StoreSentry watches the Shopify stores you compete with and tells you when something actually changes: price drops and hikes, new product launches, items selling out or coming back in stock.
No dashboards to babysit and no pixel-diff false alarms โ StoreSentry reads structured catalog data, so every alert is real. You get one clean digest by email or Telegram: daily, weekly, or instant.
What it tracks:
Built for small stores watching 1โ15 competitors, not enterprise pricing teams. Set up in two minutes: paste a competitor's store URL and you're done.
Free plan: watch 1 competitor forever. Paid plans from $19/mo with a 14-day free trial. WooCommerce support is next on the roadmap.
