MarketFlow365 reads the full history of any Amazon listing — price, rank, offers, reviews — in a chart that doesn't make you squint. Built for every Amazon seller who actually needs the data.
Free tier · no credit card · all marketplaces
Toggle any of 36 historical series — Amazon, Buy Box, New, Used, Warehouse, FBA, sales rank, ratings, offer counts. Crosshair tooltip shows every visible value at any timestamp. No squinting.
Compose 50 filters into named, reusable searches. Every result card shows a sparkline so you read history before you click.
A single global toggle flips the entire app between focused and complete. Same data, same features — just the right amount of UI for the moment.
