our call

Start with ZIK Analytics — highest vibe code, weakest moat.

Keepa

Building a script to scrape 50 Amazon pages today is simple. Replicating Keepa requires continuous, anti-bot-resistant scraping across 3+ billion SKUs along with years of immutable historical price and BSR history that cannot be backfilled.

you can rebuild

  • Targeted ASIN price monitoring for a narrow list of SKUs
  • Webhooks and email alerts for custom price-drop thresholds
  • Simple charting UI for tracked product price movements
  • Basic Buy Box price tracking for custom product lists
  • CSV export of internal, self-scraped pricing history

what you lose

  • Multi-year historical dataset of price, BSR, and offer count across 3+ billion SKUs
  • Infrastructure handling massive proxy rotation and Amazon CAPTCHA/WAF bypasses
  • Sub-second cached API responses for arbitrary Amazon products globally
  • Native integration into major third-party Amazon seller repricers and sourcing tools
  • Browser extension displaying embedded inline charts on Amazon product pages

real moats

  • Unbackfillable historical database spanning multi-year pricing and rank trends
  • Capital-intensive residential proxy and headless browser infrastructure engineered specifically for Amazon WAFs
  • Deep ecosystem lock-in as the standard backend data supplier for Amazon merchant software

ZIK Analytics

Building the UI for sales volume estimation and keyword research takes less than a week. However, ZIK Analytics relies on parsing live marketplace data at scale while bypassing aggressive anti-bot protections (Akamai, Cloudflare, eBay bot detection). You are not paying for code; you are paying for residential proxy bandwidth and anti-scraping maintenance.

you can rebuild

  • Keyword research and title optimization builder
  • Competitor watchlist tracking dashboard
  • Sell-through rate and average price calculators
  • Product profit margin calculator
  • Category top-seller ranking charts

what you lose

  • Pre-indexed historical sales data across millions of marketplace SKUs
  • Managed residential proxy rotation and anti-bot evasion infrastructure
  • Automated bulk competitor monitoring pipelines across thousands of stores
  • Continuous scraper maintenance when eBay or Amazon updates HTML layouts
  • Direct product source matching between suppliers like AliExpress and eBay
