bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal

  • Gives teams a self-hosted alternative to hosted uptime services, keeping monitoring data on their own infrastructure.
  • Covers HTTP, ping, port, SSL certificate, Docker, page speed, and game server checks plus optional CPU, RAM, disk, and network metrics, so one tool watches both endpoints and hardware.
  • Sends alerts through email, webhooks, Slack, Discord, PagerDuty, Telegram, Microsoft Teams, Matrix, Pushover, and Twilio SMS, and adds status pages, incident tracking, and scheduled maintenance windows.

under the hood

  • A React and Material-UI frontend talks to a Node.js backend, with MongoDB for storage and Redis for caching.
  • Remote hardware metrics come from an optional agent called Capture, written in Go and run on Linux, Windows, macOS, or Raspberry Pi.
  • Ships as Docker and supports Kubernetes via Helm charts, plus Coolify, Elestio, and Pikapods, and includes 16 language translations and configurable status page themes.
