How does the visual selector work?

We load the actual webpage in a live preview. Just click or drag to select the elements you want to monitor. We automatically generate the right selector — no technical knowledge needed.

Can it monitor JavaScript-rendered pages?

Yes. We use a real Chrome browser engine to render pages, so dynamic content loaded by JavaScript, React, Vue, or any framework is fully captured.

What notification channels are supported?

Email is included on all plans. Starter adds Slack, Discord & Telegram. Pro adds all channels including Teams and webhooks. Business adds SMS & WhatsApp via Twilio.

How often does it check for changes?

It depends on your plan. Free checks every hour, Starter every 10 minutes, Pro every 5 minutes, and Business every minute. You can set different intervals for each monitor.

Is there a free plan?

Yes! The free plan includes 3 monitors with hourly checks and email notifications. No credit card required. Upgrade anytime if you need more.

How to Get Notified When Out-of-Stock Products Are Back

Limited edition sneakers, popular electronics, event tickets — high-demand products sell out fast. Manually refreshing pages hoping to catch a restock wastes time and rarely works.

With a website change monitor, you can track the availability status of any product and get an instant notification the moment it's back in stock.

How Stock Monitoring Works

Website change detection tools check a page on a schedule (as often as every minute). When the content of a monitored element changes — for example, a button text switching from "Sold Out" to "Add to Cart" — you get an alert.

This works on any website, including:

Amazon, eBay, and other marketplaces
Brand websites and direct-to-consumer stores
Ticket platforms (Ticketmaster, StubHub, etc.)
GPU and electronics retailers

Step-by-Step Setup with Pulse

1. Find the Product Page

Navigate to the product page that shows the availability status. This could be a button, a badge, or a text element.

2. Create a Monitor

3. Select the Availability Element

Use the visual selector to click on the element that shows stock status. Common elements include:

"Add to Cart" / "Sold Out" buttons
"In Stock" / "Out of Stock" text
Availability badges

4. Set an Alert Condition

Instead of being notified on every change, use the "Contains" alert condition:

Set it to alert when the text contains "Add to Cart" or "In Stock"
This way, you only get notified when the product is actually available — not when the page layout changes

5. Set Check Frequency

For high-demand products, check as frequently as possible:

Business plan — every 1 minute
Pro plan — every 5 minutes
Starter plan — every 10 minutes
Free plan — every 60 minutes

6. Choose Instant Notification

For restocks, speed matters. Use:

Telegram — push notifications hit your phone instantly
Discord — great if you're monitoring restocks with friends
Slack — perfect for team-based purchasing

Tips for Better Stock Monitoring

Monitor Multiple Retailers

Create separate monitors for the same product on different stores. This increases your chances of catching a restock.

Use JavaScript Rendering

Many modern ecommerce sites load product data dynamically. Enable "JavaScript Rendering" in Pulse to ensure the stock status is captured correctly.

Track Price + Availability Together

Use multi-element selection to monitor both the price and the stock status. This way, you know not just when it's back, but at what price.

Real-World Examples

PS5 / Xbox restocks — Monitor product pages on Amazon, Best Buy, Walmart
Limited sneaker drops — Track Nike SNKRS, Adidas Confirmed, or retailer pages
Concert tickets — Monitor Ticketmaster for released tickets or price drops
PC components — Track GPU availability on Newegg, B&H Photo, or Micro Center
