Cronitor
What it is
Cronitor is a freemium monitoring service for cron jobs, background workers, scheduled agent tasks, websites, APIs, and heartbeats. Job monitoring retains each run’s status, metrics, and output to help investigate failures and delays. Website and API checks run from 12 or more worldwide locations and examine availability, content, performance, and certificates. Heartbeat monitors can alert when expected activity from agents, queues, devices, or other systems stops. Monitors can feed public or private status pages, while a lightweight cookie-free script tracks 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. The free Hacker plan costs nothing and includes five monitors, email and Slack alerts, one status page, 50 subscribers, and five-minute fastest checks. Business costs $2 a month per monitor plus $5/mo per user. Enterprise starts at $6,000 a year.
