our call
Start with Feedonomics — highest vibe code, weakest moat.
AMZScout
Building the Chrome extension UI and FBA profit calculator takes a few days with AI assistance. However, AMZScout relies on continuous scraping of millions of Amazon ASINs and historical BSR metrics to estimate sales volume. You cannot easily replicate their underlying data infrastructure without massive proxy budgets or third-party data providers.

- Search volume trend estimates derived from aggregated shopper data
real moats
- Multi-terabyte historical Amazon catalog and BSR database
- Resilient distributed scraping infrastructure and proxy management
- Calibrated machine learning models translating BSR velocity to unit sales
