DNS verification
Confirm ownership with a TXT record before a new page monitor starts running.
Visual regression monitoring
Regression monitoring for changes uptime checks cannot see.
InfraBeacon captures verified public pages, compares them against a known baseline, and alerts when visual differences pass your configured tolerance. It is built for pages where broken layout, missing content, or unexpected visual drift matters.
Overview
What this tool is for
Use regression monitoring when a page can be technically up but visually wrong. InfraBeacon verifies ownership, stores private captures, compares them with baselines, runs safe scripted test plans, confirms significant changes, preserves history according to plan limits, and keeps captured images inside the account-backed monitoring workflow.
Signals
What it monitors
Baseline captures
Mark the latest or a previous known-good capture so later captures have a clear comparison point.
Test plans
Run safe browser steps before capture to reveal menus, dynamic states, or form-driven pages.
Tolerance settings
Set how much visual change should be allowed before alerting.
Capture history
Review recent captures to understand when a visual change appeared.
Private captures
Keep captured page images tied to your account rather than public pages.
Confirmation captures
Confirm material visual changes before alerting so transient rendering noise is less distracting.
Change alerts
Receive email alerts when visual differences exceed the configured threshold.
Page verification
Use regression checks alongside uptime data to catch layout and content problems.
Controls
What you can configure
Ownership verification
Use the generated DNS TXT record and verification action before activating new or changed hosts.
Resolution presets
Choose desktop, laptop, Full HD, tablet, mobile, or a saved custom viewport for captures.
Scripted steps
Wait, assert text, click, hover, scroll, type, select, check boxes, accept cookies, reload, go back, or wait until idle before capture.
Baseline control
Set the latest capture or any valid previous capture as the baseline when the expected page changes.
Sensitivity and cadence
Tune tolerance from 1% to 50% and schedule capture intervals according to account limits.
History controls
Reset captures, delete monitors, update test plans, and keep retention aligned with free or paid access.
Workflow
How it works

Review changes
Use the dashboard to compare captures, update baselines, reset history, and investigate alerts.
Use Cases
Where it fits
Marketing pages
Catch missing hero content, layout breaks, and visual drift after deployment.
Customer portals
Monitor pages where uptime alone does not prove the experience is correct.
Regression checks
Keep a visual history around important releases without building a full testing pipeline.

FAQ
Questions about regression monitoring
What is regression monitoring?
Regression monitoring captures a page on a schedule and compares it with a baseline so visual changes are easier to detect.
Why is DNS verification required?
Verification helps confirm that the account is allowed to monitor the hostname before scheduled captures begin.
Can I control sensitivity?
Yes. Each regression monitor can use tolerance settings so minor rendering noise does not create unnecessary alerts.
Can monitors run browser actions?
Yes. Test Plans can run predefined safe steps such as waits, text checks, clicks, hovers, scrolls, typing, selects, checkbox changes, cookie acceptance, reloads, back navigation, and idle waits before capture.
How long are captures retained?
The free allowance includes 3 days of retention. Paid access expands retention according to the current plan capability.
Can I update the baseline?
Yes. You can set the latest capture or a previous capture as the baseline when an expected visual change ships.
