Features

HTTP, keyword, API, SSL, ping, port, cron heartbeat and domain-expiry monitoring, multi-region confirmation, status pages and alerting — on every plan.

Checks

• HTTP and keyword checks — a 200 response containing "Database error" is still an outage.
• API checks — assert on status, latency, headers and JSON body.
• SSL certificate expiry.
• Ping and TCP port checks.
• Cron heartbeats — alert when a job stops running.
• Domain expiry.

Alerting

Email, webhooks and chat. Before anyone is paged, a second probe location confirms the failure, so a flaky network path between one region and your server does not wake your on-call.

Status pages

Every account gets one, on your own domain if you want it. See status pages.

What the paid plans add

More monitors and seats, faster check intervals, more probe regions and a status page on your own domain. Never a monitor type. See pricing.
