Cronitor вырос из cron job monitoring — dead man's switch для scheduled tasks. Со временем добавил uptime checks и status pages. AtomPing — uptime monitoring first: 9 типов проверок, мультирегиональная архитектура, incident detection. С heartbeat monitoring для cron jobs в комплекте.
Пересечение функций значительное, но корни разные — и это определяет, где каждый инструмент сильнее.
Cron Job Monitoring
Cronitor: Родная территория. Cron expression parsing (валидирует `* */5 * * *`), expected runtime tracking, alert если job дольше обычного, job dependency chains, окружения (staging/prod), CI/CD integration. Глубокий tooling для scheduled tasks.
AtomPing: Heartbeat monitoring — job пингует URL после завершения, AtomPing алертит если ping не пришёл вовремя. Покрывает основной use case (пропущенный / зависший job), но без cron-specific features.
Для команды, у которой 50 cron jobs с зависимостями — Cronitor предоставит больше контроля. Для команды с 5-10 jobs, которой достаточно "алерт если job не отработал" — AtomPing's heartbeat monitoring хватит.
Uptime Monitoring
Check types: AtomPing — 9 (HTTP, TCP, DNS, SSL, ICMP, Keyword, Heartbeat, PageSpeed, AI). Cronitor — 2 (HTTP, Heartbeat).
Check interval: AtomPing — от 30 сек. Cronitor — от 30 сек (на верхних планах).
Regions: AtomPing — 11 EU-агентов с quorum confirmation. Cronitor — 4-6 global.
Response validation: AtomPing — JSON path, headers, regex, status codes. Cronitor — status code.
False alarm prevention: AtomPing — quorum + batch anomaly. Cronitor — retry from different location.
Uptime monitoring у Cronitor — add-on, не core product. Нет DNS monitoring, нет SSL expiry alerts, нет TCP port checks, нет keyword monitoring. Для серьёзного synthetic monitoring — AtomPing значительно сильнее.
Status Pages
AtomPing: Полноценные status pages: custom domain, компоненты, incident timeline, uptime metrics, edge infrastructure.
Cronitor: Status pages включены, но с ограниченной кастомизацией. Custom domain на платных планах. Меньше flexibility в оформлении.
Pricing
AtomPing: Free (50 мониторов) → Pro $5/мес (unlimited) → Business $27/мес
Cronitor: Free (5 monitors) → Starter $20/мес (15) → Plus $48/мес (50) → Pro $120/мес (200)
AtomPing's free tier: 50 мониторов. Cronitor's: 5. Cronitor Plus за $48 даёт 50 мониторов — AtomPing даёт столько же бесплатно. Для unlimited мониторов: AtomPing $5 vs Cronitor не предлагает unlimited опции.
Когда выбрать AtomPing
Uptime monitoring — основная задача (websites, APIs, infrastructure)
Нужен мониторинг API с response validation
Heartbeat для cron jobs достаточно (без cron expression features)
Бюджет: $0-27 vs $20-120/мес
Нужны диагностические инструменты
Когда выбрать Cronitor
Cron job monitoring — 80%+ вашей задачи
Нужны cron expression parsing, runtime tracking, job chains
Kubernetes job monitoring — core requirement
Verdict
Cronitor силён в cron-специфичных сценариях. AtomPing силён во всём остальном: uptime monitoring, false alarm prevention, status pages, diagnostic tools, и pricing. Если ваши cron jobs — главная головная боль, Cronitor оправдан. Для всех остальных задач мониторинга — AtomPing предоставляет больше за меньшие деньги.
FAQ
What is Cronitor?
Cronitor is a monitoring platform originally built for cron job monitoring (dead man's switch / heartbeat). Over time it expanded to include uptime monitoring, status pages, and Kubernetes job monitoring. It's popular among DevOps teams who primarily need to track scheduled tasks.
How does Cronitor compare for cron job monitoring?
Cronitor was built specifically for cron monitoring and has deeper features in this area: cron expression parsing, expected runtime tracking, job dependency chains, and CI/CD integration. AtomPing's heartbeat monitoring covers the core use case (alert if job doesn't ping within expected interval) but without cron-specific features like expression validation.
Does Cronitor have good uptime monitoring?
Cronitor added uptime monitoring later, and it's functional but not its strength. HTTP checks from multiple locations with basic alerting. No DNS monitoring, no TCP port checks, no SSL expiry alerts, no keyword monitoring, no quorum confirmation. For uptime monitoring specifically, AtomPing is significantly more capable.
How does pricing compare?
Cronitor free: 5 monitors. Starter: $20/month for 15 monitors. Plus: $48/month for 50 monitors. Pro: $120/month for 200 monitors. AtomPing free: 50 monitors. Pro: $5/month unlimited. AtomPing is 4-24x cheaper per monitor on paid plans.
Can I use AtomPing for cron job monitoring?
Yes. AtomPing's heartbeat monitoring works the same way: your cron job sends an HTTP request to a unique AtomPing URL after completion. If the request doesn't arrive within the expected interval, you get an alert. It covers the most important use case — detecting missed or failed jobs.
Which should I choose for mixed monitoring (uptime + cron)?
If cron monitoring is 80%+ of your needs and you need features like cron expression parsing and job chains — Cronitor. If uptime monitoring is your primary need and you also want heartbeat checks for cron jobs — AtomPing gives you both in one tool with better uptime monitoring and lower price.
