Shellby is a modern, native SSH client for iPhone, iPad, and Mac — one app, one experience across all your Apple devices. It does more than connect: a built-in AI agent turns plain-language ops tasks into commands you approve one by one, Mosh-compatible transport keeps sessions alive across network changes, and on Mac your AI coding tools reach your servers read-only, fully audited. Built for developers, sysadmins, and anyone who manages remote servers. No account, no tracking. AI ASSISTANT & AGENT (BRING YOUR OWN KEY) • Describe an ops task in plain language — the agent plans and runs it step by step • Every command passes an approval gate; destructive ones need explicit confirmation — nothing runs behind your back • Customizable allow/deny lists; approve & allowlist in one tap • Standard chat-completion APIs, so you pick the service — DeepSeek, Kimi, GLM, Qwen, or a local Ollama model • Off by default; bring your own key and endpoint — no AI service is built in EXTERNAL AGENTS — MCP (macOS) • Let claude-code, codex, and other MCP clients use hosts you already configured — no passwords, keys, or jump-host setup handed over • Read-only: list hosts, run read-only commands, read files, fetch metrics; mutating commands are refused with a reason • Loopback only, token-checked per request, token in the Keychain, every call audited • Runs only while Shellby is open — no background daemon MOSH-COMPATIBLE CONNECTIONS • Switch Wi-Fi to cellular, roam, ride through a tunnel — the session survives and resumes instantly • Typing stays responsive even on slow, high-latency links • Connection test detects a missing mosh-server and gives install steps for your distro TERMINAL • Fast, standards-compliant terminal (xterm-256color) • Password and SSH key authentication (Ed25519 / RSA / OpenSSH) • On-screen key bar: Esc, Tab, Ctrl combos, arrows, symbols • Full hardware-keyboard mapping on iPad and Mac • Terminal themes and font size • Scrollback buffer up to 50,000 lines SNIPPETS & COMMAND TOOLBAR • Save commands you use daily; run, insert, or copy them from a toolbar above the terminal • Shell syntax highlighting and line numbers; review before running DESKTOP-CLASS ON MAC & iPAD • Three-column layout: hosts, sessions, and content each in place • Multiple windows and session tabs, with live terminal previews • Split view, and command broadcast — type once, send to many sessions • Native menu bar, shortcuts, and window toolbar on Mac FILES (SFTP) • Browse, upload, download, rename, move, delete, create folders • One transfer queue both ways — progress, resume, choice of destination • Drag & drop on Mac; notification when background transfers finish • Integrates with the Files app PORT FORWARDING & TUNNELS • Local (-L), remote (-R), and dynamic SOCKS5 (-D) forwarding • Jump hosts / ProxyJump (-J) with multi-hop chains • Standalone tunnels that stay up and auto-reconnect, with live bandwidth • For reaching services inside your own server network (databases, internal dashboards) — not for bypassing network restrictions SERVER MONITOR • Live CPU, memory, swap, disk, load, and top processes SYNC — YOUR DATA, YOUR STORAGE • Optional iCloud sync of hosts, groups, and rules (CloudKit); passwords and keys only via the end-to-end-encrypted iCloud Keychain • Or bring your own storage: hosts, keys, snippets, AI settings & chats via any WebDAV or S3-compatible service you control • Pair a new device by scanning a QR code SECURITY & PRIVACY • Credentials stored only in the device Keychain — never in plaintext • Host fingerprint verification (TOFU), with a strong warning if one ever changes • Face ID / Touch ID app lock • No account, no tracking, no data collection You bring your own SSH servers; Shellby connects only to machines you own or are authorized to access.
