Cronitor
Monitoring made for developers
Cronitor is a monitoring platform covering cron jobs, agents, websites, APIs, heartbeats, and other scheduled or networked systems. It detects failures, late runs, downtime, performance issues, and SSL certificate problems, and sends alerts with context so teams can respond quickly.
The platform includes five modules: Jobs for cron and agent monitoring, Checks for uptime and performance testing from 12+ locations with content and certificate assertions, Heartbeats for systems without a checkable endpoint, Status Pages for public or private uptime communication, and Analytics for cookie-free traffic, error, and performance tracking. Alerts integrate with Slack, PagerDuty, Email, Discord, Opsgenie, SMS, Telegram, Splunk On-Call, Phone, Teams, Google Chat, and Webhook. It offers SDKs, APIs, an MCP server, and AI agent monitoring.
Cronitor is built for developers and teams managing reliability. Packaging includes a free Hacker plan with limited monitors, a Business plan with a 14-day trial billed by monitor and user count, and an Enterprise edition with custom features and invoice billing.
