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.

While many uptime monitors simply verify server responses, upsonar takes it a step further by fully loading your webpage to identify all external components, including CDN-hosted assets, third-party scripts, web fonts, and API endpoints. Should any of these elements fail, you receive timely alerts, ensuring you can address issues before your users experience them.
Additionally, availability checks are performed from numerous locations worldwide simultaneously, which helps ensure that any regional CDN failures or localized outages do not go unnoticed. In addition to monitoring uptime, upsonar keeps an eye on SSL certificates nearing expiration, tracks the expiration dates of domains to avoid renewal issues, and identifies changes in DNS records that could signal unauthorized alterations.
The five types of monitoring operate cohesively within a single dashboard, offering you a streamlined overview. Notifications can be sent via email, Telegram, or through webhooks that integrate seamlessly with platforms like Slack, Discord, and PagerDuty. You can begin with a free plan that allows monitoring of three websites, complete with all features and no credit card required, making it easy to experience the full benefits without commitment.
