User Guide

Termalith keeps your servers, network devices and remote desktops in one window: saved sessions on the left, tabs on the right. It is free and open source (MIT) and works the same on macOS, Windows and Linux.

The Termalith window: saved sessions on the left, an SSH terminal in a tab with the Files panel open

Start here

  1. Download and install: pick the right file for your system and get past the first-launch warning.
  2. Your first connection: save a server, confirm its host key, log in, open files.

Feedback welcome

Most features are used daily on macOS. Windows and Linux builds pass automated and real-server tests on every change but have had less hands-on use, so reports from those systems are especially useful.
