How It Works

Monitoring Made Simple — Set Up in 5 Minutes

Add a URL, choose your check frequency, set your alert preferences. ChangeTower handles the rest.

Three Steps to Never Miss a Change

From URL to actionable insight in minutes - not days.

01

Add Pages to Monitor

Paste any URL or upload a list. Choose what to track: visual changes, text content, HTML source, HTTP headers, or file downloads. Set your check frequency from every 15 seconds to once a week.

02

Configure Detection Rules

Fine-tune what counts as a change. Ignore dynamic ads, cookie banners, or timestamps. Focus on the specific CSS selectors, keywords, or page regions that matter to your team.

03

Get Intelligent Alerts

When a meaningful change is detected, ChangeTower sends a detailed diff to your preferred channel - email, Slack, Teams, SMS, or webhook - with highlighted before/after context.

04

Review & Archive Changes

Browse a timestamped history of every change with side-by-side visual diffs, highlighted text diffs, and full-page screenshots archived for compliance and audit trails.

05

Collaborate & Act

Share change reports with your team, assign follow-up tasks, and integrate with your existing workflow tools. Everyone stays informed without duplicating effort.

What Can You Monitor?

ChangeTower watches the web the way your team would - if they had infinite time and attention.

Visual Changes

Pixel-level screenshot comparison catches layout shifts, image swaps, design changes, and visual regressions across any page.

Text & Content Changes

Track additions, removals, and edits to visible page text - from pricing updates to policy changes to product descriptions.

HTML & Source Changes

Monitor the underlying code for script injections, metadata updates, structured data changes, or schema modifications.

HTTP Header Changes

Watch for server configuration changes, redirect modifications, security header updates, and caching policy shifts.

File Downloads

Track changes to PDFs, spreadsheets, documents, and other downloadable files hosted on monitored pages.

Keyword Triggers

Set up alerts for specific words or phrases appearing or disappearing from any monitored page - like competitor mentions or compliance terms.

Noise Filtering Built In

The web is noisy. Cookie banners, ad rotations, dynamic timestamps, and session tokens create false alerts on every check. ChangeTower's intelligent filtering lets you define exactly what matters - and ignore everything else.

  • Exclude specific CSS selectors from monitoring
  • Ignore changes below a configurable threshold
  • Filter out dynamic elements like ads and timestamps
  • AI-powered change significance scoring
