Before you switch

Networking and home-server software rewards patience. Read the hardware compatibility list before you buy or repurpose a device, and start with a spare machine or virtual machine. The communities around these projects are famously helpful — when something doesn’t work, someone has usually documented the fix.

Like every project on OpenShelf, OpenSpeedTest is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
