a vs Spectre VPN

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.

A multi-protocol VPN and proxy client for your own servers. Import subscriptions, control traffic with routing rules, and connect from your Home Screen. IMPORT ONCE, KEEP SERVERS TOGETHER Add a server by scanning its QR code, pasting a link, or entering the details yourself. Import subscriptions to manage multiple nodes in one place. Check server latency before choosing a connection. CHOOSE WHAT GOES THROUGH YOUR PROXY Use Global mode for proxy routing, or Rule mode to choose which traffic connects directly and which uses your proxy. Edit your own rules or import a rule list from a URL. CONNECT FROM YOUR HOME SCREEN See the active server and connection status in the widget, then use its switch to connect or disconnect. On iOS 18 and later, add Spectre VPN to Control Center for another quick way to control your connection.
