Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions.

It has a friendly web interface, simple configuration, and is ready to use out of the box. It supports automatic backup, multi-user, OAuth authentication, and API access.

Features

• Lightweight: Smaller and less resource-intensive than leading solutions.
• Simple: Easy setup with little manual configuration required.
• Alerts: Configurable alerts for most metrics. Supports many notification services.
• Docker stats: Tracks CPU, memory, and network usage history for each container.
• Network monitoring: Monitor response time and interruptions directly from agents.
• S.M.A.R.T.: Disk health data and notifications on drive failure.
• Multi-user: Users manage their own systems. Admins can share systems across users.
• OAuth / OIDC: Supports many OAuth2 providers. Password auth can be disabled.
• Automatic backups: Save to and restore from disk or S3-compatible storage.

Architecture

Beszel consists of two main components: the hub and the agent.

• Hub: A web application built on PocketBase that provides a dashboard for viewing and managing connected systems.
• Agent: Runs on each system you want to monitor and communicates system metrics to the hub.

Getting started
