Category Whitespace Finder for Manufacturers

Score product categories for whitespace using competition, review saturation, and demand gap analysis before adding inventory.

Deciding whether a category is worth manufacturing into usually comes down to gut feeling after browsing a few listings. This extension turns that browsing into a structured, weighted score — competition density, review saturation, and real qualitative signals like recurring complaints and price gaps. Features: Instant 0–100 whitespace score from listing count and average reviews Four weighted qualitative signals: complaints, price gaps, outdated listings, thin supply vs. demand A visual gauge showing exactly where a category lands A ranked pipeline of every category you've assessed, best opportunities first Pro: unlimited pipeline, CSV export Nothing connects to Amazon or any paid data source — you research the category yourself, and this structures your findings into a consistent, repeatable score.
