Free Cron Tools vs Cronhub and Cronitor — Stop Paying for the Wrong Thing
Table of Contents
Cronhub charges $10-25/month. Cronitor starts at $29/month. If you've been paying for either service just to build and validate cron expressions, you've been paying for the wrong product. Our free cron generator and crontab visualizer cover expression work entirely — no account, no subscription, no limits.
This guide explains exactly what paid cron services actually do, what they don't do, and when (if ever) you need one.
What Paid Cron Services Actually Sell
Cronhub and Cronitor are cron job monitoring services, not expression tools. Their core product is dead man's switch monitoring:
- Your job pings their server with a URL on success
- If the ping doesn't arrive within the expected window, they alert you (email, Slack, PagerDuty)
- Dashboard showing job run history, success/failure rates, duration trends
That's what you pay for. The cron expression generator they include in the UI is a convenience feature — it's not the product.
Cronhub pricing (as of 2026): Free tier (5 monitors), Starter $10/mo (25 monitors), Growth $25/mo (100 monitors).
Cronitor pricing: Free tier (5 monitors), Developer $29/mo (50 monitors), Team $79/mo.
If you signed up for either service to get access to their expression generator, you were solving the wrong problem. The expression generator is free everywhere — the monitoring is what costs money.
Feature-by-Feature: Free vs Paid
| Feature | Free (WildandFree Tools) | Paid (Cronhub/Cronitor) |
|---|---|---|
| Build cron expressions | Yes — visual builder + text input | Yes — included but secondary |
| Translate expression to English | Yes — instant, browser-side | Yes |
| See next N run times | Yes — next 20 on calendar | Yes |
| Validate syntax | Yes | Yes |
| Alert when job fails | No | Yes — core product |
| Alert when job misses schedule | No | Yes — core product |
| Job run history dashboard | No | Yes |
| Slack/PagerDuty integrations | No | Yes |
| Execution duration tracking | No | Yes |
| Requires account/signup | No | Yes |
| Cost | $0 | $10-79/mo |
The dividing line is clear: expression work is free everywhere. Execution monitoring costs money.

Pay for monitoring when you have a specific failure scenario that costs real money if missed:
- Your nightly backup job didn't run and you didn't notice for a week. This is exactly what monitoring services prevent.
- Your billing/invoicing job silently failed and customers weren't charged. Dead man's switch catches this; log tailing doesn't.
- You have 50+ production cron jobs and can't manually watch logs for all of them. A monitoring dashboard that shows green/red for every job is worth the subscription.
- You need compliance audit trails — proof that job X ran every day for the past 90 days.
Before paying, consider Healthchecks.io — free tier includes 20 monitors, which covers most small teams. The paid plans start at $20/mo if you exceed 20 checks. This is a meaningful alternative to Cronhub/Cronitor if your monitoring needs are modest.
The Complete Free Stack for Cron Expression Work
For expression building and validation, this workflow replaces everything a paid service offers in its expression tools — at $0/mo, forever:
- Build: Free Cron Generator — visual dropdowns + advanced text mode + quick presets
- Verify: Free Crontab Visualizer — next 20 runs on a calendar in your local timezone
- Timezone check: Free Timestamp Converter — convert any time between UTC and local zones
- Translate: Same visualizer — paste any expression and get instant plain-English description
If you currently have a Cronhub or Cronitor subscription and you're only using it for the expression generator — cancel it. Use these tools instead. If you're using it for monitoring and alerting, keep it — that's the service you're actually buying, and the free expression tools don't replace it.

Open Free Crontab VisualizerFrequently Asked Questions
Is there a completely free alternative to Cronhub for cron expression building?
Yes. The WildandFree free cron generator at /developer-tools/cron-generator/ builds cron expressions with visual dropdowns and shows next run times — no signup, no subscription, no rate limits. It covers 100% of what Cronhub's expression builder does. What it doesn't replace is Cronhub's monitoring feature (alerting when jobs fail or miss their schedule), which is a separate and genuinely paid-worthy capability.
What is the cheapest way to monitor cron jobs in production?
Healthchecks.io has a genuinely free tier covering up to 20 monitors with email and Slack notifications. For most individual developers and small teams, this covers all monitoring needs at $0/mo. Upgrade to their $20/mo paid plan only if you exceed 20 checks. This is cheaper than both Cronhub ($10/mo) and Cronitor ($29/mo) for comparable monitoring capabilities.
Can I build and test cron expressions without creating a Cronhub account?
Yes. The WildandFree cron generator and crontab visualizer require no account. Open them in any browser, build your expression, and see next run times immediately. No email address, no trial period, no credit card. Both tools run entirely in your browser and work offline after the initial page load.
