Built because nobody was watching
VitalSentinel watches uptime, Core Web Vitals, search visibility, and traffic in one place – and tells you the moment one of them moves the wrong way.
Why I built VitalSentinel
I lead a web development team and do technical SEO for large sites, so I see both ends of this – and the same thing kept happening. A deploy ships a stray noindex tag. A CDN rule quietly doubles load times. A robots.txt changes during a migration. Nobody finds out until the traffic graph has already fallen off a cliff – and more often than not, the client notices before I do.
The tools to catch all of that already existed. That was the problem. Uptime in one product, Core Web Vitals in another, search data in a third, analytics in a fourth. Five subscriptions, five dashboards, five logins – and still nothing that would simply tell me something had changed.
So I built what I wanted to buy: every signal in one platform, checked continuously, with an alert the moment one of them moves. The gap between something breaking and a human noticing should be minutes, not days. That is the whole product.
The first generation proved the idea worked. The second, live since July 2026, is the version I actually meant – a far deeper analytics and Search Console suite, workspaces for running whole portfolios, and a rebuilt interface across all of it.

The problem
Five subscriptions, five dashboards, and still no answer to "did anything change today?"
The build
Every signal folded into one platform, checked continuously instead of whenever someone remembers to look.
The launch
VitalSentinel goes live with nothing locked behind a higher tier – even the free plan gets every module.
VitalSentinel 2.0
A far deeper analytics suite, workspaces for whole portfolios, and a rebuilt interface across every module.
What we believe
Four principles that decide what gets built and what it costs.
Ten modules, one login
Six monitors and two analytics – all eight on every plan. You should never have to decide which signals you can afford to watch.
Detection speed
What a problem costs you is a function of how long it goes unnoticed. Everything here is built to shorten that window.
Honest pricing
Public, flat prices. You pay for capacity – domains, data, check frequency, history – never for features locked behind a higher tier.
Privacy by default
Our analytics are cookie-free by default, so in that mode nothing is written to your visitors' devices. Private by design, not by workaround.
