost:3001 manually.

Data storage

Session history and ping data are stored locally in a SQLite database:

• macOS: ~/Library/Application Support/ping-a-ding-a-ling/
• Windows: %APPDATA%\ping-a-ding-a-ling\
• Linux: ~/.local/share/ping-a-ding-a-ling/

Uninstalling

To remove all traces of the app including your session data, delete the data directory listed above. If you installed globally, also run:

npm uninstall -g ping-a-ding-a-ling
