Monitor outages, latency, packet loss, DNS, Wi-Fi, and device health from where devices actually connect. Keep history and incident evidence so intermittent problems are easier to diagnose.
NetTact is network monitoring and diagnostics software for homes and small businesses. Agents measure from each device's network and push results to a self-hosted Server, keeping connection quality, service response, endpoint health, and fault evidence in one history.
Network quality
Track latency, packet loss, jitter, and gateway health, with available path diagnostics when a fault occurs.
Latency · packet loss · jitter · gateways · path diagnostics
Availability
Test DNS resolution, TCP connections, TLS handshakes, and HTTP responses to see where a service begins to fail.
DNS · TCP · TLS · HTTP
Endpoint health
Relate wireless signal, link rates, CPU, memory, disks, and network throughput to problems at the endpoint itself.
Wi-Fi · CPU · memory · disks · throughput
Diagnosis
Retain trends, incident evidence, path diagnostics, and recovery. When channels are configured, policies send fault and recovery notifications.
History · incidents · diagnosis · recovery · notifications
NetTact keeps the measurements that matter and connects anomalies, path diagnostics, incidents, and recovery. You see more than a red dot: you get a timeline you can inspect after the fact.
Measurement, history, incidents, and notifications form one troubleshooting path instead of leaving isolated numbers across separate tools.
Agents run probes where Windows, Linux, macOS, Docker, and OpenWrt devices actually connect, capturing the network their users experience.
The server stores metrics and state centrally so brief fluctuations, gradual degradation, and recovery remain visible on a timeline.
Built-in detection records confirmed faults as incidents and connects available metrics, endpoint state, and path diagnostics to narrow the investigation.
When channels are configured, monitoring-group policies send fault and recovery notifications. Incidents remain fully recorded without a channel.
The same target can look completely different from another location. NetTact moves observation to devices on the networks people use, then brings the results together.
Weak Wi-Fi, a bad gateway, DNS trouble, or one remote site with a poor uplink is not hidden behind the server's single point of view.
The server never initiates a connection to an Agent, and Agents need no inbound ports. They work behind NAT, firewalls, and dynamic IPs as long as each Agent can reach its Server.
The self-hosted server stores configuration, metrics, and incidents, while collection permissions and probe-target access remain explicitly controlled.
Try NetTact on one computer, or deploy an always-on monitor for multiple devices and locations.
