Update fallout, caught visually
Screenshot diffs after plugin, theme, and core updates outline what changed on the pages that matter — so a broken layout is a diff in your inbox, not a client email.
WordPress Monitoring: Know Before Your Client Does
For an agency, the expensive WordPress failure is not downtime — it is the client discovering their own broken contact form, login, or checkout. NorthDuty monitors every client site from the outside: health checks every 5 minutes, real-browser journeys through the flows each site exists for, and screenshot diffs that show exactly what the last plugin update changed.

Every client site watched from the outside — update fallout caught before the client emails.
What WordPress monitoring covers
Every client site gets the same four layers, whatever its plugin stack.
The flows each site exists for
Contact forms, quote requests, logins, bookings, WooCommerce checkouts — run as real-browser journeys, AI-suggested per site or written in plain text.
Rendered health, not just pings
Every 5 minutes by default: uptime, SSL expiry, DNS, blank-page detection, broken resources, JavaScript errors — the failure modes a 200 response hides.
Client-ready proof
Public status pages and scheduled PDF/email reports show clients the retainer is working — and give you the evidence trail when something did break and you caught it first.
One workspace for the whole roster
Each client site is a project with its own journeys, baselines, and status page — and alerts that name the site and the failing step.
AI Journeys
Journeys suggested per site
NorthDuty reads each site and proposes the journeys worth monitoring — a checkout for the store, a quote form for the brochure site.
Alert Rules
Alert rules per client
Thresholds for health score, failed journeys, visual difference, and SSL expiry — routed to the right channel for each client team.
WordPress breaks quietly, and updates are usually the trigger
WordPress sites fail in ways uptime checks cannot see: a plugin auto-update conflicts with the theme, a form plugin stops delivering submissions, a page builder update shifts the layout, PHP errors blank a template while the homepage still returns 200. Multiply that by a roster of client sites on different plugin stacks, and 'is everything up?' becomes an impossible manual question.
NorthDuty answers it continuously and from the outside — no plugin to install on client sites, nothing to keep updated, and it keeps watching even when WordPress admin itself is down. Each site gets rendered health checks (uptime, SSL, DNS, blank pages, JavaScript errors), visual change detection against the previous baseline, and journeys that submit the contact form, log in, or complete checkout the way a visitor would.
Why agencies run NorthDuty across client sites
Built for the retainer model: many sites, mixed stacks, and a reputation that depends on catching breakage first.
- No plugin on client sites — nothing to install, update, or explain at handoff
- Priced for rosters: 20 journeys across 10 sites on the $79 Pro plan, 50 across 25 on Business
- Covers the whole roster — WordPress, WooCommerce, and the custom or headless builds too
- Update-day confidence: run every check on demand right after a maintenance window
- Alerts name the site and the step, so triage starts with the answer
- Status pages and scheduled reports turn monitoring into something clients can see
How agencies set it up
Ten client sites take an afternoon, not a sprint.
1
Add each client site as a project
Health monitoring starts immediately on each — uptime, SSL, DNS, blank pages, JavaScript errors, every 5 minutes by default.
2
Enable the journeys that match each site
Accept the AI-suggested flows or describe them in plain text — the contact form on the brochure site, checkout on the store, login on the membership site.
3
Confirm visual baselines
Key pages get screenshot baselines; every later capture is pixel-diffed so update fallout shows up as an outlined change.
4
Route alerts and schedule client reports
Per-project alert rules go to your channels (and the client's, if you want); scheduled reports and status pages keep the retainer visible.

Read Website Monitoring for AgenciesFrequently Asked Questions
Answers to common questions about this monitoring feature and when teams should use it.
What is WordPress monitoring?
WordPress monitoring verifies that a WordPress site is not just online but actually working: pages render, forms submit, logins succeed, checkouts complete, and the layout has not silently changed after an update. NorthDuty does this from the outside with health checks, real-browser journeys, and screenshot diffs.
Do I need to install a plugin on client sites?
No. NorthDuty monitors from the outside in a real browser, so there is nothing to install on the client's WordPress — no extra attack surface, no plugin to keep updated, and monitoring keeps running even when WordPress admin is unreachable.
Can it catch what a plugin update broke?
Yes — that is the most common WordPress failure it exists for. Journeys fail at the broken step within a cycle, visual diffs outline exactly what the update changed on key pages, and deployment monitoring can run every check immediately after your maintenance window.
How does pricing work for an agency with many client sites?
Plans are sized by journeys and sites, not per site: Starter ($29) covers 3 journeys across 3 sites, Pro ($79) covers 20 journeys across 10 sites, and Business ($199) covers 50 journeys across 25 sites — so a roster does not multiply the bill the way per-site pricing does.
Does it work for WooCommerce client stores?
Yes. Store projects get the full WooCommerce treatment — scheduled checkout journeys, Store API monitors, and visual diffs on product and checkout pages. See the dedicated WooCommerce monitoring page for details.
