Beszel

Beszel at a glance

Beszel is a lightweight open-source server-monitoring tool with a clean dashboard and history, a simple self-hosted alternative for keeping an eye on a handful of machines. Beszel ships regular releases plus fixes; as a monitoring tool with visibility into your systems, keeping it current and access-controlled matters.

For admins Beszel uses a hub-and-agent model: the hub presents the dashboard and the agents run on monitored machines — keep both current and compatible. The hub belongs behind authentication and off the open internet, since a monitoring dashboard reveals system detail. Updates run by swapping the binary/container; back up the configuration first. Its lightweight design makes it easy to run, but it's still a networked service to keep patched. After updating, verify that agents report and the dashboard shows data. It's aimed at small-scale monitoring; for large fleets, heavier platforms fit better. Track releases; patchletter surfaces new Beszel versions so fixes land.
