    Gobuster

    Gobuster

    Directory/File, DNS and VHost busting tool written in Go

    Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime.

    CrapFixer

    CrapFixer

    Fixes the crap Windows leaves behind

    ...It’s positioned as a fast, no-fluff utility that focuses on practical fixes rather than turning into an overstuffed “optimizer” suite. The workflow is deliberately simple: you analyze your system, review what’s flagged, and then apply recommended changes with a single action. It distinguishes between items that are recommended to fix and items that are already optimized, helping you avoid unnecessary changes. The project emphasizes safety by making most tweaks undoable, and it supports running with administrator privileges when deeper changes (like certain registry locations) are required. ...

    Hangover runs simple Win32 applications on arm64 Linux

    This is Hangover, a project started by André Zwing and Stefan Dösinger in 2016 that currently can run x86_32 Windows applications on aarch64 Wine. Hangover uses various emulators as DLLs (pick one that suits your needs, e.g. works for you) to only emulate the application you want to run instead of emulating a complete Wine installation. As soon as the application does a Windows/Wine system call, say NtUserCreateWindowEx, it's executed outside the emulator (read non-emulated, fast, native)....
