What can I monitor with WebMonitor.fyi?

You can analyze website content for specific information like prices, product availability, job listings, news articles, event updates, competitor websites, and other web content using natural language queries.

How does the AI-powered monitoring work?

Our AI understands website content like a human would, detecting meaningful changes in prices, stock levels, content updates, and more. You can set natural language monitoring rules and receive smart notifications.

Price & stock monitoring

Amazon price tracker with stock alerts

Set up an Amazon product monitor in under two minutes. Tell us what to watch in plain English — we send the alert when the price drops or stock returns.

Start free How it works

WebMonitor.fyi tracks any Amazon product page and notifies you when the price changes, availability shifts, or the listing updates. The Amazon price tracker checks pages on the schedule you pick, ranging from every 30 minutes to once a day, and delivers alerts by email, Slack, or webhook. Useful for shoppers waiting on a sale, resellers tracking competitor pricing, and procurement teams watching catalog availability.

What it does

Plain-English criteria

Write the rule in normal language — "alert me when the price drops below $80" or "tell me when this is back in stock". No regex, no XPath.

Adjustable check frequency

30-minute and hourly intervals on Pro for time-sensitive deals, six-hour or twice-daily checks on Basic, daily for slow-moving items. Pick per monitor.

Multi-channel alerts

Email is the default. Slack via incoming webhook for team channels. A generic JSON webhook for piping into your own tools.

Check history with AI summaries

Every monitor keeps its last 50 checks, each with an AI summary of what it found. Useful when a listing changes the title, the seller, or the description without changing the price.

Multiple products per account

Watch one product on the free plan, three on Basic, or five on Pro — each monitor with its own criteria and check frequency, all in one dashboard.

How to set it up

Paste the Amazon product URL

From the WebMonitor dashboard, click Add New Monitor and paste the product page link.

Describe what to watch

Examples: "Alert me when the price drops by 10% or more." "Notify me when this product is available for Prime shipping." "Let me know when the seller changes."

Pick a frequency and a channel

30-minute checks (Pro) for limited-time deals, six-hour or daily for steady tracking. Email, Slack, or webhook for delivery.

Receive alerts when something changes

The alert includes an AI summary of what changed and a link straight back to the listing.

Common use cases

Wait-list a high-demand product and get notified when it restocks
Track competitor pricing across your category for repricing decisions
Monitor a gift list for the price to hit your budget
Watch a procurement SKU for supply changes that affect cost forecasts
Audit a third-party seller listing for unauthorized resale of your brand

Honest limits

WebMonitor reads what is publicly visible on the product page. Listings hidden behind a login wall, Amazon Business catalog pricing, and personalized prices that vary by account are outside what a public-page monitor can see.

Frequently asked questions

Does the Amazon price tracker work for any product?

Yes — any publicly accessible Amazon product page. That includes Amazon US, UK, Canada, Germany, Japan, and the other regional storefronts. Paste the product URL and the monitor handles the rest.

How often does it check the price?

Anywhere from every 30 minutes to once a day, depending on your plan and what you set per monitor. 30-minute checks (Pro) are useful during a deal or restock window; six-hour or daily is the steady default.

Will I get notified about a price increase?

Only if you ask. The criteria field accepts any condition: drops, increases, or "alert me on any change". For most shoppers, drop-only alerts cut noise.

Can I track stock as well as price?

Yes. Combine criteria — "alert me when this is back in stock under $60" works as one monitor. Or run separate monitors for stock and price on the same product.

What does WebMonitor see that Amazon's built-in price alerts do not?

Amazon's alerts are limited to specific products and a daily check cadence. WebMonitor watches any product page at intervals you set, fires alerts on conditions you write, and works across Amazon, Walmart, eBay, and any other retailer in one dashboard.

Is there a free plan?

Yes. The free plan includes one monitor with a one-time AI analysis, no card required. Upgrade to Basic or Pro for recurring checks, more monitors, and faster intervals.
