Ordinary Mac or Windows computers you probably already own — testPod does not force you to buy new machines. What matters is that they meet the minimum specs, because a busy testing bench on very old PCs or a weak wifi network is the main cause of instability.
We publish exact minimum and recommended specs — CPU, RAM, storage, network speed, plus the USB hubs, cables, and label printers we recommend — on the hardware requirements page. Check it before you start.
