Description
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 and asks for your approval before running each one, and Mosh-compatible transport keeps your session alive across network changes. 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
Customizable command allow/deny lists; approve & allowlist in one tap
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
MOSH-COMPATIBLE CONNECTIONS
Switch from Wi-Fi to cellular, roam between networks, ride through a tunnel — your session survives and resumes instantly
Typing stays responsive even on slow, high-latency links
Connection test detects a missing mosh-server and offers install instructions 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, common symbols
Full hardware-keyboard mapping on iPad and Mac
Terminal themes and adjustable font size
Scrollback buffer up to 50,000 lines
SNIPPETS & COMMAND TOOLBAR
Save the commands you use every day; run, insert, or copy them from a toolbar right above the terminal
Shell syntax highlighting and line numbers; review a snippet before you run it
DESKTOP-CLASS ON MAC & iPAD
Three-column layout: hosts, sessions, and content each in their place
Multiple windows and session tabs; session cards with live terminal previews
Split view — several sessions side by side
Command broadcast — type once, send to many sessions
Native menu bar, keyboard shortcuts, and window toolbar on Mac
FILES (SFTP)
Browse, upload, download, rename, move, delete, create folders
One transfer queue for uploads and downloads — progress, resume, and a choice of download destination
Drag & drop on Mac; system 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 average, and top processes
SYNC — YOUR DATA, YOUR STORAGE
Optional iCloud sync of hosts, groups, and rules (CloudKit); passwords and keys travel only through the end-to-end-encrypted iCloud Keychain
Or bring your own storage: sync hosts, keys, snippets, and AI settings & chats via any WebDAV or S3-compatible service you control
Pair a new device by scanning a QR code — nothing to retype
SECURITY & PRIVACY
Credentials stored only in the device Keychain — never in plaintext
Host fingerprint verification (TOFU), with a strong warning if a fingerprint 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.
