a vs Web Inspector

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.

Web Inspector expands Safari on iPhone and iPad with a set of web development tools: Elements: Browse the DOM tree and tap elements on the page to inspect them. View node details, styles, and computed values. Search the DOM, edit an element's HTML, and copy or delete nodes. Console: Type JavaScript commands to debug, modify, and get information about your webpage. Sources: Read the webpage's source with syntax highlighting. Network: See a list of network requests made by the webpage, with headers and responses. Filter requests, or copy one as a cURL command. Resources: Find details about the data stored by a webpage, such as cookies, local storage, and session storage. Tip: If you tap the Web Inspector button and nothing happens, reload the page once..
