Add a URL, choose your check frequency, set your alert preferences. ChangeTower handles the rest.
From URL to actionable insight in minutes - not days.
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.
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.
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.
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.
Share change reports with your team, assign follow-up tasks, and integrate with your existing workflow tools. Everyone stays informed without duplicating effort.
ChangeTower watches the web the way your team would - if they had infinite time and attention.
Pixel-level screenshot comparison catches layout shifts, image swaps, design changes, and visual regressions across any page.
Track additions, removals, and edits to visible page text - from pricing updates to policy changes to product descriptions.
Monitor the underlying code for script injections, metadata updates, structured data changes, or schema modifications.
Watch for server configuration changes, redirect modifications, security header updates, and caching policy shifts.
Track changes to PDFs, spreadsheets, documents, and other downloadable files hosted on monitored pages.
Set up alerts for specific words or phrases appearing or disappearing from any monitored page - like competitor mentions or compliance terms.
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.
