The moment your site goes down, your phone knows — before your users do. Uptime, SSL expiry, and latency monitoring with instant push and email alerts. Free to start, up in under a minute.
How it works
No setup, no infrastructure — add a target and we handle the rest.
Enter any hostname, URL, or host:port. Tap to run a check right from your phone — no cloud, no account needed. Ideal for on-the-spot network diagnostics.
On Pro, our servers check your targets every 5 minutes — even when your phone is off or out of signal. Your monitoring never sleeps.
Get push and email notifications when a target goes down, comes back up, latency spikes, or SSL is expiring. Use traceroute and full cert details to diagnose fast.
What we check
Point it at any hostname, URL, or host:port. We tell you what’s wrong before your customers do.
See days remaining on every cert. Get warned before expiry — with enough lead time to renew without drama.
Every check measures response time. Get alerted when latency spikes — often the first sign of an overloaded server.
HTTPS and HTTP status code checks — catch 5xx errors and unexpected redirects. Go lower-level with TCP port monitoring for databases, mail servers, and custom services.
With Pro, our server checks your targets every 5 minutes — even when your phone is off. Your monitoring never sleeps, never misses a check.
Instant push alerts on downtime, recovery, latency spikes, and SSL expiry milestones. Know the moment something’s wrong — and when it’s resolved.
On-demand traceroute to diagnose routing issues. Pinpoint exactly where in the network the connection breaks down.
