The main alternative: Helium 10

Helium 10 is the closest Amazon research tool in our records, but it is built for sellers of physical products, with keyword and product research, listing tools and ads tools. Authors usually don't need it.

What it costs: Platinum $99/mo billed yearly ($129 monthly), checked October 26, 2026
