Günther vs Semantic Developer

Your server's command center, from your pocket. Günther connects your iPad or iPhone to your dev machine over SSH and gives you a full command center — dashboard, terminal, GitHub, and AI agent control. No cloud relay, no middleman, no third-party servers. CUSTOMIZABLE DASHBOARD 90+ command templates across 16 categories: system stats, git, Docker, admin, services, logs, GitHub CLI, network, CLI launchers, Claude Code, tmux, deployment, SSL & cron, databases, CI/CD, and file operations. Add from the gallery, build with the guided "Bash Libs" command builder, or create your own. 9 output layouts (gauge, counter, table, log viewer, and more). Real-time polling for CPU, memory, and GPU. One-tap execution for everything else. GITHUB INTEGRATION Browse issues and PRs from your dashboard. Tap to expand, long-press to preview details — title, body, labels, comments, changed files. Send any issue straight to Claude Code with one tap. GitHub OAuth device flow for direct token setup, or use gh auth already configured on your server. Review and approve pull requests from a dedicated PR Approver card. AI AGENT CONTROL Günther reads Claude Code's output and renders it into a real mobile UI — plans, tool approvals, thinking steps, file diffs. A jobs panel tracks file edits, commands, and subagents in real time. Approve, deny, or session-approve tool calls. MCP tools display with server and tool name badges. Discover and invoke skills from the slash command menu. Choose between Sonnet, Opus, and Haiku models. TERMINAL & FILE EXPLORER Full interactive terminal with PTY support, 256-color output, and arrow keys. Browse remote directories with syntax-highlighted file preview. Upload photos and documents over SFTP. WHAT ELSE • Resume sessions exactly where you left off — even after closing the app • Full-screen reconnect overlay when returning from background • Time-sensitive push notifications that break through Focus modes • GitHub issues and PRs at a glance — send to Claude Code with one tap • Import existing SSH keys or generate new Ed25519 keys in-app • Biometric app lock with Face ID / Touch ID • iCloud sync for settings across devices • Light, Dark, and System themes BUILT FOR SECURITY • Direct SSH from device to server — nothing in between • Post-quantum key exchange (ML-KEM) — quantum-resistant encryption • Biometric app lock with Face ID / Touch ID • Built-in SSH key generation and import (Ed25519, RSA, ECDSA) • Keys stored in iOS encrypted keychain • No analytics. No tracking. No telemetry. BUILT FOR PERFORMANCE Flutter UI. Rust SSH engine with post-quantum cryptography. No JavaScript runtime, no Electron, no web views. Native ARM on both sides of the FFI bridge. REQUIRES Claude Code features require Claude Code installed on your server with an Anthropic API key or Claude Pro/Max subscription. Günther is the remote control — it does not include or replace a Claude Code subscription. GETTING STARTED Add a connection. Authenticate. Pick a project. You're running in under two minutes — Günther walks you through SSH key setup during onboarding. WORKS WITH • Mac (macOS) • Linux servers • Cloud VMs (AWS, GCP, DigitalOcean, etc.) • NVIDIA Jetson • Raspberry Pi Free 3-day trial. One-time purchase to unlock — $9.99 launch price ($14.99 after). No subscription. Günther is an independent project by Emberbright Studio, not affiliated with or endorsed by Anthropic, GitHub, Apple, Docker, or any other third party.

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
