OpenSpeedTest-Server

What is OpenSpeedTest-Server?

OpenSpeedTest-Server is a macOS network testing utility for running a local speed test server on your Mac. It helps home users, IT staff, and anyone troubleshooting slow Wi‑Fi or Ethernet connections measure transfer speeds between devices on the same network using a web browser. After launching the app on one device, you open the shown address from another device to test download and upload performance across your local network. This makes it useful for checking router placement, comparing wired and wireless performance, validating home lab changes, or testing office network links. The app is part of the OpenSpeedTest product family from Openspeedtest and is also available on other platforms for similar local network testing workflows.

Key features

• Host a local network speed test server on your Mac
• Test download and upload speed from another device in a web browser
• Measure Wi‑Fi and Ethernet performance within your local network
• Compare connection quality between different rooms, devices, or router setups
• Use it for home labs, office troubleshooting, and local network checks

Safety overview

Status: Safe

This app’s network activity is normal for its purpose because it temporarily serves a local speed test page to other devices on your network. It may expose a local address that other devices on the same network can open while the server is running, so use it on networks you trust and quit the app when you are finished testing. Removing it only affects your ability to run these local network tests from the Mac.

Recommendation: Keep OpenSpeedTest-Server if you use your Mac to test Wi‑Fi, Ethernet, home lab, or office network performance. If you no longer run local speed tests, you can remove it without affecting macOS beyond losing that testing tool.
