Website Change Monitor

Get notified the moment any webpage changes — price, content, or status

Website Change Monitor watches pages on a configurable schedule, diffs the content, and alerts you via email, Slack, or webhook when something changes. Monitor competitor pricing pages, regulatory announcements, job boards, or your own production pages for unexpected modifications.

The Problem

Sound familiar?

Manually checking competitor pricing or regulatory pages is tedious and unreliable

No easy way to get alerted when a job board posts a new opening matching your criteria

Production pages change unexpectedly after deploys and no one notices until users complain

The Solution

Website Change Monitor fixes this.

CSS Selector Targeting

Monitor a specific element on a page (price div, table row, announcement banner) instead of the whole page — fewer false positives.

Visual & Text Diff

Side-by-side visual screenshot diff and highlighted text diff included in every alert so you see exactly what changed at a glance.

Flexible Schedule

Check every 5 minutes, hourly, daily, or on a custom cron. Higher-frequency checks available on paid plans.

How It Works

Set up in under 2 minutes. No complex configuration.

JavaScript Rendering

Headless browser option for SPAs and pages that load content via JavaScript — no missed changes on React or Vue pages.

5

Alert Routing

Route alerts to email, Slack, Microsoft Teams, or any webhook. Conditional alerts based on keyword matches in the diff.

Why not the alternatives?

Same result. A fraction of the price.

Frequently Asked Questions

How does it handle dynamic ads or timestamps?
