Overmonitor
Overmonitor is cloud-based infrastructure, website, and endpoint monitoring built for teams that want fast setup, clear alerts, and practical visibility without the complexity or cost of enterprise monitoring suites. Monitor websites, servers, endpoints, processes, Windows services, event logs, uptime, response time, SSL certificates, and internal network health from one easy dashboard.
At the core of Overmonitor is a small, lightweight server agent that installs quickly, pairs with your account, and reports a heartbeat every minute from inside your network. This gives you visibility beyond public uptime checks, helping detect server outages, stalled services, failing processes, internal connectivity problems, and endpoint health issues before they become customer-facing downtime.
Overmonitor supports city-level geotargeted monitoring, practical maintenance windows that reduce alert noise, push notifications for alerts, audible dashboard alerts for operations screens, process monitor rollups, embeddable performance graphs, and flexible à la carte pricing so you only pay for the monitoring you need.
Designed for SaaS operators, IT teams, MSPs, developers, and small businesses, Overmonitor helps you track availability, analyze website performance, monitor infrastructure health, and improve end-user experience without being locked into a bloated monitoring platform.
