What Cronitor is
Cronitor monitors scheduled work and service health, covering cron jobs, background workers, scheduled agent tasks, websites, APIs, and heartbeats. Job monitoring retains each run’s status, metrics, and output to help investigate delays and failures. Website and API checks run from 12+ worldwide locations and can examine availability, content, performance, and certificates. Heartbeats can trigger alerts when expected activity from agents, queues, devices, or other systems stops. Monitors can connect to public or private status pages, and a lightweight cookie-free script tracks web traffic, errors, and performance. Alert integrations include Slack, Microsoft Teams, Discord, Google Chat, Telegram, Lark, PagerDuty, Datadog On-Call, OpsGenie, Splunk On-Call, and webhooks. Cronitor is listed for API, Linux, and web. The free Hacker plan includes five monitors, email and Slack alerts, one status page, and 50 subscribers, with a five-minute fastest check frequency; it excludes SMS alerts and premium integrations. Business costs $2/mo per monitor plus $5/mo per user. A 14-day trial is available.
