Everything you need.
Nothing you don't.

Instant, multi-channel alerts

The moment downtime is confirmed, every channel you care about hears it. Quiet hours, escalation chains, and per-monitor rules baked in.

Common questions.

How fast are alerts?+
Seconds after a failure is confirmed. We use direct SMTP, native Slack and Discord integrations, and webhook fan-out - no polling, no batching.
How do you avoid false alarms?+
Every failure is re-checked with configurable retries before an alert fires, and degraded latency is tracked separately from hard downtime.
Can I switch from UptimeRobot or Pingdom?+
Yes - paste your URLs and you're set. Adding a monitor takes seconds, and the API is included if you want to script a bulk import.
Is it really free?+
Yes. Every feature is included for every team: 60-second checks, status pages, incidents, on-call, audit log and API. No card, no paid tier. The only caps are fair-use limits (50 monitors and 25 members per team).
I run an agency - can I white-label status pages for clients?+
Yes. Unlimited status pages with custom domains and full branding removal are included, so each client gets a status page under your name on their own domain. See PULSX for agencies.
