a vs Whaile

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.

Whaile (yes, like the whale) swallows files whole. The multi-gigabyte logs and text files that crash TextEdit and choke VS Code open here in about a second. The ones you'd normally only dare to touch from the terminal. It's native on Mac, iPad and iPhone. Whaile memory-maps the file instead of loading it into RAM, so an 8 GB log opens right away and scrolls smoothly from the first line to the last. No "file too large" error, no progress bar to stare at. WHAT IT DOES • Opens 1 GB, 8 GB or bigger files in seconds • Scrolls smoothly, even 50 million lines in • Searches the whole file and highlights every match • Jumps straight to any line number • Barely touches your RAM: the system pages data in and out as you scroll • Sandboxed and offline, so your files never leave your device WHO IT'S FOR • SREs and platform engineers digging through giant nginx, syslog and crash logs • Data engineers spot-checking a 2 GB JSONL, NDJSON or CSV dump before running the real pipeline • Anyone who got sent a log or an export that's too big for their usual editor LET YOUR AI READ THE FILE On Mac, Whaile has a built-in MCP server: switch it on in Settings and AI assistants like Claude can search and read huge files directly, without blowing through their context window. Point your agent at a 10 GB incident log and ask what went wrong, instead of scrolling through it yourself. WHY IT'S FAST • Memory-mapped access: nothing gets loaded or copied up front • A sparse line index, built in the background, makes jump-to-line instant • Byte-level search written for files that don't fit in memory Whaile is read-only on purpose. It does one job: open, read and search the files that are too big for everything else.
