Local appliance
A free Docker appliance for local-first network telemetry.
The Infracheck Appliance runs inside the customer network and gives technicians local evidence for WAN, DNS, HTTP/TLS, packet loss, LAN inventory, alerts, and reports.
What the appliance monitors
- Gateway reachability, packet loss, jitter, and latency.
- WAN download/upload quality and baseline changes.
- DNS lookup health, resolver status, and external HTTP/TLS checks.
- LAN discovery, new devices, missing devices, hostname overrides, and notes.
- Health score, active alerts, triage hints, and PDF reports.
Deployment model
The appliance is published as a free GitHub repository and runs with Docker Compose on a Linux host. It stores data locally by default and can be paired with the Android app.
git clone https://github.com/gatgserv/infracheck-appliance.git
cd infracheck-appliance
sh scripts/install-linux.shWhy local-first matters
Customer network faults are often visible only from inside the LAN. A local appliance can see symptoms that remote cloud checks may miss, especially DNS, gateway, LAN inventory, and local service behavior.
