Termio

Termio is a local Windows SSH client that brings terminal sessions, SFTP file management, and remote system status into one desktop app.

Features

• Multiple SSH terminal tabs, including multiple connections to the same saved session.
• Session folders and a configurable default session.
• Password or SSH private-key authentication, including encrypted-key passphrases.
• SFTP browsing, upload, download, batch transfer, drag-and-drop, and common file operations.
• Remote system status for CPU, memory, network, disk, and supported GPUs.
• Dark and light themes with dark mode enabled by default.
• Local session and settings storage. Remembered passwords and key passphrases use the operating system credential store; private-key contents are never written to the database.

Quick Start

npm install
npm run dev

Create a session, enter the server address and credentials, then open it from the session list. Use the left sidebar to switch between sessions, SFTP, and system status. Open Settings from the lower-left corner.

For key authentication, select SSH private key in the session dialog and choose an OpenSSH/PEM private-key file. Leave the passphrase empty for an unencrypted key. Paths such as ~/.ssh/id_ed25519 are supported, and the terminal and SFTP use the same authentication settings.

Settings

• Dark or light theme
• Interface font size
• Terminal font family and size
• Cursor style, blinking, and bar width
• Auto-copy selection and right-click paste
• Multi-line paste confirmation
• Default download directory
• Single-instance behavior
• Optional English input-method switching
• Sidebar visibility and width
• Hidden-file display

The interface uses the bundled MiSans font. Terminal background, default text, and cursor colors follow the selected theme while command-defined ANSI colors remain unchanged.
