SemiSSH

Manage SSH servers and development work from your Android phone, tablet, or Samsung DeX workspace.

SemiSSH brings SSH access, server monitoring, file transfers, code editing, database tools, and local web development into one responsive Android app.

SSH AND SERVER MANAGEMENT

• Save and organize SSH server profiles
• Connect through an interactive SSH terminal
• Run a confirmed command across selected servers and reusable server groups
• Review separate results and command history for each host
• Verify SSH host keys before trusting new or changed servers
• Monitor uptime, load, CPU, memory, disk usage, latency, and service health
• View server health from the app or home-screen widget

SECURE SSH KEYS

• Generate non-exportable ECDSA P-256 SSH keys using Android Keystore
• Use StrongBox hardware protection when supported by the device
• View public-key fingerprints and install supported public keys on authorized servers
• Keep private hardware-backed keys inside the device security system

SFTP FILE MANAGEMENT

• Browse and manage remote files and folders
• Work with multiple tabs and optional dual-pane layouts
• Upload and download files through a persistent transfer queue
• View progress, speed, and estimated completion time
• Pause, resume, retry, or cancel supported transfers
• Choose rename, overwrite, or skip behavior when files conflict
• Drag and drop files or complete folder structures from supported Android file managers
• Create SFTP Sync Profiles and review planned changes before transfer
• Compare local and remote text files and prepare reviewed merges

BUILT-IN CODE EDITOR

Edit text and source files directly on Android without depending on an online editor.

• Syntax highlighting and line numbers
• UTF-8 file saving
• Find and replace
• Undo and redo
• Adjustable editor font size
• Coding punctuation toolbar
• Local project files and starter templates
• Visual comparison of local and remote text files

WEBSITES AND DATABASES

Use supported workflows to inspect and manage:

• Nginx, Apache, and Caddy websites
• Website configuration and SSL workflows
• PostgreSQL and MySQL or MariaDB databases
• Database tables, rows, users, and permissions
• Supported server services and installed software
• Website backup and restore operations
• VS Code Web through an SSH tunnel

LOCAL WEB DEVELOPMENT

Build and test projects directly on your Android device with supported local workflows for:

• Built-in web serving
• PHP
• Node.js
• Express
• React with Vite
• PostgreSQL
• MariaDB
• Redis
• SQLite

Create local projects, manage files, inspect logs, select a document root, and open local websites from within the app. Large optional runtime components can be installed only when needed on supported Google Play builds.

PRIVACY AND CONTROL

SemiSSH does not require a SemiSSH account. Connection profiles, trusted host keys, project data, transfer history, and supported credentials are stored on your device.

Optional encrypted Vault features can back up selected settings to a folder you choose. Hardware-backed private keys remain non-exportable.

SemiSSH is intended for servers, accounts, websites, and systems that you own or are authorized to manage. Available features may depend on the Android version, device capabilities, server configuration, installed software, permissions, and network environment.

Interface languages: English and Thai.
