HeyOnCall combines website/API monitoring, heartbeat/cron monitoring, SSL checks, incident management, on‑call schedules, escalations, alert delivery, and mobile app alerting into one integrated product.
HeyOnCall is built for small engineering teams and solo founders who want reliable paging, simple setup, and fewer moving parts.
Get impossible-to-ignore Critical Alerts that bypass Do Not Disturb, plus Slack, email, webhooks, and more. HeyOnCall is designed from the ground up to reduce false positive alerts (getting alerted when your site is actually up) and false negatives (missing an outage due to broken monitoring or alerting).
