About

ModernTerminal SSH

Features

Read full description

ModernTerminal is a modern SSH terminal for remote development, mobile operations, and everyday server maintenance. Create SSH profiles for Linux machines, NAS devices, development hosts, and private servers, then connect quickly with saved host, port, username, and startup command details. The terminal is designed for serious work on a touch device. Use a readable dark theme, monospaced text, arrow keys, Esc, Tab, Ctrl, paste protection, and reusable command snippets for common tasks such as checking Git status, starting tmux, running tests, or inspecting server logs. Credentials stay on your device through Keychain, and host key verification helps you notice unexpected server changes. ModernTerminal is built for developers, operators, indie makers, and anyone who needs secure SSH access away from the desk.
