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.

WebPeek brings the four panels you already know to Safari on iPhone and iPad. Turn it on once and every page gets a small floating button; tap it and the inspector slides up over the page you are already reading. ELEMENTS • Tap the picker, then tap anything on the page to select it • A real DOM tree with syntax colouring and a breadcrumb • Edit attributes, text and outerHTML; delete nodes — all applied live • Matched CSS rules, every computed property, and a box-model diagram CONSOLE • Every console.* call captured from the very first line of the page • Uncaught errors, unhandled rejections and CSP violations, with stack traces • Expandable object trees — arrays, Maps, Sets, typed arrays, DOM nodes • An input line for running expressions, with history NETWORK • fetch, XMLHttpRequest, WebSocket, sendBeacon and EventSource, captured as they happen • Status, method, size, and a timing breakdown per request • Request and response headers, request body, response preview • Images, audio and video previewed inline • Copy as cURL, or export the whole session as a HAR file STORAGE • localStorage, sessionStorage and cookies — read, edit, add, delete • IndexedDB browser with paging, including what type each value is • Cache Storage, including what a Service Worker has cached • A usage bar for the origin BUILT FOR A PHONE • The panel lives inside the page — nothing to connect, nothing to install on a computer • Three heights, drag to resize, or a side dock on iPad • Light and dark, English, 简体中文 and 繁體中文 • Every destructive action asks first HONEST ABOUT LIMITS iOS gives Safari extensions a smaller toolbox than a desktop browser, and WebPeek says so instead of pretending. HttpOnly cookies stay invisible, pages with a strict Content-Security-Policy cannot run expressions, static files arrive without headers, and cross-origin responses only show the headers the server chose to expose. The in-app Tips screen explains each one and why. PRIVACY WebPeek reads only the page you are looking at, keeps everything on the device, and has no account, no analytics and no network calls of its own.
