NetPulse
NetPulse is a real-time internet speed tester built with Flask, WebSocket, and SSE — measure your download, upload, and ping instantly
Know your speed. Own your connection
NetPulse is a free browser-based internet speed tester. It connects to the nearest server and runs a live test to show how fast your internet connection really is — including download, upload, and ping.
How does it work?
- Click "Start Test" — NetPulse finds the best server near you automatically.
- Ping is measured first — this shows your connection response time in milliseconds.
- Download speed is tested — how fast data travels from the server to your device.
- Upload speed is tested — how fast your device sends data to the server.
- Results are saved — your last 10 tests are stored so you can track your speed over time.
What the Results Mean
- Download Speed: How fast you receive data. Affects streaming, browsing, and downloads. Higher is better.
- Upload Speed: How fast you send data. Affects video calls, cloud uploads, and online gaming. Higher is better.
- Ping: The delay between your device and the server in milliseconds. Lower is better. Under 20ms is excellent for gaming and video calls.
