HTTP / HTTPS monitoring
Monitoring that tells you why.
A slow page is only half the answer. CuliPulse breaks every request into its real stages — DNS, connect, TLS, server wait, download — and tells you, in plain words, where the time actually went.

Find out why, on demand
Stop guessing where the time goes.
Every check records the full timing breakdown — DNS, connect, TLS handshake, server wait and download — and turns it into a plain-language verdict, not raw numbers you have to decode.
Need a fresh read right now? Hit Diagnose now and an agent runs a cold, one-shot probe and reports the phase-by-phase timing, usually within a minute.
Beyond “is it up?”
Check what the response actually says.
Match an exact code, a whole class, or a list — and decide which ones count as healthy.
Assert the body contains (or doesn't contain) text, or matches a regular expression.
Pull a value out by path and check it equals, contains, exists, or is greater / less than expected.
Assert a header equals, contains, matches a pattern, or simply exists.
Send a Bearer token or Basic credentials with every check — stored encrypted, never shown back.
Flag “up but slow” before your users feel it, as a distinct degraded state.
Plus custom methods, request headers and bodies, a follow-redirects toggle, and a default User-Agent you can override.
Fewer false alarms
Confirmed from several places before you're paged.
Add more than one checkpoint and CuliPulse waits for several of them to agree before it calls something down.
One bad network hop won't wake you up — and when we do alert, it's real.
SSL / TLS
Never get surprised by an expired certificate.
Turn on certificate monitoring and we warn you a set number of days before it expires — with the exact days-left and expiry date right on the monitor. One checkbox, no maths.
It rides on the same monitor as your status, body and header checks, so one endpoint means one monitor and one alert.
Watch your first endpoint in 2 minutes.
Add an HTTP monitor, see the phase breakdown, and get alerts you can trust.
