Uptime & reliability monitoring

Know when anything breaks — not just your homepage.

CuliPulse checks your public sites from the outside, and your private, internal services through a small agent you install. You only hear from us when something's really down — no pile of false alarms.

The gap

Most monitors only see your front door.

They ping your public URL from the outside and call it a day. They can't see your database, your internal API, or anything behind a login — exactly the things that take your product down without your status page noticing.

How it works

Public and private, in one place.

Your public sites

We check them from the outside, from more than one place, so a single bad network hop doesn't page you.

Your private & internal services

Install a small agent with one command. It runs the same checks from inside your network and reports back — no firewall holes, no exposing anything to the internet.

Fewer false alarms

We only wake you up when it's real.

Add more than one checkpoint and CuliPulse confirms a failure from several places before it alerts you. Less noise, less alert fatigue, more trust in the page.

Less setup

Point it at your network or your cloud — it finds the rest.

Have an agent scan a network range, or give it read access to your AWS account, and CuliPulse finds what's running — open ports, servers, databases, load balancers — and lets you adopt them as monitors in a click, labelled and organized.

Security

The secrets you give us stay secret.

Monitoring real services means trusting us with the occasional API key or password. We encrypt the credentials you add at rest (AES-256-GCM), never show them back to you, and never hand them to another customer's agent. How we protect your data →
