Keep uptime and SSL
Every check confirms the site responds and that the certificate and DNS are healthy.
NorthDuty vs updown.io
updown.io is a simple, affordable uptime and SSL monitor with response-time tracking. If you are comparing alternatives, the question is whether you also want rendered page-health checks, visual change detection, and user journeys as you grow.
Simple uptime and SSL, plus the rendered page health and journeys a status check misses.
Where simple, affordable uptime fits
updown.io is deliberately minimal: it checks that a URL responds, tracks response time and an Apdex-style score, and watches SSL expiry, at a very low price. For a personal site or a simple service, that is often all you need.
The gap shows up as the site becomes more business-critical. A page can respond quickly and still be blank, a button can disappear, or a checkout can stop completing — and a response-time-and-status check will report everything as healthy while conversions quietly stop.
Why deeper checks matter as you grow
Once a site drives real revenue or signups, 'it responded in 200ms' is not enough. You need to know the page actually rendered, the key elements are present, and the important journeys still complete.
NorthDuty keeps the simple signals — uptime, response health, SSL, DNS — and renders each page to catch blank pages, JavaScript errors, and broken resources, then adds screenshot-based visual diffs and plain-text or AI-suggested user journeys, with alerts to email, Slack, and more.
NorthDuty vs updown.io
Both cover uptime and SSL simply; the difference is depth into rendered page health and journeys.
| Criteria | NorthDuty | updown.io |
|---|---|---|
| Core focus | Website health, visual changes, and journeys with uptime, SSL, and DNS | Simple uptime, response time, and SSL monitoring |
| Catches 'up but broken' | Yes — blank pages, JS errors, broken resources, and failed journeys | Focused on availability and response time rather than rendered UI failures |
| Visual change detection | Scheduled screenshot diffs against a baseline | Not a focus |
| User journeys | Plain-text or AI-suggested multi-step journeys | Not a focus |
| Best for | Sites where important pages and flows drive revenue or signups | Personal sites and simple services wanting low-cost uptime |

What is a good updown.io alternative?
If you want more than simple uptime and response-time checks, NorthDuty adds rendered page-health checks, visual change detection, and user journeys while still covering uptime, SSL, and DNS.
Does NorthDuty track response time like updown.io?
Yes. NorthDuty checks availability and response health, and also renders the page to catch failures that a status-and-timing check would miss. There is even a free response-time checker tool.
When should I move beyond simple uptime monitoring?
When your site drives revenue or signups. At that point 'it responded' is not enough — you need to know the page rendered and the key journeys still complete.
