What HeyOnCall is
HeyOnCall combines website and API checks with heartbeat and cron monitoring, SSL checks, incident management, on-call schedules, escalations and alert delivery. Website and API monitoring covers HTTP/HTTPS uptime and performance, response assertions, redirects, and request and response inspection. SSL checks validate certificates and chains and can warn before expiration. Teams can create timezone-aware rotations, adjust or trade shifts, and sync calendars with Google Calendar, Outlook, and iCalendar feeds. Unacknowledged incidents can escalate to another user, a rotation, or everyone in a rotation. Critical Alerts on iOS and Android can bypass Do Not Disturb, silent or vibrate modes, and volume settings, repeating until acknowledged. Alert sources include Datadog, Prometheus Alertmanager, Uptime Kuma, and webhook-capable tools; channels include Slack, email, Telegram, and webhooks. Its API supports custom triggers, incident resolution, and custom payloads. The Free Trial for evaluating is free and limited to 10 users, with fewer triggers and HEAD requests only. Solo costs $3 a month; Pro costs $32 a month.
