How it works

Dead simple to integrate

Add CronGuard to any cron job in under 60 seconds. No SDK, no agent, no config files — just HTTP.

01 / CREATE

Create a monitor

Name your job, set how often it runs, and choose where to send alerts. You get a unique ping URL.

POST /monitors → { "ping_url": "https://..." }
02 / INTEGRATE

Ping after each run

Append one line to your cron script — a simple GET or POST. No authentication, no headers required.

#!/bin/bash ./run-backup.sh curl -s https://cg.dev/ping/abc123
03 / ALERT

Get alerted instantly

Miss a ping and we notify you within 5 minutes. Email, Slack, or webhook — your choice.

Why CronGuard

Built for production jobs

Not a side-project toy. CronGuard runs on Cloudflare's global network — no single region, no cold starts, no downtime.

5-minute check intervals

Checks run every 5 minutes on Cloudflare's edge. You'll know within minutes when a job stops.

Full ping history

Every check-in is logged. View your job's uptime history, last ping time, and alert history.

Grace periods

Jobs that occasionally run long won't false-alarm. Configure a grace window per monitor.

Multi-channel alerts

Route alerts to email, Slack, or any webhook. Different channels per monitor on Pro.

CF Cron auto-detection

Cloudflare Workers users get automatic cron trigger detection — no manual URL setup required.

No agent required

A plain HTTPS call. Works with any language, any scheduler, any platform. If it can curl, it works.

Simple, honest pricing

Pay for monitors, not pings. No usage-based surprises.
