Post-launch & redesign regressions
Catch broken layouts, missing UI, and dead buttons the moment a new site, campaign page, or release goes live — visual diffing flags what changed.
NorthDuty watches every client site like a QA engineer: visual regressions, broken buttons, dead checkout and signup flows, blank pages, and JS errors that uptime checks never catch. One dashboard across every client, alerts before the escalation, and reports that prove you're actively protecting their site.
Your worst day is the client calling to say their site is broken before you knew. The page returned a 200, so the uptime tool stayed green — but the checkout button was dead, a deploy blanked the homepage, or a CMS update broke the contact form. By the time someone notices, it's already a trust problem.
Across 10, 20, or 40 client sites, manual spot-checking doesn't scale and you can't watch every release. NorthDuty runs continuous, journey-level checks on the pages and actions tied to each client's revenue, so problems surface as an alert to you — not a complaint from them.
The failures that damage client trust almost always pass an uptime check.

Uptime tools confirm the server responds. NorthDuty verifies the site actually works — that the checkout completes, the form submits, the page renders, and nothing broke visually since the last release. Most client-trust incidents pass an uptime check.
Yes. NorthDuty is built for managing multiple sites and journeys from a single dashboard, so you can oversee your whole portfolio without logging into each site separately.
