Semantic Developer vs vmux Agent Console

Semantic Developer is a professional SSH terminal built for AI-assisted development workflows. Connect to remote servers, run Claude Code, Codex CLI, or any long-running shell tool, and monitor your work from iPhone or iPad. **SSH terminal for real development** Connect with password or private-key authentication, verify known hosts, and save the connection profiles you use every day. Credentials stay in Apple Keychain, while saved connection metadata remains separate from secrets. **Full terminal emulation** A from-scratch xterm-256color emulator renders your shell output faithfully: 256-color and true-color SGR, bold, italic, dim, inverse, alternate screen, scroll regions, reverse index, DEC line drawing, and application cursor key mode. vim, htop, Claude Code, and other TUI tools render correctly. **Multi-tab workflow** Open multiple SSH sessions as tabs, and on wider layouts view two sessions side by side. Each tab has an activity indicator so you can see output arriving in background sessions without switching away. **Persisted sessions with Pro** Semantic Developer Pro can install an optional helper on a server you control. With your approval, the helper keeps a remote shell running between connections so you can reattach after closing the app, switching networks, or stepping away. **iOS and iPadOS companion** Use the iPhone and iPad app to monitor and interact with remote sessions while away from your desk. A full terminal surface with hardware keyboard support, a software keyboard with terminal-specific accessory keys (Escape, Tab, Ctrl, arrows), and adaptive layout for all screen sizes and orientations. **Built for developers** - SSH with password or private key authentication - Known-hosts verification with configurable policy - xterm-256color and true-color rendering - OSC 7 current directory tracking per tab - OSC 2 window title capture with per-tab display - Git status sidebar for quick diff review - Free edition includes 1 saved connection - Pro unlocks unlimited saved connections and persisted sessions

vmux is a native companion app for the self-hosted vmux server, built for developers running multiple CLI coding agents in tmux. Connect to your vmux server over LAN, Tailscale, or an SSH tunnel, then monitor which panes are idle, working, blocked for input, or in error. The app keeps the attention queue first, so the panes that need you are easy to find. Features: - Queue, Active, All, and tree views for tmux panes - Pane detail view with recent terminal output - Tappable menu choices for supported coding-agent prompts - Custom shortcut keys and saved snippets - Broadcast messages to multiple panes - Server settings and connected-session management - Optional APNs alerts from your own vmux server when a pane needs input - iPhone and iPad layouts vmux is self-hosted. There is no vmux cloud account, no third-party analytics, no advertising SDK, and no developer-operated relay. Your app talks to the server address you configure, and tokens are stored in the system Keychain.
