Cron job & heartbeat monitoring for scheduled jobs and Kubernetes CronJobs. Get alerted when a job stops checking in — not website uptime. Free Tier is free forever.
Unlike uptime monitors that only check if your site is up, Seiri watches whether your actual jobs ran — cron, Kubernetes CronJobs, and webhooks alike. Set up in minutes, alerts via Slack, Discord, Telegram, Email, or SMS.
