Shellby: SSH Client & Terminal

Shellby is a modern, native SSH client for iPhone, iPad, and Mac — one app, one experience across all your Apple devices. And it does more than connect: a built-in AI agent turns plain-language ops tasks into commands and asks for your approval before running each one. 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 commands step by step • Every command passes an approval gate; destructive actions require explicit confirmation — nothing runs behind your back • Connects via standard chat-completion APIs to the service you choose — e.g. DeepSeek, Kimi, GLM, Qwen, or a local Ollama model • Off by default; you supply your own API key and endpoint — the app ships with no AI service built in

TERMINAL • Fast, standards-compliant terminal (xterm-256color) • Password and SSH key authentication (Ed25519 / RSA / OpenSSH) • On-screen key bar: Esc, Tab, Ctrl combos, arrows, common symbols • Full hardware-keyboard mapping on iPad and Mac • Terminal themes and adjustable font size • Scrollback buffer up to 50,000 lines

PRO ON MAC & iPad • Multiple windows and session tabs • Split view — several sessions side by side • Command broadcast — type once, send to many sessions

FILES (SFTP) • Browse, upload, download, rename, move, delete, create folders • Multi-file transfer queue with progress and cancel • Resumable uploads; 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 average, and top processes

SECURITY & PRIVACY • Credentials stored only in the device Keychain — never in plaintext • Hardware-backed SSH keys in the Secure Enclave • Host fingerprint verification (TOFU) to prevent man-in-the-middle • Face ID / Touch ID app lock • No account, no tracking, no data collection

SYNC • Optional iCloud sync of hosts, groups, and rules (CloudKit) • Passwords and keys sync via end-to-end-encrypted iCloud Keychain • AI provider settings follow your devices; API keys travel only through the encrypted Keychain

You bring your own SSH servers; Shellby connects only to machines you own or are authorized to access.
