Summary

Checkmate is a free, open-source, self-hosted dashboard for infrastructure monitoring, uptime, PageSpeed, and incident alerts. 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. PageSpeed monitoring tracks Lighthouse scores and Core Web Vitals over time, while public status dashboards can show per-service uptime, incident history, and custom branding. Alerts can go to email, Slack, Discord, Telegram, Twilio SMS, Pushover, ntfy, Matrix, Rocket.Chat, PagerDuty, Microsoft Teams, and webhooks. The operator's configured database stores metrics, logs, incidents, and user accounts; 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. The image runs on x86, Apple Silicon, and Raspberry Pi. The free plan includes all features, no monitor limits, self-hosting, and 12 alert channels.
