Scroll Test is a free, static, in-browser diagnostic. There are no accounts, no fees, and no servers receiving your input.

What the tool is

• A screening aid that reports browser-observed wheel events in plain language.
• Not a repair service, not a warranty verdict, and not professional advice.
• Results describe one timed sample of delivered events; they confirm no hardware condition and no repair.
