Competitor Price & Stock Monitor (Shopify)

You're bookmarking competitor stores and checking them once a week. Their catalog is public JSON — a machine should be doing this.

Paste competitor Shopify store URLs, schedule the monitor (daily or hourly), and get one row per actual change: price drop, price increase, out of stock, back in stock, new product, removed product — with old/new price and % change. Straight to dataset, webhook, Google Sheets or n8n/Make.

Pricing that matches how monitoring works

Event	Cost

Detected change (any type)	$0.005

A typical 3-competitor watch generates 50–300 changes/month ≈ $0.25–$1.50/month. Incumbent monitoring tools charge $70+/month for the same signal.
