Beszel

Beszel is a lightweight, self-hosted server monitoring hub designed for homelabs and small to medium infrastructure. It collects historical metrics including CPU, memory, disk usage, network throughput, and Docker container statistics — all accessible from a clean web UI.

Unlike heavy enterprise monitoring solutions like Datadog or New Relic, Beszel keeps resource usage minimal. The hub and agent architecture means you deploy a small agent on each server you want to monitor, with all data flowing back to a central hub. Alerts can be configured to notify you via email or other channels when thresholds are breached.

Beszel is written in Go, ships as a single binary, and can be run via Docker. It stores data using SQLite, making it easy to set up without an external database. With over 20,000 GitHub stars, it has quickly become a favourite in the self-hosting community.
