Highlight any CPU name on a webpage, right-click, and instantly see benchmark data from PassMark and UserBenchmark in a clean overlay.

Installation

Usage

Highlight a CPU name (e.g. "Intel Core i5-13500") anywhere in your browser, right-click, and select Lookup CPU Information.

A styled overlay will appear with PassMark and UserBenchmark data. Click outside or press Escape to dismiss.

Matching is case-insensitive and supports partial names (e.g. "i5-13500" or "Ryzen 7 5800X").

uv run python cpu_userbenchmark_scrape.py     # UserBenchmark

Data is written directly into extension/.
