Why they exist
UPBOOST tunes PCs by hand, live, with a technician. A good share of what people treat as a hardware limit is configuration — a 144 Hz monitor delivering 60, a 1000 Hz mouse stuck at 125, the Windows power plan holding the CPU back. These tools help you see that before spending money on parts.
Each one also says where its result stops being valid. Browser measurements have a margin of error, and a tool that hides it gives you a pretty, wrong number. If you would rather understand the service first, the method page shows layer by layer what the technician tunes.
