    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. Zstd can trade compression speed for stronger compression ratios. It is configurable by small increment. Decompression speed is preserved and remain roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.

    CoreCycler

    CoreCycler

    Script to test single core stability

    A PowerShell script to test the stability of single-core loads. Modern CPUs can adjust their CPU frequency depending on their load, and have mechanisms that allow them to clock higher. With this script, you can test the stability for each core, which helps you to validate if your Ryzen "PBO" resp. "Curve Optimizer" settings are actually stable. It also works to test Intel's "Active-Core" Turbo-Boost settings.

    RyTuneX

    RyTuneX

    RyTuneX is a cutting-edge optimizer built with the WinUI 3 framework

    RyTuneX is a comprehensive Windows-system optimization tool aimed at users who want to enhance performance, privacy and usability on systems running Windows 10 (20H1 +) and Windows 11. It is built using the WinUI 3 framework and .NET 8 to provide a modern, responsive interface and native Windows look and feel. The application lets users “debloat” their system by removing pre-installed apps and Windows features that may be unnecessary or resource-heavy, helping free up resources and storage. It also offers system tweaks to improve responsiveness, reduce background overhead, and optimize system settings for gaming or heavy usage workflows. Privacy enhancements are part of its core offering: toggles for telemetry, data-collection features, background apps and more give users greater control over what their OS is tracking or doing under the hood.

    simplewall

    simplewall

    Simple tool to configure Windows Filtering Platform (WFP)

    simplewall is an open-source Windows application that provides a user-friendly firewall control interface powered by Windows Filtering Platform (WFP), enabling users to block or allow outgoing and incoming network connections without diving into complex OS settings or command-line tools. The app presents a clean, intuitive UI where users can define rules based on process names, IP addresses, ports, and protocols, making it possible to restrict apps from accessing the internet or control specific traffic flows with fine granularity. Because simplewall leverages WFP directly, it operates at a low level in the network stack, ensuring reliable enforcement of rules system-wide while remaining lightweight. It also includes optional modes like blocking all inbound or outbound traffic except what’s explicitly allowed, and supports temporary rule application, logging, and diagnostic views to help users understand what traffic is being blocked or permitted.

    Remove Windows Ai

    Remove Windows Ai

    Strip Windows 11 of built-in AI features for control and privacy

    RemoveWindowsAI is an open source PowerShell-based tool created to help users regain control over their Windows 11 experience by disabling or removing AI-related features that Microsoft has increasingly integrated into the OS. It’s designed to work with currently released, stable versions of Windows 11 and continuously updated to match newly added AI components, especially since the 25H2 major update. The script covers a wide variety of AI surfaces (from core features like Copilot and Recall to hidden system packages, registry keys, and ancillary services) and applies targeted removals or disablement in bulk or selectively based on user choice. It offers both a graphical interface with toggles and a more advanced command-line mode, giving flexibility to novices and power users alike. RemoveWindowsAI also includes options to create backups and revert changes if users want to restore functionality later.

    Sandboxie

    Sandboxie

    Sandboxie Plus & Classic

    Sandboxie (and its enhanced fork Sandboxie Plus) is an open-source sandboxing tool for Windows NT-based systems. It creates isolated virtual environments in which applications can run safely without permanently modifying the system, ideal for testing untrusted software. Sandboxie Classic has the old no longer developed MFC-based UI, hence it lacks native interface support for Plus features. Although some of the missing features can be configured manually in the Sandboxie.ini configuration file or even replaced with custom scripts, the Classic edition is not recommended for users who want to explore the latest security options. A completely different token creation mechanism from Sandboxie's pre-open-source version makes sandboxes more independent in the system.

    chromeos-apk

    chromeos-apk

    Run Android Apps in Chrome OS OR Chrome in OS X, Linux and Windows

    Make sure Android applications are compatible with your Chromebook, first try to install an official application. Download an official app, such as Evernote, from the Chrome Web Store. Then download an open source game, like 2048.APK Game by Uberspot and load it as an unpacked extension. Go to chrome://apps and launch it there, ignore warnings. Install a sample Android app from the Chrome Store to get the runtime. Test out that app, make sure it runs on your hardware. Ubuntu might need sudo apt-get install lib32stdc++6. Install Node.js and install the tool (might need a sudo prefix). With Chrome 38+ you can now side load as many applications as you want. If you have older apps that were created using chromeos-apk tool then re-convert them or remove the "key" option from manifest.json.

    Steal a Brainrot Script (Keyless)

    Steal a Brainrot Script (Keyless)

    Keyless Roblox Scripts: Auto Steal Brainrot, AutoLock Base, ESP & more

    (This is Keyless Script work Only Steal a Brainrot Roblox Game) There are already many scripts available for this mode, but our script is truly one of the few that offers significantly more extensive capabilities. The perfect implementation of the Auto Steal feature alone is worth it. Thanks to it, you can automatically steal brainrots from players almost instantly. There are many features, most of which I have listed below. We tested the script using Xeno Executor, and it works perfectly. Therefore, for your convenience, the script comes with an injector that is perfectly suited for it. In this case, it is Xeno. In addition, this script does not require a key, so you can use it without any problems. How to install? Open README.txt for instructions.

    Vita3K

    Vita3K

    Experimental PlayStation Vita emulator

    Vita3K is an experimental PlayStation Vita emulator for Windows and Linux. The emulator currently runs some homebrew programs. It is also able to load some decrypted commercial games. Vita3K is licensed under the GPLv2 license. This is largely dictated by external dependencies, most notably Unicorn. Specify the path to a .vpk file as the first command line argument, or run Vita3K --help from the command-line for a full list of options. For more detailed instructions on running/installing games on all platforms, please read the #info-faq channel on our Discord Server. The project is at an early stage, so please be sensitive to that when opening new issues. Expect crashes, glitches, low compatibility and poor performance.

    Witr

    Witr

    witr exists to answer "Why is this running?"

    witr (short for “Why is this running?”) is a cross-platform command-line utility designed to explain the origin and cause of running processes, services, or anything bound to a port. Traditional tools show what is running, but witr goes a step further by correlating that state across process supervisors, containers, or system services to build a narrative of why the item exists. It supports major operating systems including Linux, macOS, Windows, and FreeBSD, and produces human-readable output that succinctly shows the causal ancestry of a process (e.g., systemd → pm2 → node). witr aims to reduce the time it takes to diagnose processes, especially during debugging or outage investigations, by providing context that would otherwise require manual analysis across multiple tools.
