The 3am alert you can trust.
We check your sites, API servers, mail servers, name servers and SSL/TLS certificates, and confirm every failure from another continent before we contact anyone.
No credit card. Free forever for personal projects.

Rather more than uptime
Most monitors watch HTTP and stop there. Your mail server going quiet or your IP landing on a blocklist costs you just as much, and usually takes longer to notice.
- HTTPS pages, APIs, keyword matching
- SMTP incoming email, handshake and STARTTLS
- DNS resolution and record changes
- Email blocklists your sending IP and domain
- SSL/TLS certificate expiry
- Ping reachability and packet loss
- TCP port any host, any port, and what it says
- Heartbeat cron jobs that stop
- Domain blocklists pi-hole and AdGuard block your site
- WebSocket the socket opens, and still says something
Be the first to know. Not the fifth person to be woken.
A single failing check is often the network between us and you, not your site. So we never alert on one.
Confirmed from another continent
Before anyone is contacted, the failure is re-checked from another continent. One probe failing tells you about one probe, and most single failures are the network in between, not your site.
One alert, not thirty
Tell us your website depends on your server. When the server goes down you get one message about the server, not one for every site on it.
The right person, at the right time
Text yourself immediately, Slack the team after two minutes, email the owner after forty-five. If it recovers first, the later messages never go out.
