E-Commerce

Track competitor prices automatically

Monitor pricing pages across thousands of products. Get notified the instant a competitor changes their price, launches a promotion, or updates stock availability.

E-commerce teams spend hours manually checking competitor websites for price changes. DiffTrac automates this completely — point it at any product page, select the price element, and get alerts on Slack, Telegram, or email the moment something changes. With checks as fast as every 5 seconds, you'll know about price drops before your competitors' own customers do.

What you can do

Track any price on any website

Works on Amazon, Shopify, WooCommerce, custom stores — any website that displays a price. No API integration needed, just point and click.

Stock availability monitoring

Know instantly when a competitor's product goes out of stock or comes back in stock. Monitor 'Add to Cart' buttons, stock counters, and availability badges.

Historical price tracking

See the full history of price changes over time. Identify pricing patterns, seasonal trends, and promotional cycles across your competitive landscape.

Multi-channel instant alerts

Get notified via Slack, Discord, Telegram, email, or webhook. Route different products to different channels — urgent price drops to Slack, daily digests to email.

How it works

01

Enter a product URL

Paste the URL of any product page you want to track. DiffTrac takes a screenshot and lets you click on the price element.

02

Select what to track

Click on the price, stock status, or any other element. Name each selector and choose how often to check — from every 5 seconds to once a day.

03

Get alerted on changes

When the price changes, you get an instant notification showing the old price vs. the new price, with a direct link to the page.
