Shellton vs Codable

Shellton is a native ACP cockpit and persistent SSH/Mosh terminal for developers who want to run coding agents from iPhone without moving their work into a proprietary cloud relay. RUN CLAUDE AND CODEX ON YOUR HOSTS. Connect to a saved SSH or Mosh host, choose Claude or Codex, and start or resume an agent session in the directory where your code already lives. Shellton launches the official Agent Client Protocol adapter on demand and carries the session over your existing encrypted connection—no Shellton account, relay server, or host daemon. AN AGENT INTERFACE BUILT FOR MOBILE. Follow live transcripts, reasoning, tool activity, and plans without squeezing a desktop terminal onto your phone. Approve or deny tool requests, send the next instruction by keyboard or voice, switch between conversations, and hand control back to tmux when you return to a computer. EVERY DROPPED SESSION IS A BUG. Shellton tries Mosh first on every connection. Mosh survives Wi-Fi handoffs, dead zones, and locked-screen suspends. If the server does not have mosh-server installed, Shellton transparently falls back to SSH. VOICE INPUT, ON-DEVICE. Tap the mic and dictate agent prompts or terminal commands. Supported speech engines run on your device; your audio is never sent to Shellton. KEYBOARD THAT WORKS FOR DEVELOPERS. Use a configurable accessory bar with modifier keys, arrows, and custom escape sequences. Build bars in the app or author them in YAML and import them from Files. Hyper, Meh, Kitty keyboard protocol, and tmux prefix shortcuts are supported. FULL-SCREEN TERMINAL. Use a true-color SwiftTerm terminal with Nerd Font glyphs, themes, snippets, per-host history, SSH key management, host-key verification, Live Activities, and tmux-aware navigation. YOUR DATA STAYS YOUR OWN. Shellton uses privacy-preserving product analytics for feature adoption and connection reliability. Analytics never include hostnames, addresses, usernames, commands, terminal text, credentials, voice audio, transcripts, or raw errors, and can be disabled in Settings. There is no advertising or cross-app tracking. SSH keys live in the iOS Keychain, app data remains local, and accessory-bar configuration can sync through your private iCloud container. KEY FEATURES • Native ACP conversations with Claude and Codex • Live transcripts, plans, tool activity, and permission approvals • Direct operation over your SSH or Mosh hosts; no proprietary relay • Auto Mosh-to-SSH fallback per host • On-device voice input • Customizable accessory bar with YAML import/export • Live Activities for active sessions • Ed25519 and ECDSA SSH key generation and import • Optional Face ID protection for stored credentials • Trust-On-First-Use host-key verification • Anonymous, opt-out product analytics; no tracking or ads CONVERSATION REQUIREMENTS • A saved SSH-accessible host with Node.js 22 or later and npm • Authentication with the selected agent provider when prompted • Shellton resolves the official ACP adapter through npx on demand; users do not install a separate Shellton daemon or generic ACP service TERMINAL REQUIREMENTS • iOS 17.0 or later • An SSH server you can connect to • mosh-server on the remote host for persistent Mosh sessions (optional) SHELLTON PRO An optional auto-renewable subscription unlocks voice input, agent conversations, custom accessory bars, and session-continuity tools. Payment is charged to your Apple ID; the subscription renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel it in your App Store account settings.

Codable turns programming practice into a habit. Solve focused challenges in ten languages — from your first data structure to lock-free concurrency — and build real fluency one problem at a time. WRITE REAL CODE IN 10 LANGUAGES C, C++, C#, Go, Java, JavaScript, Python, Rust, Swift, and TypeScript. Switch languages anytime — solve the same challenge in Python today and Rust tomorrow. GO DEEPER THAN SYNTAX Challenges span the topics that actually make you a better engineer: • Fundamentals and string manipulation • Data structures and algorithms • Recursion and functional programming • Object-oriented design and generics • Error handling, concurrency, and memory management BUILT FOR EVERY STAGE New to programming? Start with fundamentals and level up steadily. Experienced? Jump straight into concurrency, memory management, and the problems that show up in technical interviews. PRACTICE THAT STICKS Short, focused challenges designed to fit into a daily routine — because fluency comes from reps, not marathons. Download Codable and start mastering your chosen language!
