NetCrunch is commercial, self-hosted, agentless network and IT infrastructure monitoring software for Windows Server. It monitors network devices, servers, virtualization platforms, cloud services, applications, websites, logs, telemetry, and network traffic across on-premises and hybrid IT environments. Network traffic analysis supports NetFlow, sFlow, IPFIX, and other flow technologies.
NetCrunch supports 680+ monitoring targets and provides 270+ ready-to-use Monitoring Packs for devices, applications, and operating systems. Licensing is based on monitored nodes and network interfaces rather than individual sensors, checks, or metrics.
Real-time dashboards, policy-based monitoring, advanced alerting, and 40+ automated response actions—including remote script execution, service restart, process termination, and device reboot—support centralized monitoring and automated remediation.
NetCrunch runs on Windows Server and can monitor infrastructure deployed on-premises, in the cloud, or across hybrid environments.

UptimeRobot is a website monitoring service with a forever free plan that lets you register with just an email and monitor up to 50 websites, servers, or keywords with 5-minute intervals. Setup takes only a few clicks.
For faster checks and advanced features, paid plans offer 1-minute or 30-second intervals, along with SSL certificate, domain expiry, and heartbeat (cron job) monitoring. You can also create up to 100 status pages, customize them to match your brand, protect them with a password, and allow subscribers to receive updates.
Get notified instantly via email, SMS, voice calls, or integrations with Slack, Zapier, PagerDuty, Splunk On-Call, Telegram, Webhooks, Discord, Mattermost, Pushbullet, Microsoft Teams, Google Chat, Pushover, and more. Mobile push notifications are available through the iOS and Android apps.
Other features include maintenance windows, incident tracking with root cause analysis, tags, comments, and filters. Share account with other team members.

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.
