a-Shell is a complete local terminal emulator, allowing to run most Unix commands on your iOS device. You can transfer files using scp and curl, edit them with vim and ed, process them using grep, awk and sed. You can work with git repositories using lg2.  Most commands are compiled for iOS native Arm64 format, making them fast and well integrated with the BSD Unix that powers iOS/iPadOS. a-Shell includes Python, Lua, Perl, JavaScript, C, C++ for programming and TeX (texlive 2025, with Tikz and LuaTeX) for text processing. There are also multiple network utilities: nslookup, ping, whois, ifconfig... Type help for help, help -l to get the full list of commands. a-Shell can be controlled from Shortcuts: run commands in order, process files in a-Shell, get the results as text or files, transfer files to other apps... a-shell uses iOS 13+ “multiple windows” ability, so you can run multiple shells at the same time, with different commands, in different directories. You can edit a file in one window with vim and process it in the other with python. Compile your C or C++ programs to webAssembly using clang or clang++, and execute the resulting binary. A complete webAssembly SDK is included (WASI-libc). a-Shell is the complete version. If you need a smaller app, and you don't need a C compiler, a TeX engine, or numpy and matplotlib, there is a-Shell mini.

Run AI agents from your phone. A real terminal with a real keyboard, in your pocket. Mobitty is a touch-first SSH terminal built for AI-agent workflows on iOS. You bring the server — self-hosted, behind SSH, Tailscale, or Cloudflare — and Mobitty brings the parts the browser can't: a native on-screen terminal keyboard, multi-URL server rotation, gesture shortcuts, and touch-friendly selection with a magnifier loupe. MADE FOR AI AGENTS A dedicated Claude Code layout. A remote editor that handles Ctrl-G and long multi-line prompts mid-stream. Paste an image straight from the camera roll into the agent's context — your phone becomes the AI-agent dashboard. SESSIONS THAT FOLLOW YOU Sessions live on your server, not your phone. Reattach from mobile or desktop, survive LTE↔Wi-Fi handoffs and subway tunnels. Mobitty's adaptive transport keeps the line open with frugal data usage. A REAL KEYBOARD Readline · Tmux · Vim · Claude Code layouts out of the box. Drag-arrange your own grid, and bind any chord or sequence — Ctrl-Shift-X, a tmux prefix followed by a pane move, Esc :wq Enter — to a single tap. Hardware keyboard paired? Mobitty hides the softkey bar automatically. MULTI-SERVER, MULTI-URL Save Production, staging, and lab boxes once. Each server can list several URLs — LAN, Tailscale, public hostname — probed in parallel until one connects. Drag to reorder, swipe to delete. TOUCH-FIRST, FROM SCROLL TO SELECTION 1:1 momentum scrolling that doesn't fight the terminal renderer. Long-press a word to select, drag iOS handles, and a magnifier loupe rides above your finger so you can land the boundary on the right character — in plain shells and in alt-buffer apps like tmux, vim, and less. SETTINGS THAT MATCH THE DESKTOP Four tabs — General · Softkeys · Gestures · Themes — share the same profile model as the desktop client. Bind 1-finger swipes and flicks to your most-used keys. Edit ANSI palette colors live. BUILT FOR iOS A 3-finger long-press surfaces a quick menu. A right-edge swipe pulls in the native server list. A left-edge swipe opens the session list. iOS 17+, Apple silicon. Source-available · Self-hosted · No telemetry. Your terminal stays on your network.
