## What it is
Checkmate is an open-source, self-hosted infrastructure and uptime monitoring platform by Bluewave Labs. It tracks server hardware, uptime, response times, SSL certificates, Docker containers, and incidents in real time with visual dashboards, multi-channel alerts, and public status pages.

## Use cases
- monitor website uptime and get alerts when it goes down
- self-hosted alternative to UptimeRobot
- track CPU, memory, and disk usage across my servers
- monitor Docker container health and restarts
- get notified before SSL certificates expire
- create a public status page for my services
- check page speed and Core Web Vitals over time
- send downtime alerts to Slack, Discord, or Telegram

## When to choose
- you want a single self-hosted dashboard for uptime, infrastructure, and Docker monitoring without per-host pricing
- you need quick setup with built-in alerting and status pages instead of assembling Prometheus, Grafana, and Alertmanager
- your telemetry must stay inside your own infrastructure
- you want many monitor types (HTTP, ping, TCP, gRPC, DNS, WebSocket, SSL, PageSpeed) in one tool

## When to avoid
- you need deep APM, tracing, or application-level metrics beyond uptime and hardware
- you already have a mature Prometheus/Grafana stack with custom exporters
- you require a managed SaaS service with no self-hosting overhead
- you need a permissive license for embedding, since Checkmate is AGPL-3.0
