Better Stack vs Healthchecks.io for cron job monitoring

Better Stack and Healthchecks.io are both used for cron job monitoring, but they come from completely different directions. Healthchecks.io was built specifically and exclusively for heartbeat monitoring. Better Stack started as an uptime monitoring platform and added heartbeat monitoring as one component of a broader observability offering.

That difference in origin shapes everything: what each tool catches, how it's priced, and what kind of team it's built for.

Healthchecks.io: focused, free, and open source

Healthchecks.io does one thing: it monitors whether your scheduled jobs check in on time. Each check gets a unique ping URL. Your job hits that URL on completion. If Healthchecks.io doesn't receive a ping within the expected window, it sends an alert.

It also supports start pings for hung job detection, cron expression parsing for schedule-aware timing, and a wide range of alert integrations — Slack, Discord, PagerDuty, email, webhooks, Telegram, and more.

The free hosted tier includes 20 checks and three months of log history. The codebase is BSD-licensed and self-hostable, which is a meaningful advantage for teams with data sovereignty requirements or infrastructure preferences.

What it doesn't do: no log attachment on failure, no alert rules on job output metadata, no duration anomaly detection, no uptime monitoring for HTTP endpoints. It monitors execution, not outcomes. If your job exits 0 and processes nothing, Healthchecks.io sees a successful ping.

Pricing: Free for 20 checks. Paid plans from $5–$80/month.

Better Stack: observability platform with heartbeat monitoring included

Better Stack is a broader platform covering uptime monitoring, log management, incident response, and on-call scheduling. Heartbeat monitoring — the equivalent of what Healthchecks.io does — is one feature within a larger product.

The advantage: if your team already uses Better Stack for uptime monitoring or logging, adding cron job heartbeats doesn't require a separate tool. When a cron job fails, you can jump straight from the alert to the relevant log lines in the same interface.

What it does well: tight integration between heartbeat alerts and log management makes root cause analysis faster. The on-call scheduling and incident management features are mature. The UI is polished.

What it doesn't do: no alert rules on job output metadata. A job that exits 0 after processing zero records appears healthy. No duration anomaly detection either.

Pricing: Heartbeat monitoring is included in paid plans. Pricing is modular and scales with the number of monitors and team members. More expensive than Healthchecks.io for teams that only need heartbeat monitoring, but comparable if you're already paying for uptime monitoring anyway.

Where both tools fall short

Both Healthchecks.io and Better Stack share the same fundamental limitation: they monitor whether a job ran, not what the job accomplished.

A nightly sync job that processes zero records sends its ping on time. Both tools record the run as successful. The sync failure is invisible until something downstream breaks — stale data, a missing report, an unfilled queue.

Detecting this class of failure requires alert rules on job output metadata: your job reports what it actually did (records synced, API calls made, rows processed), and you define rules that fire when those values fall outside expected ranges.

Crontify adds this on top of standard missed run and hung job detection. When a job calls success(), it attaches a metadata object:

await monitor.success({
  meta: {
    records_synced: result.count,
    api_calls_made: result.apiCalls,
  }
});

You then define rules in the dashboard: records_synced eq 0 → fire alert. The job is still logged as a success — but you get an immediate notification when it produces no output.

Which one to choose

Choose Healthchecks.io if:

• You need pure heartbeat monitoring with no other requirements
• The 20-monitor free tier covers your needs
• Self-hosting matters to your team
• You want the simplest possible setup

Choose Better Stack if:

• You're already using or evaluating Better Stack for uptime monitoring or logging
• You want one platform for multiple observability needs
• On-call scheduling and incident management are requirements

Choose Crontify if:

• Your jobs process data and exit code 0 is not a sufficient signal
• You want alert rules on job output metadata — the one feature neither Healthchecks.io nor Better Stack offers
• You want log output delivered inline in the Slack alert rather than requiring a separate log platform to diagnose failures

Crontify is free to start — 5 monitors, no credit card required.
