To inspect a computer, you may want details about its firmware, operating system, or installed software, and tools differ in how they provide access to that information. Compared on firmware details, installed software, and operating systems, the entries help you see what information is listed. A command-line interface and portable version may also matter to how you work, while report export is relevant if you need to share results. BelManage, HWMonitor, and Fastfetch are options to compare. Review free-plan availability and paid-from pricing too, then weigh the listed information and access features against the systems you need to inspect.

35 system information software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
