HeyOnCall provides a unified SaaS platform that combines website, API, SSL, and cron‑job monitoring with on‑call rotation, escalation, and multi‑channel alert delivery. Teams can define health checks, integrate third‑party APM alerts, and automatically route critical incidents to the right engineers via mobile app, Slack, Telegram or email, reducing configuration overhead and missed alerts.

Problem
Small engineering teams and solo developers often need to monitor website uptime, API health, SSL certificates, and cron job heartbeats while also managing on‑call schedules and alert escalation. Existing solutions typically require separate tools for monitoring and paging, leading to fragile integrations, configuration overhead, and missed or noisy alerts.
Solution
HeyOnCall combines external monitoring (HTTP/HTTPS checks, SSL validation, cron‑job heartbeats, and third‑party integrations such as Prometheus, Datadog, and Uptime Kuma) with built‑in on‑call rotation, escalation, and multi‑channel alert delivery. Users define triggers, set alerting criteria, and receive critical alerts via the HeyOnCall mobile app, Slack, Telegram, or email. Alerts can be marked as acknowledged to stop further notifications, and triggers automatically resolve when the monitored service recovers. The platform includes business‑hour schedules, false‑positive reduction settings, and escalation rules to ensure only actionable incidents reach on‑call engineers. All monitoring and paging functions are delivered from a single, reliable SaaS product, eliminating the need for multiple point solutions.
Target Audience
HeyOnCall is aimed at small DevOps, SRE, and engineering teams as well as solo founders who need a unified monitoring and paging solution without extensive configuration overhead.
