Open-source alternatives to Hackintool

This project is a GPU feature compatibility layer and frame generation mod. It functions as a DLL API emulator and wrapper that intercepts proprietary Nvidia DLSS Frame Generation calls and redirects them to an alternative implementation. The software enables AMD FSR 3 frame generation in games that natively support only Nvidia DLSS Frame Generation. It translates proprietary graphics requests into an open standard, allowing frame interpolation to run on graphics cards that are otherwise incompatible with the original vendor standards. The system employs DLL proxy wrapping and dynamic librar

Brunch is a boot framework and hardware adaptation layer designed to run ChromeOS on non-native x86_64 PCs. It utilizes a custom EFI bootloader and kernel injection to enable the operating system to function on Intel and AMD processors not originally supported by official images. The framework distinguishes itself by transforming official recovery images into generic bootable versions through the use of custom kernels and EFI partition bootstrapping. It allows for the importation of security keys into system firmware to support secure boot and provides tools to toggle hardware patches and fea

This project provides a specialized UEFI boot environment and hardware emulation layer designed to run proprietary network-attached storage operating systems on generic x86 and x64 hardware. It functions as a bootloader and recovery environment that enables these systems to initialize on devices not originally manufactured by the vendor. The system employs a hardware emulation layer that mimics specific vendor IDs and boot parameters to ensure operating system compatibility. It includes a virtual machine image generator to create bootable images in multiple formats for deployment within virtu

LSPosed is an Android runtime hooking framework and system modification tool. It enables the modification of application and system behavior in memory without altering original installation files, serving as a platform for distributing and managing community-created extension modules. The project provides a comprehensive suite for device and identity spoofing, including the ability to mask hardware identifiers, simulate geographic locations, and conceal root access or hooking frameworks to bypass security and integrity checks. It also functions as an application modder to unlock premium featu

macfuse is a framework for implementing custom file systems in user space. It utilizes a macOS kernel extension to bridge the operating system kernel's virtual file system layer to a user-process daemon. This project allows the implementation of file system logic outside of the kernel to improve system stability and simplify development. It enables the mapping of remote data, network resources, or memory to a local folder so they can be accessed through standard system interfaces. The framework supports the development of cross-platform storage by providing a portable interface for consisten

OpenCore Legacy Patcher is a utility designed to enable the installation and operation of modern operating systems on legacy hardware that is no longer officially supported. By interposing a custom bootloader between the system firmware and the kernel, the project facilitates the deployment of current software releases on older devices, bypassing restrictive compatibility checks and hardware identification requirements. The project distinguishes itself through a comprehensive framework for system interposition and persistent patching. It employs dynamic kernel extension injection and runtime

Momentum-Firmware is a custom firmware replacement for Flipper Zero hardware. It functions as a feature-rich operating system that expands the device's native capabilities through a hardware tooling framework and a device interface customizer. The system includes a peripheral identity spoofer that allows for the alteration of network addresses and vendor identifiers to mimic different hardware devices. It also provides a theme and asset system for modifying visual layouts, animations, and icons. The firmware manages hardware communication via pin-based protocol configuration and frequency-tu

Timeshift is a Linux system restore tool designed to create incremental snapshots of the filesystem to revert an operating system to a previous state. It functions as an automated backup scheduler and a system recovery utility, utilizing either BTRFS atomic snapshots for near-instantaneous restoration or an rsync-based manager to create efficient incremental copies of system files and settings. The tool provides capabilities for automated backup scheduling and rotation at hourly, daily, weekly, or monthly intervals, as well as at every system boot. It manages backup retention to control the n

Redox is a POSIX-compliant, microkernel-based operating system written entirely in Rust. By utilizing a memory-safe language for the kernel and all system components, the project eliminates common vulnerabilities such as buffer overflows and use-after-free errors. Its architecture relies on a minimal kernel that manages only essential hardware and process isolation, delegating all other system services to unprivileged user-space processes. The system distinguishes itself through a modular design where hardware drivers and system services run as independent user-space daemons, allowing them to

CapRover is a self-hosted platform-as-a-service that provides a centralized dashboard for managing containerized applications and databases. It functions as a container orchestration platform, simplifying the deployment, scaling, and networking of services across server environments. By leveraging a reverse-proxy-based architecture, the platform handles domain mapping, traffic routing, and automated SSL certificate lifecycle management to ensure secure, encrypted access for hosted web services. The platform distinguishes itself through its integrated automation capabilities, which include aut

This project is a collection of minimal operating systems, bootloaders, and hardware drivers used to demonstrate low-level x86 system programming and hardware interfacing. It serves as a kernel development toolkit and a system programming lab designed for testing architecture concepts and hardware behavior within a system emulator. The repository provides reference implementations for creating bootable disk images and loading kernel stages. It includes guides for implementing protected mode transitions, memory paging, interrupt descriptor tables, and symmetric multiprocessing on x86 hardware.
