This project provides a comprehensive framework for building, training, and managing autonomous agents. It enables the construction of systems that utilize language models to plan, manage memory, and execute multi-step tasks through iterative reasoning loops and tool-based actions. The framework distinguishes itself by offering specialized capabilities for interacting with graphical user interfaces and legacy software, allowing agents to perceive visual elements and perform actions like a human user. It supports complex, cross-application workflows through graph-based orchestration and provid

v86 is a browser-based virtual machine and x86 hardware simulator that allows 16-bit and 32-bit operating systems to run directly within a web page. It functions as an x86 emulator for WebAssembly, simulating CPUs, memory, and storage devices to execute legacy software without original native hardware. The project utilizes a WebAssembly just-in-time compiler to translate x86 machine code into WebAssembly modules for high-performance execution in the browser. The system covers hardware emulation and lifecycle management, including the ability to boot from disk images, configure virtual hardwa

Ruffle is an Adobe Flash Player emulator built to execute legacy animation and interactive content within modern web browsers and desktop environments. By utilizing a high-performance WebAssembly engine, it interprets legacy bytecode and scripting languages to render content without requiring original plugins or outdated software. The project functions as a cross-platform media player that preserves access to archived digital assets by simulating the original runtime environment. The emulator distinguishes itself through its ability to automatically detect and replace obsolete media objects o

Locale-Emulator is an application compatibility layer designed to run software within specific regional and timezone environments. It functions as a regional environment simulator, allowing users to execute programs with custom locale settings to resolve compatibility issues often found in legacy software. The tool operates by intercepting system calls and redirecting requests for locale-specific information, such as character encoding and regional data. By utilizing a translation layer between Unicode and legacy character sets, it ensures that applications relying on older code pages can ren

Bytebot is an LLM desktop automation framework and virtual Linux desktop environment. It enables AI agents to plan and execute mouse and keyboard actions on a virtual computer using natural language, allowing for autonomous desktop automation and the integration of legacy systems that lack native APIs. The system operates as an LLM API gateway and a Model Context Protocol server, routing requests across multiple language model providers with integrated load balancing and rate limiting. It provides isolated, containerized environments where agents use visual reasoning to interpret screenshots

Blink is a JIT-based instruction emulator and x86-64 Linux emulator designed to run Linux binaries and ELF files across different host operating systems and architectures. It functions as a binary execution sandbox and system call simulator, providing a controlled environment for running programs. The project distinguishes itself with a terminal user interface for monitoring execution, managing breakpoints, and visualizing JIT compilation paths. It supports self-modifying code through a cache-invalidating memory model and provides execution environment isolation using restricted directory ove

86Box is a low-level x86 hardware emulator and vintage PC simulator designed to replicate early IBM PC compatibles. It provides virtualized environments for executing legacy operating systems, such as MS-DOS and early versions of Windows, by simulating processors and system designs ranging from the 8086 through the Pentium era. The project distinguishes itself through cycle-accurate processor simulation and high-fidelity hardware emulation. This includes the ability to route retro MIDI audio data to emulated hardware modules or external synthesizers to achieve authentic audio playback from le
