When your site breaks, we honk.
Uptime monitoring from 11 cities, with every outage confirmed before anyone gets woken up.
Free while we launch. No card.
Checked from 11 cities
You see the response time from each city, so you know whether it is slow for everyone or only in Sydney.
Running in a minute
Paste a URL, choose how you want to hear about it. Nothing to install on your server.
Alerts that get through
Email, SMS, a phone call, Slack, Discord, Telegram, PagerDuty. They repeat until someone says "on it".
One slow city is not an outage.
Every check runs from several cities at once. One city having a bad moment is not an outage. Two cities agreeing is.
One city fails
- Nuremberg200 OK
- Singaporetimeout
- Sydney200 OK
Still up. Nobody paged.
Two cities fail
- Nuremberg200 OK
- Singaporetimeout
- Sydneytimeout
Down. Alert sent.
When it is real, you hear about it by email, SMS, a phone call or the chat app you already live in.
What your customers see
One page with everything that matters to them, on your own domain if you like. Ninety days of history, the incidents in plain words, and a button to get an email when something changes.
When you're down, it says so before the support inbox fills up.
Every check type, in every plan.
Websites and APIs, down to a value in the JSON reply. A word that should or should not be on a page. Ping, TCP and UDP ports. DNS records that should not change. Certificates and domain registrations before they lapse. Cron jobs that stop phoning home. GitHub, Cloudflare and friends, so you stop blaming your own code.
Basic checks
- HTTPS and HTTP
- Full page load
- Keyword on page
- Ping
- TCP port
- UDP port
- DNS record
- SSL certificate

- Certificate expiry warnings
- Custom headers and body
- Expected DNS answers
The boring parts, done properly
Heartbeats for cron jobs
Your backup script calls a link when it finishes. If that call never comes, we honk.
Maintenance windows
Plan downtime. Checks keep running, but nobody gets paged and nothing counts against uptime.
Incidents with a cause
Each incident records what failed, where it was seen, who acknowledged it and any notes.
Team members
Invite people as admin, editor or viewer. Everyone in one workspace, or several.
Resellers
Your brand, your colour, your customers, one bill. Your customers never see our name.
API and automation
Create monitors, pause them, subscribe to events. Works with Zapier, Make and n8n.
SSL and domain expiry
A warning weeks before a certificate or a domain registration runs out.
SMS and voice calls
For the alerts that really matter. We confirm the number first, so nobody gets spammed.
Checked from around the world
Probes in Europe, Asia, Australia, Africa and the Americas, each checking your site on its own.
