nPerf

What is nPerf?

nPerf is a network testing app for macOS that helps users evaluate the quality of their internet connection with more than a simple speed check. It is designed for home users, remote workers, gamers, and anyone troubleshooting fiber, cable, Wi‑Fi, or mobile hotspot performance on a Mac. The app can measure download and upload speed, latency, browsing responsiveness, and streaming quality to give a broader picture of real-world connection performance. It is commonly used to compare internet providers, diagnose slow connections, test local network conditions, or confirm whether a connection is performing as expected. nPerf is published by nPerf SAS and is also available on other platforms, making it useful for users who want consistent testing across devices.

Key features

• Measure download and upload speed
• Check latency and connection responsiveness
• Test web browsing performance
• Evaluate video streaming quality
• Compare real-world internet performance across test types
• Use a desktop app instead of running tests only in a browser

Safety overview

Status: Safe

nPerf is legitimate network testing software. Network access and collection of connection-performance data are consistent with its purpose, since the app must contact test servers to measure speed, latency, browsing, and streaming behavior. As with any internet testing tool, review its privacy details if you do not want diagnostic or usage data associated with your tests.

Recommendation: Keep nPerf if you use it to test internet speed or troubleshoot connection quality on your Mac. If you no longer use it, removing the app is usually low risk and mainly means you will lose quick access to its desktop testing tools.
