What is Beszel?

Introduction

Beszel is a lightweight server monitoring platform that provides a friendly, configurable interface for tracking system health and Docker statistics. It supports historical data storage, alerting, and simple setup processes. It offers multi-user support, OAuth / OIDC authentication, automatic backups, and more—making it ready to use out of the box.

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, creating a minimal SSH server to communicate system metrics to the hub.
