Know instantly when your devices go silent.
PushMonitor is heartbeat-based uptime monitoring for devices behind firewalls. Just POST or email a periodic "I'm alive" — we alert you the moment it stops.
Free tier includes 5 devices. No credit card required.
How it works
1. Send a heartbeat
Your device sends a simple HTTP POST or email every few minutes. One URL, one token, zero agents to install.
2. We watch the schedule
Each device has a configurable check-in schedule with a grace period. Miss a heartbeat and an incident opens automatically.
3. Get alerted
Email, SMS, or webhook — your choice. Escalate to the next channel if the first one goes unread.
Built for operators who can't afford blind spots
Flexible schedules
Simple interval or cron expression. Per-device or per-group.
Group monitoring
Organize devices into groups with shared schedules and alert rules.
Multi-channel alerts
Email, SMS (Twilio), and webhooks with HMAC-signed payloads.
Escalation policies
Define repeat intervals and max repeats. Escalate if unacknowledged.
Incident timeline
Full delivery log per incident with response codes and errors.
No agents required
Works behind firewalls and NAT. Just curl -fsS -X POST <url>.
