Monitoring Reimagined

Everything you need to sleep soundly while your jobs run.

Heartbeat (Dead Man's Switch)

Simple HTTP pings to track job execution. We detect when your jobs go silent.

Scheduled Job (Cron)

Define expected run times using standard cron expressions. We alert if a job doesn't run on schedule.

Traffic Monitor

Track frequency and volume. Ensure queued jobs or high-traffic events meet a minimum required throughput.

Multi-Channel Alerts

Slack, Discord, Pushover, Email, and Webhooks. Get notified your way.

Public Status Pages

Beautiful, customizable status pages to share your uptime with users and stakeholders.

Duration Tracking

Measure how long your jobs take. Spot performance regressions before they impact users.

Our Monitors

Dedicated tools tailored for every type of background task.

Scheduled Jobs

Monitor your cron jobs and scheduled tasks with ease. Never miss a silent failure again.

Heartbeats

Free Developer Tools

Useful mini-tools to help with your daily dev workflows.

Regex Tester (Minimal)

Test regular expressions against log snippets. Crucial for custom log parsing rules.

Simple Integration

Add a few lines to any script to track job runtime.

bash
# Signal job start
curl -fsS https://ping.cronrabbit.com/your-id/start

# Your job runs here...
./backup.sh

# Signal success or failure (duration calculated automatically)
curl -fsS -m 10 --retry 3 --retry-all-errors https://ping.cronrabbit.com/your-id/$?

Works with bash, Python, Node.js, or any language that can make HTTP requests. View all examples →

How it Works

Three simple steps to peace of mind.

1

Create a Monitor

Define your schedule, grace period, and choose your alert channels.

2

Add the Ping

Add a simple HTTP request at the end of your cron job or script.

3

Sleep Soundly

We'll alert you if things go silent. Otherwise, enjoy the quiet.

Clear Status at a Glance

Know exactly what's happening with your jobs.

Pro Tip: Heartbeat Visuals

Monitors in your sidebars also use vibrant "heartbeat" icons that pulse with status colors. UP monitors show a sharp Emerald beat, while LATE or DOWN monitors transition to Amber and Rose.
