What it does

Ten tools that measure a network and then tell you what the numbers mean. Every run is kept, and every run is judged again — against today's thresholds — each time you open it.

PulseRe-walks a path continuously, so a router losing one packet in twenty stops being invisible.
Health CheckEight checks and a plain verdict: link, address, router, neighbours, DNS, internet, public address, VPN.
CertificateExpiry, trust, hostname, chain and cipher — including whether the server sent its intermediates.
DNSA, AAAA, MX, TXT, PTR and more, with TTLs and the server that answered.
WHOISRDAP where a registry speaks it, port 43 where it does not.
PingRound trips, loss and RFC 3550 jitter, charted as they arrive.
TracerouteEvery hop, over ICMP, UDP or TCP to port 443.
Path MTUThe largest packet that gets through, believed from a router that names it and searched for when the path stays silent.
Overview & RoutesInterfaces, addresses, resolvers, the routing table, VPN and proxy state.

The part other tools skip

When a hop reports loss, there are two different things that can be happening: the router is dropping traffic, or it is passing traffic along perfectly and merely rate-limiting its own ICMP replies. One is a fault on your path. The other is a router doing exactly what it is configured to do.

Every comparable tool paints both red. Pulse tells them apart, and says which it found.

How to read what it tells you

Pulse makes judgements — which hop is at fault, whether a certificate will outlive your maintenance window, whether a name server that is not answering matters. The manual gives the rule behind each one, so you can disagree with it knowingly.

Pulse Pro

Every measuring tool is free, and so is the history of the last seven days. Pro adds an AI reading of a run written for a ticket, a link test between two of your own devices, two interfaces measured side by side, comparison of saved sessions, picture and CSV export, and full history synced through your own iCloud.
