Website Monitoring That Catches Problems Before Customers Do

Monitoring you can actually trust. Three layers working quietly in the background of every project: website health checks every 5 minutes by default, scheduled screenshot and visual-diff reviews, and AI-suggested user journeys you can review and edit in plain text — always in your control, never a black box. Add your base URL. We'll take it from there.

Traditional uptime monitoring isn't enough

A website can be technically online while the customer experience is still broken. That is where revenue leaks and support issues begin.

Websites can be online but still broken for customers
Screenshots and pixel diffs surface when important pages changed unexpectedly
Login, signup, and checkout flows can fail after several steps
JavaScript errors, failed resources, and API calls can leave visitors with blank or unusable pages

How NorthDuty solves the problem

Three monitoring types — uptime, UI changes, user journeys — running together on every project.

Uptime & Website Health

Every 5 minutes by default, with 1, 5, and 15 minute cadences available: HTTP status, SSL, DNS, redirects, response timing, Core Web Vitals, blank-page detection, broken resources, JavaScript errors, and first-party API calls — all in one check.

How it works

Designed to be easy for technical and non-technical teams.

1

Create a project with your base URL

Add your site's base URL and NorthDuty sets up a project around it — uptime monitoring starts immediately.

2

All three monitoring types run on a schedule

Website health runs every 5 minutes by default, screenshots and visual diffs can run daily or weekly, and user journeys use the cadence you choose. Defaults work out of the box; tune anything in project settings.

3

See results and alerts in real time

Each run is timestamped and reported in the dashboard, with diff images, journey transcripts, and full uptime context to help you respond fast.

Why we built NorthDuty

Most monitoring tools tell you when a server is down. They stay silent when the checkout button disappears, the login form throws a JavaScript error, or a deploy quietly wipes the hero CTA.

We kept watching teams discover broken buttons, blank product pages, and failed signups through angry customer emails instead of their monitoring dashboard. NorthDuty is the tool we wanted: a single check on whether the customer experience still works — not just whether the server replies.

The NorthDuty team

Built for teams whose revenue depends on their website

Frequently Asked Questions

Answers to common questions about NorthDuty and website monitoring.

What is website monitoring?

Website monitoring is the practice of checking whether important pages, visuals, and user journeys are available, usable, and unchanged for visitors. NorthDuty covers all three from a single project.

Why is uptime monitoring not enough?

Because a website can be online while key customer actions are still broken. Missing buttons, failed logins, checkout problems, and JavaScript errors all happen without a full outage.

How does NorthDuty detect issues?

Website health checks every 5 minutes by default return HTTP, SSL, DNS, blank-page detection, broken resources, JavaScript errors, and first-party API call results. UI change monitoring uses screenshots and pixel diffs. User journeys run AI-suggested or plain-text multi-step flows on a schedule.

How often does NorthDuty check websites?

Website health runs every 5 minutes by default and can be set to 1, 5, or 15 minutes. Screenshots and visual diffs support daily or weekly schedules. User journey cadence is configurable per project.
