Promising concept, but the core features don’t perform reliably.

CSS Peeper sounds great on paper, but in practice it struggles to deliver the basics you’d expect from an inspection tool.

Font detection is unreliable. Typography often isn’t recognized correctly, which forces me to switch to other tools just to confirm the actual font. That makes the workflow slower instead of easier.

Color extraction lacks practical output options. Colors do appear, but there’s no simple way to export them—no PDF, no image sheet, nothing that consolidates swatches with their hex values for quick reference or sharing.

Feature set feels incomplete for general users. Outside of the pure CSS‑viewing aspect, other extensions provide more accurate results and more usable export options. If someone needs dependable extraction of fonts, colors, or elements, this tool doesn’t quite get there.

Overall, the idea is solid, but the execution needs improvement before it can replace the alternatives that already handle these tasks more consistently.
