KEEP YOUR SITES ONLINE.
WE FEEL EVERY BEAT.
ONE SITE.
EVERY LAYER UNDER IT.
A website is not one thing. Checking it properly means asking the registry, the resolvers, the certificate and the page itself — and knowing which of them moved.
What a check reaches out to
Every run talks to services outside your infrastructure and outside ours. When one of them reports something different from last time, Pulse tells you which one — rather than a single red dot that could mean anything.
- Public DNS resolvers
- A · AAAA · MX · NS · TXT · CNAME · CAA · SOA
- Registry RDAP servers
- Expiry date · registrar status
- Your TLS endpoint
- Chain trust · hostname · protocol
- PageSpeed Insights
- Lighthouse · Core Web Vitals
WHATEVER YOUR GOAL.
Every check below exists and runs today. Nothing here is a roadmap item.
See all monitoring checksIs it up, and is it right? An uptime check records availability, response time and status code. A content assertion goes further and looks at what came back, which is how you catch a 200 response quietly rendering an error page.

A real TLS handshake, not a header sniff: chain trust, hostname match and protocol version. Separately, an RDAP lookup reads the domain's registration expiry straight from the registry. Both warn weeks out rather than the morning it breaks.
Certificate valid
Expires in 63 days
protocol: TLSv1.3
domain expires: 2027-04-11 (registry)
Both of these remember what they saw last time. A record you declared going wrong fails the check. A change you did not declare is reported and shown, but pages nobody — because a planned DNS edit is not an incident, and the next run treats the new value as normal.

Performance via Google PageSpeed, an authorised exposure scan, technical SEO and broken links. These never run on a schedule, on purpose: a third party moving a page should not wake you at 3am.
