Judgement

What it is

Complete system

What it does

A desktop SSH client with saved hosts, split terminals, an SFTP browser and a built-in AI agent that can run commands on your servers.

Adopt it when

You manage several servers and want an open-source alternative to Termius with SFTP and AI help in one app.

Watch out

It is under a year old, built on Electron, and letting an AI agent run commands on production hosts carries real risk.
