Everything that can go wrong with a website, watched in one place

Uptime checks every minute

HTTP(S) checks with the expected status, an optional keyword that must (or must not) appear, redirect rules and a response-time limit. Ping, TCP port and DNS checks are there too.

Confirmed failures

A failure is checked again before we alert you, and flapping sites are grouped, so alerts mean something.

Response-time history

See how fast every site answers, over 24 hours or 7 days, and keep the history for up to a year.

SSL certificates

We read the certificate, check the chain and the hostname, and warn you before it expires, and again when it renews.

Domain registration

The registrar, the expiry date and the registry status of your domain, with early warnings. A domain that lapses takes your site and your email with it.

Malware and phishing lists

Your site, the final address after redirects and sampled pages are checked against known malware and phishing lists.

Content integrity

We look for injected scripts, hidden links, spam keywords, a Japanese keyword hack and cloaking, where search engines see something different from visitors.

WordPress checks

Core, theme and plugin versions, known vulnerable plugins and risky exposed files such as debug logs.

Email, Telegram, Slack, webhook

Send alerts where you already work. Signed webhooks make it easy to connect your own tools. Slack and webhooks are on the paid plans.

Quiet hours and throttling

Choose when not to be disturbed. Critical problems can still get through, and a burst of alerts is summarised instead of flooding you.

Incidents with a timeline

Every incident shows when it started, was confirmed, who was notified and when it ended. Acknowledge it so everyone knows it is handled.

Maintenance windows

Plan downtime ahead: incidents are recorded but nobody is paged, and planned downtime can be left out of your uptime figure.

Team members

Invite colleagues as owners, admins or viewers.
