Beszel is a lightweight server monitoring platform that provides system metrics, Docker statistics, and configurable alerts through a web interface.

The tool addresses the need for resource-efficient server monitoring by combining a hub component built on PocketBase with distributed agents that collect and report metrics from monitored systems. It tracks CPU, memory, disk, network, temperature, and container usage, storing historical data for trend analysis. The agent-based architecture allows monitoring of multiple systems from a central dashboard while keeping resource overhead minimal compared to heavier alternatives.

Beszel suits self-hosted environments and homelab setups where simplicity and low overhead matter. It works well for users who need Docker or Podman container monitoring alongside host system metrics, and for those running ZFS storage who want pool health and per-dataset usage tracking. The platform supports multi-user access with OAuth and OIDC authentication, making it suitable for shared infrastructure where different users manage their own systems. Administrators can share systems across users and configure alerts for CPU, memory, disk, bandwidth, temperature, fan speed, load average, and system status. Automatic backups to disk or S3-compatible storage provide data protection without manual intervention.

The project shows consistent maintenance with regular responses to issues and discussions, though the maintainer notes that response time may vary. Development activity includes ongoing bug fixes and feature additions based on user feedback. The codebase is actively refined to maintain the lightweight character that distinguishes the tool from heavier monitoring solutions.
