Helium 10 is a large suite of Amazon seller tools: product research (Black Box), keyword research (Cerebro, Magnet), listing optimisation, profit analytics and alerts. The entry-level Starter plan was discontinued, so it now makes most sense for sellers with real volume.
Keepa tracks Amazon price and sales rank history for millions of products and displays charts right on Amazon product pages. Arbitrage sellers use it to see whether a price is stable, how often the item sells, and whether Amazon itself is on the listing.
Retail and online arbitrage on Amazon live and die by data: sales rank, price history, Buy Box competition, fees and ungating restrictions. These tools range from free browser extensions to full research suites. Beginners usually start with one scanner app plus Keepa, and add a sourcing suite once they are consistently profitable. The deciding factors usually come down to each tool's standout strength (for Helium 10: very broad feature set; for Keepa: essential price and rank history) weighed against its main drawback (entry price now $99-$129/mo versus steep learning curve).
