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>.
