Uptime monitoring
Know the minute your site goes down.
We check every site every minute from multiple locations, and alert you only when it is really down. Public status pages included. Unlimited monitors, free.

Everything you need to stay up
Every minute, multiple locations
HTTP(S), keyword and TCP port checks from multiple locations, with response times and 60 days of history.
Down means down
Alerts only when every location fails twice in a row. Cloudflare blocks are recognised and ignored, not counted as downtime.
Unlimited monitors
Paste thousands of domains at once, or import them from Cloudflare, Namecheap, OpenPanel, cPanel and Plesk.
Alerts where you are
Email, Slack, Discord, Telegram and signed webhooks. Pause any time; maintenance windows mute alerts by themselves.
Status pages
A public page for your customers: your logo and colours, your own domain, incident updates, email subscribers, RSS and badges.
Checks your way
GET, HEAD or POST, custom headers, basic auth, expected status codes, and keywords that must or must not appear.
Secure account
Two-factor authentication, passkeys and an activity log of every sign-in and change.
Fast to set up
Sign up, paste your domains, done. Checks start within a minute and alerts are on by default.
Also watched, with no setup

Questions
How often are sites checked?
Every minute, from multiple locations.
How many monitors can I add?
As many as you need. Paste thousands of domains at once, or import them from your control panel or domain provider.
Will I get false alarms?
A monitor is marked down only when every location fails two checks in a row. Responses where Cloudflare blocks our checker are ignored instead of counted as downtime.
How do I get alerted?
By email, Slack, Discord, Telegram or any webhook. You can pause alerts any time, and scheduled maintenance mutes them automatically.
Can I show uptime to my customers?
Yes. Every account gets a public status page you can style and put on your own domain, with incident updates, email subscribers, RSS and badges.
Does it cost anything?
No. Monitors are unlimited and there is no credit card to enter.
