Know the moment a competitor undercuts you.

Competitor Price & Stock Watch tracks your competitors' product pages and alerts you the instant they drop a price, change stock, or sell out — so you never lose a sale to an undercut you didn't see coming. We're building it now. Join the waitlist for early access.

Runs on your machine Undercuts $99+/mo tools Alerts the moment it matters

Your competitors change prices while you're not looking.

A competitor quietly drops their price on your best seller and you don't find out until sales dip. One of their products goes out of stock — a selling opportunity — and you miss the window. Checking their stores by hand doesn't scale, and the tools that do it for you start at $99/month and are built for enterprise catalogs, not a webshop watching a handful of rivals.

Watch. Compare. Get alerted.

01 · watch

Add competitor URLs

Point the script at the competitor product pages you care about and match them to your own products.

02 · extract

Read price & stock

On a schedule you set, it fetches each page and pulls the current price, currency, and availability.

03 · compare

Diff against you

It compares every reading against the last snapshot and against your own price for the matched product.

04 · alert

Get notified

When something that matters changes, you get an alert — with the old price, the new price, and the delta.

The signals that actually move revenue.

Undercut

A competitor's price drops below yours on a matched product — the alert you can't afford to miss.

Price change

Any move up or down, with the old price, new price, and percentage delta so you can react fast.

Out of stock

A competitor sells out — a selling opportunity to capture demand while they can't fulfil it.

Restock

They're back in stock and competing again — know the moment the pressure returns.

Price history

A local log of every reading over time, so you can see how a competitor prices and export it.

You set the cadence

Check as often or as rarely as you like. Polite by default — sane delays, never hammering a store.

Enterprise-grade watching, without the enterprise bill.

Runs on your machine

No hosted scraping infrastructure to pay for. Checks come from your own connection — often an edge over cloud scrapers that get bot-walled.

A fraction of the price

Because there's no server side to run, we undercut the $99+/month incumbents. Pay for the watching you need, nothing more.

Local-first & private

Q/01 When does Competitor Price & Stock Watch launch?
We're building it right now. Join the waitlist and you'll be among the first to get access when it ships — and you'll help shape what it does before then.
Q/02 Which stores and platforms will it support?
v1 focuses on independent Shopify, WooCommerce, and Magento stores — the realistic competitor set for most webshops. Marketplace giants like Amazon and bol.com are on the roadmap for later.
Q/03 How much will it cost?
A fraction of the $99+/month enterprise price-monitoring tools. Final pricing is not set yet — the waitlist helps us get it right. Cereal itself is free to download.
Q/04 Can I suggest a store or marketplace to monitor?
Yes — there is an optional field in the waitlist form for exactly that. Tell us which webshop or marketplace you want monitored and it feeds directly into what we build.
Q/05 Where does the monitoring run?
On your own machine, like every Cereal script. Nothing runs on our servers, your data never leaves your device, and checks come from your own connection — which is often an advantage over cloud scrapers that get bot-walled.

Stop losing sales to undercuts you didn't see.
