What should you sell? Find out from real sales

Type a category — kitchen, pets, camping — and Soldnova breaks it into real product types ranked by market gap: the ones that sell a lot while few sellers compete for them. No made-up lists: the signal is what actually sold on eBay.

How it works

• You give a seed (a category, or just an idea).
• We pull the product types people actually buy inside it.
• We rank them by estimated sales per active listing — that ratio is the gap.
• The free plan shows the top 3; Pro unlocks the full ranking and CSV export.

Why this signal

A product with lots of sales but thousands of sellers is not an opportunity, it is a fight. One with no sales is not a niche, it is a desert. Only the ratio between the two tells them apart — and we compute it from official eBay data (estimated sales, not exact counts).
