Synthetic examples - not live data.
One platform, every signal you care about
From simple uptime pings to keyword checks, multi-region confirmation, and maintenance windows that keep your metrics honest.
-
Checks that match reality
HTTP/HTTPS with custom methods and headers, TCP ports, ICMP ping, SSL and domain expiry, DNS drift, and cron-style heartbeats when a job must report in.
-
Fewer false alarms
On Pro and Business, incidents can wait for agreement across regions before paging anyone - so one flaky POP does not wake the team.
-
Dashboards teams actually use
Uptime and latency trends, incident timelines, exports when you need a paper trail, and tags to group large fleets of monitors.
Reach the right channel, every time
Wire Slack, Discord, Microsoft Teams, Telegram, PagerDuty, webhooks, and email. Tune what fires on down, recovery, SSL thresholds, and slow responses.
