What it is
Checkmate is a free, open-source, self-hosted dashboard for monitoring infrastructure, service uptime, PageSpeed, and incidents. It checks HTTP, ping, TCP, gRPC, WebSocket, DNS, SSL, and more than 100 game server types. Its Capture agent reports server CPU, memory, disk, temperature, and network metrics, while PageSpeed monitoring tracks Lighthouse scores and Core Web Vitals over time. Public status dashboards can show service uptime and incident history with custom branding. Alerts can go through email, Slack, Discord, Telegram, Twilio SMS, Pushover, ntfy, Matrix, Rocket.Chat, PagerDuty, Microsoft Teams, and webhooks. The operator configures the database where metrics, logs, incidents, and user accounts are stored; the maker says there is no phone-home or telemetry pipeline. Checkmate uses the AGPL-3.0 license and supports Docker Compose and Kubernetes/Helm deployment. Its image runs on x86, Apple Silicon, and Raspberry Pi. The free plan lists all features, no monitor limits, self-hosting, and 12 alert channels.
