Cronitor

What Cronitor is

Cronitor monitors cron jobs, background workers, scheduled agent tasks, websites, APIs, and heartbeats. Job monitoring retains status, metrics, and output from each run to help investigate failures and delays. Website and API checks run from 12+ worldwide locations and can test availability, content, performance, and certificates. Heartbeat monitoring can alert when expected activity from agents, queues, devices, or other systems stops. Monitors can feed public or private status pages, and a lightweight cookie-free script tracks web traffic, errors, and performance. Listed 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 platforms. Its Hacker plan costs nothing and includes five monitors, email and Slack alerts, one status page, 50 included subscribers, and a fastest check frequency of five minutes; it excludes SMS alerts and premium integrations. Business costs $2 a month per monitor plus $5 a month per user, billed monthly with no contract. A 14-day trial is listed.
