About crond.io

crond.io is a cron job monitoring platform built for developers and ops teams. We help you know instantly when your scheduled tasks fail, run late, or stop running entirely.

The problem

Cron jobs are invisible by default. They run in the background, and when they fail, nobody notices — until a database backup is missing, an ETL pipeline goes stale, or a cleanup script stops running. By then, you're already debugging in production.

The standard advice — “just check the logs” — assumes you remember to look. In practice, the same systems that need monitoring most are the ones nobody thinks about for weeks at a time. We've all watched a 6-month-old failure surface because someone finally read a Slack channel.

Our approach

We built crond.io around heartbeat monitoring: your cron jobs ping us on every successful run. If we don't hear back within the expected window plus a grace period, we alert you via email or webhook (which fans out to Slack, PagerDuty, Discord, Opsgenie, Teams, or anything else that accepts an HTTP request).

Our lightweight CLI agent wraps any command and automatically reports exit codes, execution duration, and captured output — no code changes required. One line in your crontab and you're monitored.

Open source

The crond-agent CLI is fully open source. We believe monitoring infrastructure should be transparent and auditable: you can inspect exactly what data the agent sends, build it yourself, and contribute improvements. The agent is a single static Go binary with no runtime dependencies.

How we're different

The cron-monitoring space isn't empty — Healthchecks.io, Cronitor, UptimeRobot, and Better Uptime all do this. We chose to build crond.io because we wanted three things at once that no single product offered: a real CLI agent (not just a ping URL), first-class Kubernetes support (Helm chart, no operator), and an open-source monitoring path. If you only need ping URLs, Healthchecks.io is excellent — and we say so on each comparison page.

What we won't do

We won't sell your monitoring data, enroll you in marketing email lists by default, or hide pricing behind a sales call. The Free tier is genuinely free forever — not a 14-day trial with a credit card.
