DR-Terminal

DR-Terminal is a full terminal for every host on your phone and tablet: SSH, Telnet, SFTP and SCP, USB serial consoles, a dual-pane file manager, SSH key tools and hardware security keys — servers, routers, switches, embedded boards and Raspberry Pi in a single app.

KEY FEATURES:

Terminal
• Own terminal engine: true color, Unicode and full-screen TUI apps — htop, vim, tmux and mc render as they should
• DevOps Keyboard — split terminal keyboard with arrows, modifiers, shortcuts and snippet tiles, adjustable size and opacity
• Output highlighting — colorize logs and command output with custom rules
• Multiple sessions with keep-alive; restart a session in place after a server reboot
• Command history and autocomplete

Connections
• SSH with password, key, keyboard-interactive and hardware security key authentication
• Post-quantum key exchange (sntrup761x25519, mlkem768x25519)
• Jump Host (ProxyJump) for multi-hop connections
• Quick Connect without saving credentials; connection groups
• Automatic server discovery on your local network (Bonjour/mDNS)
• Classic Telnet client for network gear and embedded systems
• Serial port over USB OTG — RS-232 / UART consoles for routers, switches and microcontrollers (FTDI, CP210x, CH34x, PL2303 and CDC-ACM adapters, no root needed)

Files — SFTP, SCP and the Commander
• SCP for hosts without SFTP: OpenWrt, Dropbear and BusyBox routers — Auto picks the transport per host, or pin SFTP or SCP per connection
• Dual-pane Commander: local and remote panels side by side; copy, move and delete between any two locations — server to server too
• Open ZIP, TAR and ISO archives in place, even on remote servers, without downloading
• Built-in viewer for text, Markdown, images and PDF
• Bookmarks and a default directory per connection
• File sharing — send files from other apps straight to a server, over SFTP or SCP

Snippets
• Parameterized command snippets with typed fields and a live command preview
• Built-in catalog of 120+ DevOps commands: packages, services, Docker, network, storage and ZFS
• System-aware variants — the detected host OS picks the right tool (apt, dnf, pacman, zypper, brew, pkg, apk)

Host Insight
• Detected OS, CPU and hardware plus live load, memory, swap and disk gauges in the session sidebar

Keys and Security
• SSH key generation (Ed25519, ECDSA, RSA) — also directly on a YubiKey over NFC or USB
• SSH key converter — OpenSSH, PEM, PuTTY PPK, PKCS#1/PKCS#8, DER
• FIDO2/YubiKey security keys (Ed25519-SK, ECDSA-SK) over NFC and USB
• One-tap migration from password to key-based authentication
• Host key verification with fingerprint display and trusted hosts management
• Encrypted credential storage (Android EncryptedSharedPreferences) — no credentials in plaintext
• Encrypted configuration backup and restore

Customization
• Dark, Light, and System theme; 435 terminal color themes; per-connection theme and font size
• Built-in documentation in 33 languages
