Overmonitor is a cloud-based infrastructure, website, and endpoint monitoring platform built for fast setup without enterprise complexity. Monitor websites, APIs, servers, processes, Windows services, event logs, performance counters, SNMP data, uptime, response time, DNS, SSL certificates, internal endpoints, and network health from one dashboard. The lightweight 2.1 MB agent runs as an idle process, requires no inbound firewall exceptions or open ports, and sends a secure heartbeat every minute. Configure monitoring quickly through the web interface and target checks by city-level geography. Maintenance windows suppress expected noise, while configurable alerts, push notifications, and audible dashboards keep the right people informed. Multi-location endpoint checks validate incidents, reduce false alarms, expose regional problems, and reveal how availability and responsiveness differ across target markets. Distributed Monitors expand Overmonitor’s network by allowing eligible servers to opt in and check up to 10 external endpoints. Checks add negligible data to the existing heartbeat, require no extra configuration or firewall changes, execute no remote web scripts, and store no monitored data on the server. If a participating server or network becomes unavailable, its checks are automatically reassigned. Participation also earns prorated invoice credits. Trend Analysis turns historical infrastructure metrics into proactive capacity planning. Choose from thousands of performance counters, including CPU utilization, available memory, and disk space, then assign minimum and maximum thresholds. Once enough data has been collected, Overmonitor applies linear regression to estimate when a metric may cross its limits. A configurable planning horizon controls when responsible team members are alerted, helping you rebalance workloads, tune resources, or scale capacity before performance becomes an outage or unbudgeted emergency. Trend Analysis is included with every server metric at no additional charge. Overmonitor also includes process rollups, embeddable performance graphs, endpoint health visibility, flexible retention, multiple users with roles, and à la carte pricing so you pay only for the monitoring you need. Detect outages, correlate website symptoms with server health, analyze performance, track availability, and improve end-user experience before small issues become downtime.

SuperOps is the AI-native unified platform for modern MSPs and internal IT teams. It replaces the typical four-to-six-tool IT operations stack - PSA, RMM, helpdesk, MDM, asset tracking, network monitoring, patch management and IT documentation - with a single, built-as-one platform on a shared data layer. That architectural choice is what makes the rest of the platform work, particularly its agentic AI. Monica AI, SuperOps' intelligence layer, was designed alongside the platform from day one. It triages tickets, surfaces patch and CVE risks, drafts worklogs, suggests knowledge base articles, and increasingly handles fully autonomous workflows for routine work. SuperOps supports Windows, macOS, Linux, iOS, iPadOS and Android, integrates with the IT and MSP ecosystem (Slack, Teams, Azure AD, Okta, QuickBooks, Xero, Bitdefender, SentinelOne and more), and bundles Splashtop and ISL Online remote access free. Transparent pricing, fast deployment, founder-led product investment.
