our call
Start with Asinseed — highest vibe code, weakest moat.
Asinseed
Asinseed's frontend table views and keyword filtering options are trivial to build using Cursor or Claude in a few days. However, the product relies entirely on pre-indexed Amazon search volume data, rank tracking histories, and reverse ASIN mappings across millions of products. Rebuilding this data layer without paying steep third-party API fees or managing complex scraper farms is non-viable.
you can rebuild
- ASIN keyword search bar and results data grid
- Keyword filtering by search volume, word count, and position
- CSV and XLSX data export tools
- Keyword list aggregation and tagging system
- Basic search volume visualization charts
what you lose
- Proprietary historical Amazon keyword search volume estimates
- Pre-computed reverse ASIN index covering millions of SKUs
- Managed residential proxy network for continuous Amazon scraping
- Automated detection of search volume seasonal trends
- Zero-maintenance data freshness and schema updates for Amazon SERPs

MerchantWords
Building the UI and keyword search dashboard takes a weekend, but replicating MerchantWords' multi-year database of billions of Amazon buyer search queries is impossible via pure code generation. The value lies entirely in historical search volume datasets and proprietary reverse-ASIN indexing.
