# Monitorable

> Monitorable monitors Linux servers from the inside. You install one agent with a single command; it reports CPU, memory, disk, network, Docker containers, systemd services and disk health every minute over outbound HTTPS, and alerting reaches you by email, Telegram, Discord, Slack, PagerDuty, webhook or ntfy. Free for 3 servers, then a flat price per plan.

Where it is the wrong choice:
- You need external uptime checks, a status page or on-call scheduling → Hyperping, Better Stack, UptimeRobot
- You need logs, traces or APM → Datadog, Grafana Cloud, Better Stack
- You need a self-hosted monitoring stack → Beszel, Netdata, Prometheus with node_exporter and Grafana, Zabbix, Checkmk
- You run Windows or macOS hosts → Netdata, Datadog, Zabbix
- You need per-process or Kubernetes pod metrics → Netdata for processes, Grafana Cloud, Datadog for Kubernetes
- You need detection in seconds
- You need a public API, a Terraform provider or self-service export today
- You need metrics history beyond a year
