Change Monitoring
Know how the web changes over time.
Build a timestamped record of pages that matter.
Important pages change without notice — pricing, policies, regulatory guidance, competitor messaging. Backdrop lets you build a longitudinal archive by re-capturing pages over time, giving you a concrete record of what changed, when, and how.
Periodic re-archiving
Capture the same page at regular intervals. Each snapshot is independently timestamped and stored.
Screenshot comparisons
Compare screenshots from different dates to immediately see visual and content changes.
Full HTML preservation
Archive the full HTML source at each capture to enable precise content diffing.
Annotation per capture
Note what changed and why it matters on each archive snapshot.
Collections per monitored page
Group all snapshots of a specific page into a collection for easy longitudinal review.
Shareable change records
Share a collection of snapshots as a documented change history.
How it works
Identify pages worth monitoring
Competitor pricing, regulatory pages, product announcements, policy documents, vendor terms.
Create an initial archive
Capture the baseline state of each page with a timestamp.
Re-archive on your cadence
Weekly, monthly, or whenever you want a new snapshot. Each capture is independently stored.
Compare and act
Review screenshots side-by-side, add analysis, and share the change record with stakeholders.
“We monitor six competitor pricing pages. Backdrop gives us a historical record we can share in strategy meetings. It turned a manual, error-prone process into something systematic and reliable.”
