Shopify Competitor Price Tracker: Prices, Stock and Launch Alerts

See every move your competitors make on their Shopify stores, and what to do about it. Add competitor store domains and schedule a daily run. You get every price cut, price increase, new discount, sellout, restock, launch, and removed product, plus a short competitor brief with one suggested action.

Price monitoring apps charge $99 a month and up. This runs on your own schedule and you pay only for what it finds.

What you get

One row per change:

• Change type: price-decrease, price-increase, sale-started, sale-ended, new-product, removed-product, sold-out, restocked
• Product name, type, and link
• Old price, new price, and the percent change

One row per store:

• A plain-English brief of what the competitor did, with numbers and product names
• One suggested action for this week, written for your store when you describe it
• Catalog stats: product count, products on sale, sold-out products, median, lowest, and highest price

How to track competitor prices on Shopify

1. Add competitor domains under Competitor stores, one per line.
2. Optional: describe your own store in one line, so the brief is written for you.
3. Run it once. The first run saves each catalog as a baseline.
4. Schedule it daily. Every later run reports what changed since the last one.
5. Optional: add a webhook to send briefs to Slack, Zapier, Make, or n8n.

Pricing

Event	Price
Store checked (catalog read successfully)	$0.01
Change detected	$0.02
AI competitor brief (only when the store changed)	$0.25

Ten stores checked daily costs about $3 a month before changes. Stores that hide their product feed are never charged.

Good to know

• The Actor reads each store's public product feed. It does not log in, add to cart, or touch checkout.
• Stock is reported as available or sold out. Shopify does not publish exact inventory counts publicly, so we never estimate them.
• A few stores turn off their public product feed. Those are reported as not-shopify and cost nothing.
• Snapshots live in a named key-value store in your own account (catalog-watch-state by default).

FAQ

How do I track a competitor's Shopify prices?

Add the competitor store domains, click Start once to save a baseline, then schedule a daily run. Each run reports every price increase, price decrease, sale, sellout, restock, new product and removed product since the last check.

How does it read a Shopify store?

It reads the store's public products.json feed. No login, no API key and no access to the store's admin.

Does it work with every Shopify store?

Most stores work. Stores that hide their product feed are reported as not-shopify and are not charged.

Can I watch only certain products?

Yes. Use Only products matching to report changes for one keyword, such as runner, or pick only the change types you care about.

Can I get the competitor brief in Slack?

Yes. Add a webhook URL and each store brief is POSTed as JSON when anything changed. Connect it to a Slack workflow, Zapier, Make or n8n.
