Know the second your service goes down.
Systems Notification watches your sites, APIs, and servers around the clock — and tells you the moment something breaks, before your customers do.
No card required · 50 checks on the free plan
Monitoring and alerting, without the noise.
Point it at anything with a URL or an IP. We check it on a schedule, confirm a failure from a second location, and only wake you when it's real.
Uptime checks
HTTP, TCP port, ping, and keyword checks from multiple regions, as often as every 15 seconds. We re-test before alerting so a blip never pages you.
Alerts that reach you
Route incidents to email, SMS, Slack, Discord, PagerDuty, or any webhook. Set quiet hours and escalation so the right person hears about it.
Public status pages
Give customers a hosted status page on your own domain. Post incidents, show live uptime, and cut down the "is it just me?" support tickets.
Response-time history
Track latency over time and spot a service degrading before it falls over. Keep up to a year of history on paid plans.
SSL & domain expiry
Get warned before a certificate or domain registration lapses — the outages nobody schedules and everybody remembers.
API-first
Everything in the dashboard is available over a clean REST API, so you can create checks and pull status straight from your own tooling.
Up and running in about a minute.
Add a check
Paste a URL or host. Pick how often to check it and from which regions. That's the whole setup.
We watch it
Our checkers hit your endpoint on schedule and record status and response time. A failure is confirmed from a second region first.
You get alerted
The moment a check fails for real, the people you chose hear about it on the channels they actually watch — and again when it recovers.
A simple API for everything.
- Create, pause, and delete checks programmatically.
- Pull current status and uptime for any monitor.
- Receive incident events as signed webhooks.
- Token auth over HTTPS — no surprises.
